1.Temperature and humidity test boxProduct Introduction

The temperature and humidity test box is used to detect hair High-precision temperature and humidity field equipment for temperature and humidity meters (meters), bimetal temperature and humidity meters and other types of temperature and humidity sensors 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, which ensures fast and stable system balance; The control interface adopts an advanced touch control screen, which is easy to operate, flexible and powerful, and can realize continuous tests for several days.

2.Temperature and Humidity Test Box How it works

1, Humidification: ExpertPIDRegulator controls saturated moisture The injection amount reaches equilibrium.

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 achieve an excellent temperature field.

4.Temperature and Humidity Test Box Notes

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 will not be turned on for 5 minutes when the compressor is turned off5. (with compressor protection function)

7、When measuring temperature, if the humidity in the box is higher than 80%RH,It is recommended to set the humidity at 60%RH.

8、The test box should be grounded reliably.
