The equipment is accurately measured by a temperature and humidity sensor and controlled by an industrial programmable controller, which can automatically adjust the humidity in the temperature and humidity verification box. With high control and test accuracy, it can provide continuous and repeatable humidity measurement, suitable for scientific research and product testing.

Product advantages

○ Excellent technology

Humidity control adopts the shunt method humidity generation principle. Compared with the dual temperature method humidity generation principle, the time required for stability is greatly shortened and the verification efficiency is improved.

Temperature control adopts liquid bath constant temperature and other plate heating technology, liquid medium heat radiation, the temperature is more constant, and the temperature field is more uniform.

The unique air circulation design inside the measuring cavity ensures no dead angle air flow; the frequency conversion technology is used to adjust the speed of the fan to ensure that the internal temperature field is even at low speed.

○ Product intelligence

High-definition touch screen control, multi-touch, greatly improve the user experience.

One-key start, fully automatic control, shorten the training period of measurement personnel.

Timing switch machine, remote switch machine, save time and improve verification efficiency.

○ Excellent quality

The outer shell adopts thick plate phosphating, passivation, spray plastic, anti-corrosion, anti-rust, salt spray resistance.

○ Liner adopts SUS304

High-precision sensor, using imported high-precision platinum resistance, Rotronic humidity sensor for temperature and humidity control.

○ Can be upgraded to an automatic verification system

With the combination of intelligent image acquisition robot, dew point meter and industrial control computer, it can be upgraded to an automatic verification system of intelligent temperature and humidity meter, which realizes the verification process automation, automatic record saving and report generation. It frees the measurement personnel from the reading and recording of the temperature and humidity meter, greatly improving the verification efficiency and reducing the labor cost.
