They feature a large 4-digit LED display and a 4-20 mA programmable linearised output signal. They are also field reprogrammable with an optional PC interface module and software, which includes a security feature to prevent accidental reprogramming.

A self-calibration feature helps ensure accurate and stable performance, and an optional fully programmable switch output (relay or transistor) is available.

The temperature indicators come in various mounting configurations, are IP65/NEMA 4 rated and have a 316 stainless steel construction.
