Dry block temperature calibrators

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.
