The MicroTherma 1 microprocessor based thermometer measures temperature over the range of -270 to 1768°C with a 0.1°C resolution over the entire range. Each MicroTherma 1 thermometer incorporates an easy to read, custom 4½-digit dual LCD display with open circuit, low battery, hold, max/min and °C/°F indication.

The thermometer should never need re-calibrating as the built-in microprocessor enables the instrument to continuously and automatically carry out self-diagnostic re-calibration. An additional feature allows the user to adjust the reading (±2.5°C) to offset any probe errors, correcting any inaccuracies of the thermocouple probe. Each thermometer thereafter will automatically store, display the offset and adjust the instrument for the known probe error, maximising system accuracy.

The MicroTherma 1 has the versatility of accepting any type K, J, T, R, N, S or E thermocouple probe, the probe type is simply selected through the mode button. The unit incorporates both max and min readings with a reset function and also features an auto-power off facility that maximises the battery life, turning the instrument off automatically after 30 minutes, this function can be disabled if not required. Other selectable parameters include: display contrast and internal CJC temperature reading.

The MicroTherma 1 is sold without a probe. For details of the extensive range of thermocouple probes available click here.
