LCD Thermocouple Indicator

Description

The DTM-995B is compatible with K, J and T type thermocouples. It can measure between -200°C and +1300°C (-328°F to +1999°F) when using an appropriate thermocouple.

The current value and maximum/minimum values since power-on are recorded, which can be recalled and displayed by using an external push button connected to the meter.

Calibration can be performed easily using two potentiometers located on the rear of the meter.

Cold-junction compensation is used to maintain accuracy when the meter is exposed to changes in temperature.

The meter is housed in a robust carrier, which can be bolted in place or panel mounted using the low profile bezel, window and clips provided. Backlighting is included for use in poor lighting conditions.

Lascar Product Code: DTM 995B

This product can be supplied with a calibration certificate.

¹ A 5V mode is available by moving DIP switch 2 to the ‘on’ position. Inputting a voltage larger than 5V in this mode may cause permanent damage to the meter.

² Backlighting can be run off the internal voltage regulator by moving DIP switch 1 to the 'on' position. Using backlighting in this way will cause some self-heating of the meter. This can be calibrated out during initial setup, however the final application will need to continue using the backlighting to maintain the calibration.
