PR320 series thermocouple test furnace is the second-generation thermocouple test constant temperature equipment independently developed by the company, and compared with the original KRJ series, the new generation of thermocouple test furnace features wider temperature field and better long-term stability. Its core technology can ensure that the uniform temperature field range and other indicators can exceed the relevant national test requirements.

PR400 series portable dry block calibrator is the portable temperature source which is made by virtue of good thermal conductivity and mean temperature performance of the solid metal block, and is applied with the imported intelligent PID temperature regulator, which features small size, light weight and fast heating and cooling, keeps pace with foreign advanced technology, takes the domestic lead in the temperature stability, horizontal temperature field and vertical temperature field, is suitable for fast temperature comparison/verification at the industrial fields or laboratories, and has the optional RS485 serial communication port and communication software.

The new product (with HART protocol) is provided with dual rows of LCD with backlight, for which 9 pressure units can be switched according to the actual needs of users, and DC24V output function is provided, which can be connected with a variety of pressure sources and is ideal for use on site and laboratory.

PR9140 hand-held micro pressure pump is applied with the insulated pressurized pump body and pipeline, which effectively prevents the impact of the environment on the pressure stability. It features wide micro-pressure adjustment range, high stability, portable structure design, small size and light weight, and is suitable for field operations and laboratory calibration. It is mainly used to calibrate the micro differential pressure transmitter, the differential pressure sensor and the micro-pressure diaphragm pressure gauge.

PR9110 intelligent digital pressure module needs to be used together with PR9113 and PR233 mainframes. It communicates digitally with the host computer and the pressure measurements are unaffected by the ambient temperature. Main applications: Calibration of general pressure gauge Calibration of precision pressure gauge Calibration of sphygmomanometer Calibration of other pressure gauges Measurement of precision pressure Features: Switching between the pressure units such as mmH2O, mmHg, psi, kPa, MPa, Pa, mbar, bar, kgf/c㎡
