The 909 economically-priced Standard Platinum Resistance Thermometers are the workhorse of calibration laboratories all over the world. The wide temperature ranges from -200°C to 670°C and economic pricing make these thermometers ideal for the secondary laboratory.

DESCRIPTIONS

The 909 economically-priced Standard Platinum Resistance Thermometers are the workhorse of calibration laboratories all over the world. The wide temperature ranges from -200°C to 670°C and economic pricing make these thermometers ideal for the secondary laboratory. For smaller uncertainties to suit the Primary Laboratory refer to the 670 SPRTs.

The resistance element is of pure platinum, coiled and mounted in a strain free construction. The former is of pure alumina material and all parts have been pre-aged to eliminate contamination and strain. All joints are welded to minimize resistance changes. The leads are brought to a handle assembly where they are connected to a low loss cable, 2 m long and screened.

The 909Q model has a Quartz sheath while the 909L and 909H have metal sheaths. Quartz glass thermometers have the advantage that the internal components are visible and can be inspected and continue to be our recommended models. The low temperature models have excellent immersion characteristics and a significant cost saving when compared to the higher temperature models.

Three thermometer lengths are available, standard length 480 mm, extra length 550 mm or maximum length 600 mm.
