Product Overview: ThermoProbe TL1 R Intrinsically Safe Laboratory Thermometer

ThermoProbe TL1 R


See the ThermoProbe TL3-R here.

The TL1-R thermometer is a compact reference thermometer with accuracy comparable to instrument systems costing twice as much. It has all the features of our standard TL1-A plus a higher level of accuracy. It can be used in applications where extreme accuracy is required. The TL1-R is also perfect for metrology applications and as a calibration reference thermometer. It is an extremely accurate portable hand held instrument that is ideally suited for field applications and indoor laboratory uses.

The ThermoProbe TL1 R uses a precision, 200 Ohm wire wound platinum resistance temperature sensor and attains its high accuracy through our proprietary calibration algorithm.

Standard 5-point Calibration Report, Nominal Points -4°, 32°, 120°, 200°, and 300°F. Report also available in equivalent °C temperatures.
