Pt-100 Thermometer

The AET-936 is a PT-100 Platinum Resistance Thermometer (PRT) with a selectable high resolution of 0.01°C at a range of -80°C to 200°C or 0.1°C from -200°C to 400°C. The unit is designed to accept a 3-wire configuration, flat film Pt100 sensor probe which offers fantastic accuracy at an affordable price and offers exceptional response time.

The probe connects to the unit using a Lumberg KFV60 plug which is gold-plated to minimise connection errors. Following the constant introduction of directives to reduce the amount of high-accuracy mercury thermometers in use, PT-100 thermometers have become the thermometer of choice for high-accuracy measurement in laboratories and industry.

The increased accuracy also offers a distinct advantage over K-Type thermometers in industrial temperature measurement under 400°C.

When it comes to probes, we offer class A 1/3 din or 1/10 din

IEC 60751:2008 is considered the international standard and specifies the tolerances for platinum RTD elements. The higher the element tolerance the broader it’s range to deviate away from the temperature-resistance curve increasing the level of uncertainty. It should be noted that tolerances defined in the table below only refer to bare detectors and do not account for the design or construction of the complete sensor.

Misinterpretation of tolerance can lead to unnecessary expenditure as people assume closer tolerance assures better accuracy.

Due to the accuracy of the pt-100 thermometer, it is advised that the thermometer & your selection of probe, is purchased together with our UKAS Calibration certificate. The UKAS calibration is then performed as a ‘system’ and our lab technicians can ensure & certify the accuracy of both the thermometer & the probe together.
