AM1762-20 Secondary SPRT
AccuMac's AM1762-20 series 25 ohm Secondary SPRT is an affordable SPRT probe for precision temperature measurement either in the lab or out in the field.
Rtp/R0 25, Alpha 0.003925
Accuracy ±0.006 °C at 0.01 °C
Long term drift: ±0.019 °C
Short term stability: 0.002 °C
The probe diameter is 6.35 mm and two different lengths of SPRTs are available at 300 mm for the 1762-12 model and 500 mm for the AM1762-20 model.
100 ohm SPRTs offer more sensitivity or achieve a better resolution for the same amount of temperature change while 25 ohm SPRTs offer excellent durability and stability over time.
The sensing element is designed to protect the platinum sensing wire from contamination at high temperatures, giving the device a high level of stability and repeatability in performance.
A uniquely designed support structure and filling material provides excellent balance between the hysteresis effect, mechanical shock and thermal shock performance. This high performance probe fully meets ITS-90 criteria for reference thermometers.
Wooden carrying case is an optional extra
