PR381 series temperature and humidity standard device is a high-performance temperature and humidity generating device, which can be used to calibrate various digital and mechanical temperature and humidity meters. This series of products adopts the temperature and humidity controller newly developed by PANRAN. While expanding the working range of temperature and humidity, its key technical parameters such as humidity control speed and stability have been significantly improved. The product adopts the design of three-sided opening windows, double-sided outlet, and detachable support plate in structure, which can make it easier for operators to carry out temperature and humidity calibration work.
I Features
Humidity can be controlled over wide temperature area
In the temperature range of 20°C to 30°C, humidity control of 10%RH to 95%RH can be achieved, and in the temperature range of 5°C to 50°C, humidity control of 30%RH to 80%RH can be achieved.
Excellent characteristics of humidity control
The application of the new temperature and humidity control technology has not only greatly broadened the temperature and humidity working range, but also greatly improved the key humidity control index, PR381 series standard device can make the humidity stability better than ±0.3%RH/30min.
Dedicated temperature and humidity controller
The new-generation of Panran PR2612 master controller specially designed the decoupling algorithm for temperature and humidity sources，which can automatically control physical quantities such as heating, cooling, humidification, dehumidification and wind speed according to the set temperature and humidity data and environmental temperature and humidity.
Auto/manual defrosting
In order to avoid the humidity control delay caused by evaporator condensation under long-term high humidity operation，the controller will automatically monitor the operation status and activates the rapid defrosting when needed.
Powerful environmental adaptability
It adopts a closed cycle structure, which is not sensitive to the influence factors of environmental temperature and humidity, and has a strong inclusiveness. It can work for a long time in a normal temperature environment of 10°C ~ 30°C.
Powerful human interface
Using a 7-inch color touch screen, it can display a wealth of process control parameters and control curves, and has auxiliary functions such as one-key start, alarm setting, SV preset, and timing switch.
Support PANRAN Smart Metrology APP
After selecting the WIFI module, remote operation of temperature and humidity standard device can be realized by operating with PANRAN Smart Metrology APP. The operation includes checking or changing various real-time parameters, start/stop operation, etc.
