Type CSP NTC Temperature Standards

Ultrastable Probe Thermistors

The Type CSP Temperature Standards are ultrastable probe thermistors which have been calibrated to an accuracy of 0.01°C. The standard unit has a thin, conformal coating of silicone rubber over the entire unit; this makes it suitable for immersion in a water bath. They are also available with stainless steel sensor housings, or they can be encapsulated into various sheaths.

Two types of CSP Thermoprobes are stocked for quick delivery: the CSP60BA252M with a nominal resistance of 2500 ohms @25°C; it is furnished with calibration over the range of 0° to 50°C. The CSP60BT103M has a nominal resistance of 10K ohms @25°C and is furnished with calibration  over the range of 0° to 100°C. The calibration table normally furnished with the CSP60BA252M provides data every 0.25°C between 0° and 50°C. The table furnished with the CSP60BT103M provides data every 0.5°C over the range of 0° to 100°C. Both units are furnished with interpolation equations which are accurate to 0.01°C. Tables with calibration data furnished every 0.01, 0.05 or 0.1°C are also available.
