AM1880 Standard Platinum Resistance Thermometers (SPRT) interpolates temperature in the range from -200 °C to 670 °C on the International Temperature Scale of 1990 (ITS-90). It is designed as a primary or secondary standard thermometer to calibrate other thermometers and/or to measure temperature precisely in primary and secondary laboratories.
The sensing element and sensor support adopt a “Bird-Cage” design and they are protected inside a platinum capsule. Compared to the traditional coil wounding method, the “Bird-Cage” handles mechanical shocks much better at the same time allows for high purity platinum wire to be wound strain-free. The platinum capsule protects the sensing element from contamination at high temperature. The “Bird-Cage” structure combined with 5.56 mm Inconel sheath makes this SPRT responds to temperature changes much faster. All parts used in the SPRT are thoroughly cleaned before assembly and the assembly process is well controlled to protect the sensor from contaminations. The gas mixture filled in the thermometer makes the sensor wire oxidation effect as low as possible.
Every AM1880 SPRT is fully tested for stability after manufactured. This world class probe meets ITS-90 criteria of standard thermometer fully.
