Product Overview

The intrinsically safe TL1-W is a modified field version of our successful TL1-A thermometer. It features a rugged frame for reinforcement and is designed for continuous operation but can be easily powered off if desired.

The TL1-W thermometer is intended to be used anywhere a precision glass stem thermometer or other type thermometer may be used. The TL1-W incorporates glass thermometer simplicity and reliability with the ease of a digital display. Like precision mercury thermometers, the TL1-W has accuracy, repeatability and long-term stability. But unlike those thermometers there will never be problems with mercury separation or hazardous material cleanup. Different from most precision electronic thermometers, the “Cordless” TL1-W has no wires to get in the way or break. Battery replacement is easily done through a sealed cover. Encoded calibration is unaffected by temperature, vibration or battery removal. Low battery display, and failure mode indications protect the user from false data.

4 Point NIST Traceable Calibration and a one year warranty included.

NIST GMP 11 - Good Measurement Practice for Assignment and Adjustment of Calibration Intervals for Laboratory Standards

FEATURES exclusive to the TL-1 and TL1-W include: minimum reading, maximum reading, averaging, and easy °F to °C switching. In addition, the display constantly indicates temperature increasing or decreasing activity.
