| The TL3-A Intrinsically SafeReference Thermometer for Field and Laboratory |
| The Intrinsically Safe TL3-A thermometer is the latest evolution
of ThermoProbe’s industry standard TL series. The TL3-A has
been certified to the latest global standards for hazardous
locations (Ex). |
| A large display and easy to hold design makes the TL3-A more
convenient for use as a reference in the lab or field. The rugged
plastic alloy case and buttons are well suited for use in industrial
applications, even with gloves. The TL3-A innovative circuitry
provides improved temperature accuracy, response time and
battery life. |
| TL3-A thermometers are intended to be used anywhere a
precision glass stem thermometer or other type thermometer is
used |
| Versatile software functions allow easy selection of Celsius or
Fahrenheit units and display resolution. 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. |
| Through numerous distributors equipped for calibration and
repair, the TL3-A can be supported in many locations
throughout the world |
| A one year warranty, protective case and NIST traceable
4 point calibration report are included |
