It is suitable for metrology departments, meteorological departments, electronics, electric power, military and other production departments, colleges and universities, and scientific research institutes.

【 Product Features 】

1. According to the actual needs of a large number of temperature and humidity meters, the detection space is large, and multiple mechanical temperature and humidity meters can be detected at the same time, and the verification efficiency is high;

2, the box on the double operation hole design, so that the inspector can deeply into the box, directly in the box to adjust the instrument to be tested, greatly improve the verification efficiency;

3, the use of double high temperature anti-aging silicone seal, can effectively ensure that the experimental area is not affected by the external environment:

4, super thick insulation layer, designed three sides of the observation window vacuum glass, the cold amount of heat does not lose, to ensure the rapid and stable rise and fall; Frost protection devices and controllable lamps for observation;

5, using human-machine interface, touch screen control, good control interface, temperature control logic using programmable controller, can be exported and stored data with one click;

6, the control sensor adopts high-precision temperature and humidity sensor, using the original imported compressor known as "temperature control expert", high stability, with PID parameter self-tuning function, to ensure the system balance, fast and stable.

2. The metering equipment and Internet technology can be closely combined to achieve one-click setting of mobile phone and PC ports. Communication mode: RS-232 interface, can communicate with PC, data reading, system setting. Optional: RS-485 interface, LAN interface, wifi interface.

3. With one-button start, curve display and record function, easy for staff to judge the continuous working state, equipped with a standard - dew point instrument, can be used to verify and calibrate all kinds of temperature and humidity instruments and all kinds of temperature and humidity sensors

● Technology improvement design

1. Unique air circulation design in the box ensures no dead air flow; Frequency conversion technology is used to ensure that the temperature field inside the verification box is uniform

2. Wide humidity range, unique ventilation circulation structure and constant temperature principle are adopted to ensure that the lower limit of relative humidity of the temperature and humidity verification box at 20℃ can reach 5%, and the upper limit of relative humidity can reach 95%.

3. The equipment adopts high-precision humidity sensor and temperature and humidity regulation controller, supplemented by reasonable air flow working principle design, the technical index is far better than JJG205-2005 mechanical hygrohygrometer verification regulation and JJF1564-2016 Temperature and humidity standard box calibration specification (±0.2℃/±0.8%RH). It is also better than the index requirements of JJF1076-2001 humidity sensor calibration specification (±0.5%RH).

4. The device can be upgraded and programmable, and users can perform their own detection Settings according to the detection requirements of different temperature and humidity points. The device is reserved for 10 groups of different program setting interfaces, and each group can set 10 temperature and humidity points to meet the requirements of various detection points. The temperature and humidity verification box is customized according to user needs, equipped with communication protocol or host computer software, and selected.
