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.

PR280 electric ventilated wet-dry gauge uses the ventilated dry-wet bulb method to measure relative humidity, so as to avoid the effect of wind speed on the humidity. It can perform multi-point humidity calibration and further improve the measurement accuracy through modifying the wind speed and pressure values. It can also enter the dry-wet bulb sensor certificate value to achieve the sensor data correction. It uses 320×240 dot matrix large-screen LCD display, which can simultaneously display the relative humidity, dry bulb temperature, wet bulb temperature, pressure value, wind speed and other data so as to understand the data information at a glance.

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.

Calibration of general pressure gauge, calibration of precision pressure gauge, calibration of blood pressure gauge, calibration of other pressure gauges, measurement of precision pressure

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.

PR500 series liquid thermostatic bath use liquid as the working medium, which forms a uniform and stable temperature environment through the media heating or cooling as well as mechanical forced mixing and intelligent PID regulation instrument precision temperature control, so as to achieve calibration of a variety of temperature instruments (such as: thermal resistance, glass liquid thermometer, pressure thermometer, bimetallic thermometer, thermocouple, etc.). PR500 series liquid thermostatic bath use the advanced mechanical processing equipment and technology, which fully guarantees the durability of the products. The structure of lateral mixing and the advanced temperature control technology effectively guarantee the temperature field uniformity and temperature fluctuation indicators of the thermostatic bath. Features: 1. Resolution 0.001℃, accuracy 0.01 level. The PR2601 precision temperature control module independently developed by the company is used to achieve 0.01 level...
