GMH-3710 Pt100 Precision Thermometer

GMH-3750 Pt100 Precision Hand Held Thermometer

Our GMH-3750 Precision Thermometer represents excellent value for money and out performs many more expensive instruments. It is a development of the popular GMH-3710 thermometer and has some useful additional functions.

The thermometer accepts an input from any 4 wire Pt100 temperature probe and has an very high accuracy of +/-0.03°C and resolution of 0.01°C. When coupled with a 1/10 DIN Pt100 temperature probe the instrument makes an ideal calibration reference. When we have these calibrated in UKAS laboratories we regularly achieve system accuracies better than 0.05°C.

The GMH-3750 is very easy to use and has some useful built in functions such as max., min. and hold functions. In addition to these functions shared with the GMH-3710, the thermometer also has a built in data logger with a memory capacity of 16200 recordings. The unit also has built in audible and visual alarms which are set by the user. Continuous monitoring allows the user to be alerted by an alarm condition. It is also easy to calibrate out any probe errors with both offset and scale functions. Probes are easily connected using a miniature DIN plug which we also stock to be fitted either to our probes or to your own.
