Intrinsically Safe Digital Laboratory Thermometer

• Range: -40/400°F (-40/204°C)
• Accuracy: ±0.05°F (+/- 0.03°C)
• Resolution: 0.001°

The Intrinsically Safe TL3-R is ThermoProbe’s highest accuracy hand-held reference Thermometer. The TL3-R has been certified to the latest global standards for hazardous locations (Ex). Now Bluetooth® connectivity, the TL3-R can be used in applications where extreme accuracy is required. It is powered with 2-AAA batteries providing excellent battery life. A large display and easy to hold design makes the TL3-R convenient for use as a reference in the lab or field. The rugged, weather resistant case and buttons are well suited for use in industrial applications, even with gloves. The TL3-R precision circuitry provides excellent temperature accuracy, battery life and Bluetooth® monitoring.

Versatile software functions allow easy selection of Celsius or Fahrenheit units, Display resolution or Bluetooth® activity. Minimum, maximum and average temperatures are automatically stored to memory for later reference. Low battery display, and failure mode indications protect the user from false data. Encoded Calibration is unaffected by temperature, vibration, or battery removal.

The TL3-R uses a precision, 100 Ohm wire wound platinum resistance temperature sensor and attains its high accuracy through our proprietary calibration algorithm.
