PR400 series Dry Block Calibrator

Products Detail


About: PR400 series portable dry block Temperature Calibrator is a portable temperature source which takes advantage of good heat conduction and temperature uniformity of solid metal. It adopts intelligent PID temperature control instrument with small size, light weight, fast speed . It keeps pace with the advanced technology of the world. Which was leading level in temperature stability, horizontal temperature field, and vertical temperature field and so on.

It is suitable for field & laboratory portable calibrators used to calibrate different temperature sensors including RTD Pt-10, RTD Pt-1000, All Thermocouples & also digital temperature indicators. These are Dry Block Calibrators having a multi-hole insert & precision master digital temperature indicator for reference. RS485 comport and communication software can be matched.
