TPI 343C1 - Temperature Tester

The TPI 343C1 is a dual-input K-type thermocouple thermometer that simultaneously measures two temperature points and displays their differential — an essential capability for heat exchanger performance testing, HVAC air handler commissioning, and aircraft ECS diagnostics where supply/return or inlet/outlet temperature difference is a key performance indicator.

Key Features

• Inputs: 2 x K-type sub-miniature
• Accuracy: ±0.3% of reading ±1°C
• Field Calibration: Yes
• Differential Measurement: Yes (T1 - T2)
• Min/Max/Avg: Yes
• Display: Dual 4-digit LCD

Product Description

The TPI 343C1 is a dual-input K-type thermocouple thermometer that simultaneously measures two temperature points and displays their differential — an essential capability for heat exchanger performance testing, HVAC air handler commissioning, and aircraft ECS diagnostics where supply/return or inlet/outlet temperature difference is a key performance indicator. Measuring -58°F to 2462°F (-50°C to 1350°C) with ±0.3% accuracy, the dual 343 handles the full range from aircraft engine temperatures to refrigerant circuit temperatures. Field calibration achieves ±1°F system accuracy in under 10 seconds using ice water. Min/Max/Average recording tracks temperature trends during extended testing.
