product description
NM-HWS temperature and humidity verification box is a special verification equipment used to detect hair temperature and humidity meters (meters), dry and wet bulb thermometers, digital temperature and humidity meters and other various humidity sensors.
The temperature and humidity verification box is accurately measured by the temperature and humidity sensor and controlled by an industrial programmable controller, which can realize the automatic adjustment of the temperature and humidity in the temperature and humidity verification box. It has high control and measurement accuracy and can provide continuous and repeatable temperature and humidity measurement. , also suitable for scientific research and product testing.
Technical Features
According to the actual needs of a large number of verification temperature and humidity meters, three observation windows are designed, which can verify 10 hair-type temperature and humidity meters at the same time, and the verification efficiency is extremely high.
The double operation hole design on the box allows the inspector to put his hands into the box and adjust the instrument under inspection directly in the box, which greatly improves the verification efficiency.
The unique design of the soaking temperature field makes the box do not need to increase the air flow rate to obtain a uniform temperature field, which not only meets the requirements of the new regulations for the verification of wet and dry bulb thermometers for the wind speed to be less than 0.2 m/s, but also ensures that the temperature uniformity is less than 0.2 m/s. 0.3°C.
Ultra-thick thermal insulation layer, observation window five layers of vacuum glass, cold and heat will not be lost, ensuring rapid and stable heating and cooling.
Automatic timing start, realize the automatic start of equipment before going to work, can read immediately after going to work, save working time.
High-quality controller, long warranty period (two-year warranty for touch screen and controller under normal use conditions).
After installing the corresponding equipment, unattended automatic verification can be realized. The box automatically runs at each verification point, and the digital camera automatically captures the value indicated by the meter and forms a report.
