Products brief introduction:

1with high precision A/D converter chip, low noise voltage reference and the new single chip microcomputer control software core technology.

2according to the classic air humidity and evaporation of the relationship between design and manufacture. According to the site environment, instrument panel of the touch of the keyboard is arranged for wind speed and atmospheric pressure value, via an internal computer directly after treatment gives high precision values of relative humidity, temperature and dry temperature.

3meters the actual accuracy can be acceptance.

4were provided by two precision paired Pt100 platinum resistance sensor made of measurement, high precision, long service life.

5with third separate channels of temperature measurement and control, and can be used for timing operation. The instrument is suitable for the high precision constant temperature, and humidity box object for automatic control. Can also be used as a condenser and polymer humidity sensor production factory calibration reference device.
