1.Product Introduction
Temperature and Humidity Test BoxYes High-precision temperature and humidity field equipment for detecting hair temperature and humidity meters (meters), bimetal temperature and humidity meters and other types of temperature and humidity sensors, and can also be used for high-precision constant temperature and humidity test projects.
The cabinet is made of stainless steel, The outer layer is sprayed to ensure beautiful appearance and corrosion resistance; the control sensor adopts Rodronic humidity sensor and imported temperature sensor, with high precision and good reliability; PIDParameter self-tuning function ensures fast and stable system balance; the control interface adopts advanced touch control screen, which is easy to operate, flexible and functional. Robust for continuous trials of up to several days.
I.Works strong>
1, Humidification: ExpertPIDRegulator controls the injection amount of saturated moisture to achieve a balance.
2, Dehumidification: Forcing moisture to flow through the condenser to form water condensation to achieve the purpose of dehumidification.
3, Temperature control: The isothermal water circulation technology is used to control the overall temperature field to realize the temperature field.

three.Notes strong>
1, The dirt on the transducer of the humidifier will affect the air volume. The transducer of the humidifier should be cleaned regularly with a special cleaning solution.
2, Check whether the humidifier is short of water.
3, Check the liquid level of the temperature control tank. If it is too low, the medium should be replenished in time to avoid burning out the humidifier
4, Check for gaps in doors or operating holes.
5, Running under high humidity, there will be water droplets in the box, which is a normal phenomenon.
6、The compressor is turned off when5can't be turned on within minutes. (with compressor protection function)
7、When measuring the temperature, if the humidity in the box is higher than 80%RH, It is recommended to set the humidity at < span style="font-family:Calibri">60%RH.
8、The test box should be grounded reliably.
