High Precision constant temperature cabinet for testing thermometer

High-precision thermostat is a special designed thermostat with air as heat transfer medium. It has high accuracy of temperature control, good uniformity of temperature field and low fluctuation. There are many temperature measuring instruments which can not touch the liquid constant temperature source and are not suitable for calibration in the liquid constant temperature bath ,The emergence of high-precision  thermostat solves the calibration problem of such instruments, fills the blank of the constant temperature source, and provides a complete solution for the calibration of temperature measuring instruments.

Calibration project:

Digital Thermometer, Optical Fiber Thermometer, Cold Chain Temperature Recorder, Automatic Meteorological Station Temperature Parameter Calibration, Semiconductor Thermometer Chip, Wireless Sterilization Verification Instrument

Product features

Adopting constant temperature liquid bath technology, the temperature field is more constant

n The temperature control adopts the heating technology of liquid bath constant temperature plate. After controlling the liquid medium in the constant temperature tank to the constant temperature state, it circulates around the working chamber. By means of thermal radiation, the temperature of the working chamber is guaranteed to be constant and even.

Intelligent

n It integrates metering technology with Internet of things technology, and wifi remote control makes metering easier

n Hd touch screen control, multi-touch, greatly improve the user experience,

n One-click start, automatic control, shorten the training cycle for metering personnel

n Timing switch machine, remote switch machine, save time, improve verification efficiency

Wide temperature range

n High precision temperature box series products, can provide - 40 ℃ ~ 100 ℃ constant temperature environment
