GMH-175 hand held thermometer

GMH-175 Pt1000 Precision Hand Held Thermometer

Our GMH-175 hand held thermometer accepts an input from any two wire Pt1000 temperature sensor probe, making it an ideal replacement for thermometers that accept thermistor probes. As Pt1000 sensors are made to internationally recognised standards they offer many advantages. The first is that probes made by different probe manufactures are interchangeable. The second is that we can offer complete flexibility in the probe design you need for your application rather than having to make do with an off the shelf design.

The GMH-175 is also ideal for use in cold store applications. Many hand held instruments do not have a low operating range but the GMH-175 can be used down to -30°C making it suitable for use in deep freezers and similar locations.

The instrument connects easily to your sensor via a commonly available jack plug connector. It is also simple to use with only On and Off buttons.
