Leister Temperature Measuring Device G1200

The Leister Temperature Measuring Device G1200 is a compact K-type thermometer measuring from -65 to 1200 degrees C at plus or minus 0.1% accuracy with three readings per second, backlit display, and compatibility with all standard K-type temperature probes – designed for air flow temperature measurement and plastic extrudate temperature verification on Leister extrusion welding equipment, hot air blower calibration, and general plastic welding process temperature checking on construction sites and in fabrication workshops.

Precise Temperature Verification for Plastic Welding Equipment Setup and Quality Assurance

Plastic welding quality assurance – whether on extrusion welding of thick thermoplastic sheet with FUSION or WELDPLAST equipment, hot air welding of geomembranes or technical textiles, or any other thermoplastic joining process – depends on verified temperature at the point of application rather than assumed temperature from a machine display reading. Machine display values reflect set points and internal sensor readings that may diverge from actual process temperatures due to heat loss along the air path, sensor calibration drift, or ambient temperature effects. The gap between the displayed temperature and the actual temperature at the weld zone is the gap between the welding parameter the operator believes they are applying and the parameter the material is actually receiving.

Closing that gap requires a handheld temperature measuring instrument that can be applied directly at the air outlet, within the extrudate stream, or at the pre-heated substrate surface – providing actual temperature data that the operator uses to set, verify, and document the process conditions that the welding quality assurance programme specifies. The G1200 provides this measurement capability in a 120 gram, 108 mm instrument that fits in a work jacket pocket, delivers a reading within seconds at three updates per second, and covers the full temperature range from the lowest ambient cold-start measurement to the highest process temperatures encountered on extrusion welding and hot air applications. For plastic welding professionals across Oman and the GCC whose work is subject to quality assurance verification, the G1200 is the measurement instrument that makes temperature compliance evidence-based rather than assumption-based.

G1200 Measurement Capabilities and Plastic Welding Application Features

• Temperature Range from -65 to 1200 °C at ±0.1% Accuracy: The G1200 covers a measurement range from -65 to 1200 degrees C at plus or minus 0.1% accuracy – encompassing the full spectrum of temperatures encountered in plastic welding applications from ambient cold-start verification through pre-heating air temperature measurement to maximum extrusion process temperatures – with measurement accuracy sufficient for the process verification requirements of professional plastic welding quality assurance programmes.
• Three Readings per Second for Fast, Responsive Measurement: At three readings per second, the G1200 updates the display rapidly as the probe is positioned at the measurement point and temperature stabilises – providing the operator with a responsive, real-time temperature readout that tracks actual conditions rather than delivering a delayed or averaged value that does not reflect the temperature at the precise measurement point and moment.
• K-Type Probe Compatibility for Measurement Versatility: Compatible with all standard K-type temperature probes, the G1200 accommodates the full range of probe geometries available for different measurement tasks – including straight probes for air flow measurement, immersion probes for extrudate temperature verification, and surface probes for substrate pre-heat confirmation – enabling a single meter body to serve multiple measurement functions across different welding process verification requirements.
• Class 1 Thermocouple Compatibility with Leister Probes: The Leister probes specifically matched to the G1200 (article numbers 136.962 and 136.963) correspond to the best thermocouple class 1 accuracy standard – providing the highest available thermocouple measurement precision for the most demanding plastic welding process verification applications where measurement accuracy directly affects the validity of quality assurance records.
• Backlit Display for Low-Light Site and Workshop Conditions: The backlit display maintains readability in the low-light conditions of enclosed workshop spaces, confined vessel interiors, and construction site environments where ambient lighting does not provide sufficient illumination for clear instrument reading – enabling temperature checks to be conducted and recorded accurately regardless of the lighting conditions at the measurement point.
• Extrudate Temperature Measurement for Extrusion Welding Setup: The primary application of the G1200 on Leister extrusion welding equipment is setting and verifying the optimum welding wire and pre-heating air temperature for FUSION and WELDPLAST extrusion welders – where correct extrudate temperature at the welding shoe directly determines the fusion depth, bead quality, and mechanical performance of the extrusion weld, and where temperature verification is the quality assurance step that confirms the machine is producing weld conditions within the specification range.
• Air Flow Temperature Measurement for Hot Air Welder and Blower Verification: The G1200 measures hot air outlet temperatures on Leister hot air welding tools, automatic welding machines, and hot air blowers – enabling operators to verify actual air temperature against machine display values, identify temperature drift that requires recalibration, and confirm that the welding process is operating within the temperature specification for the material and application being welded.
• Calibration Verification for Leister SOLANO AT Hot Air Blowers: The G1200 is specifically identified as the instrument for calibrating Leister SOLANO AT hot air blowers – providing the temperature measurement accuracy and response speed required to verify blower output temperatures against calibration standards and confirm that the blower is delivering the correct process temperatures for the production applications it supports.
• Compact and Portable for Site and Workshop Daily Carry: At 120 grams, 108 mm height, and 54 mm by 28 mm cross-section, the G1200 is sized for daily carry in a work jacket or tool bag alongside the welding equipment it supports – enabling temperature checks to be conducted at any point in the workday without returning to a dedicated instrument storage location or carrying a separate instrument case to the work point.

Temperature Measurement Applications for the Leister G1200 in Plastic Welding and Construction

• Extrusion Welder Process Temperature Setup and Verification: Measures extrudate temperature and pre-heating air temperature on Leister FUSION and WELDPLAST extrusion welders during initial machine setup and periodic process verification – confirming that the extrudate is within the optimum temperature range for the thermoplastic material being welded and that the air pre-heating temperature is correctly set for the base material and ambient conditions on site.
• Hot Air Welding Temperature Verification on Site and in Workshop: Verifies air outlet temperatures on Leister hot air welding tools and automatic welding machines used for geomembrane overlap welding, technical textile seam welding, and thermoplastic sheet welding – providing the actual temperature measurement that confirms the machine is operating within the process specification for the liner material, welding speed, and ambient conditions of the specific installation.
• Geomembrane Installation Quality Assurance Temperature Checks: Supports the quality assurance temperature verification programme on geomembrane liner installations in civil engineering projects across Oman and the GCC – where periodic temperature checks of welding equipment are a documented quality assurance requirement and where the G1200 provides the measurement evidence that confirms equipment compliance with the welding process specification.
• Hot Air Blower Calibration and Performance Verification: Measures the air outlet temperature of Leister hot air blowers including the SOLANO AT for calibration verification and periodic performance confirmation – identifying temperature output drift that signals calibration requirement before the drift reaches a magnitude that affects production weld quality on process lines that depend on blower temperature accuracy for consistent heat application.
• Workshop and Production Facility Plastic Welding Equipment Checks: Supports the routine temperature verification programme for plastic welding equipment in fabrication workshops and production facilities – where periodic temperature checks of hot air tools, extrusion welders, and automatic welding machines are part of the equipment maintenance and quality system compliance schedule that the facility’s welding quality assurance programme requires.
