GMH-3710 Pt100 Precision Thermometer

GMH-3710 Pt100 Precision Hand Held Thermometer

Our GMH-3710 Precision Thermometer represents excellent value for money and out performs many more expensive instruments.

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. In fact it is so good we use this instrument in our own calibration facility as our temperature references. When we have these calibrated in UKAS laboratories we regularly achieve system accuracies better than 0.05°C.

The GMH-3710 is very easy to use and has some useful built in functions such as max., min. and hold functions. 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.
