Standard Platinum Resistance Thermometers are widely used as standard or reference thermometers to calibrate other thermometers and to measure temperature precisely in primary and secondary laboratories, and as reference thermometers on dry-wells and temperature baths.
AM1960 covers range from -200 °C to +670 °C.
AM1950 covers range from -200 °C to +500 °C.
The AccuMac AM1960 and AM1950 quartz-clad platinum reference resistance thermometers (SPRT) have a very low drift rate and are affordable, yet highly productive.
To reach the best performance in stability and repeatability, the sensing element and sensor support are specially designed. To protect the platinum sensing wire from contamination at high temperature, all parts used in the thermometer are extremely cleaned before assembly. The assembly process is well controlled to protect the sensor from contamination. The gas mixture filled in the thermometer makes the sensor wire oxidation effect as low as possible. Every SPRT is fully tested for stability after manufactured. This world class probe meets ITS-90 criteria of standard thermometer fully with a very competitive pricing.
