Temperature and Humidity Test Chamber(thermometer and hygrometer calibration chamber -20℃~70℃,10%RH-90%RH)

Product Introduction

The temperature and humidity calibration box is specially developed by our company for calibrating temperature and humidity meters. It has a 360°C observation window without dead angles, and has high stability and fluctuation index. It is a special calibration equipment used to detect hair temperature and humidity meters (meters), dry-bulb thermometers, digital temperature and humidity meters and other types of temperature and humidity sensors. It is suitable for use in measurement departments at all levels, meteorological departments, electronics, electricity, military and other production departments, colleges and universities, and scientific research institutes.

Product Feature

• According to the actual needs of a large number of calibrated thermometers and hygrometers, the detection space is large, and multiple mechanical thermometers and hygrometers can be detected at the same time, with high calibration efficiency;
• The double operation hole design on the box allows the calibrator to put his hands deep into the box and adjust the instrument under test directly in the box, which greatly improves the calibration efficiency;
• The double-layer high-temperature resistant and anti-aging silicone sealing strip is used to effectively ensure that the experimental area is not affected by the external environment:
• The ultra-thick insulation layer is designed with three-sided observation window vacuum glass, and the cold and heat are not lost, ensuring that the temperature rise and fall is rapid and stable; anti-frost device and controllable lighting for observation are set;
• It adopts human-machine interface, touch screen control, good control interface, and temperature control logic adopts programmable controller, which can export and store data with one key;
• The control sensor adopts high-precision temperature and humidity sensor, and adopts the original imported compressor known as "temperature control expert", which has high stability and PID parameter self-tuning function, ensuring the rapid and stable balance of the system.

Programmable functions

It has the function of program update import, which can import the temperature and humidity detection points into the system operating system, and realize one-key start and conversion.

Full range correction function

Realize multi-point correction function, multi-point difference correction of temperature (humidity)

Smart prompt function

The temperature and humidity are automatically calculated in real time. It can intelligently judge whether the calibration box is stable according to the current temperature and humidity fluctuation values. After stabilization, the interface will display the temperature and humidity stability. It also has an intelligent water adding reminder function.
