DPM4003
Product Information
The DPM4003 is a 4 digit (-1999 to 9999) LED universal temperature indicator that can be used in any application where temperature needs to be displayed and controlled. This DIN 48mm x96mm, high accuracy, high-quality panel meter is designed for accurate measurement & display (in °C, °F or K) of temperature from thermocouples (selectable from the front push buttons) of Type J, K, N, R, S, T, W5 and from RTDs such as PT100. Ni100 RTD is available as an option as well as other thermocouple types.
The thermocouple and RTD signals are accurately linearised by the internal micro-controller. Options include programmable analogue output, single, dual, three & four alarms, peak hold, RS-232/485 output and more.

| Note 1 | Overall accuracy is dependent on the thermocouple type. The table below lists the designated minimum standard error of some thermocouple types: |
| Note | When the instrument is first installed, it may take a few minutes before accurate readings are shown. This is normally due to the different temperatures between the instrument, panel and thermocouple cable, and these temperature have to stabilise for the cold junction compensation circuit to measure the correct temperature. *** This instrument is designed for non-grounded thermocouple probes only. *** |
