☆ Heating system:

continuousPID regulation, using AC contactors as heating actuators, safe and reliable, with a separate over temperature protection system.

☆Air duct system:

To ensure a high uniformity index, the test chamber is equipped with an internal circulating air supply system; Inside the air duct interlayer at one end of the studio, heaters are distributed

Refrigeration evaporator, fan blades and other devices; Use a fan to circulate the air in the box, and when the fan rotates at high speed, draw in air from the lower part of the workspace

Inside the duct, after heating and cooling, the air is blown out from above the duct, and after heat exchange with the test sample in the working room, it is then sucked into the duct and repeatedly circulated

Ring to meet the temperature setting requirements.

☆ Control system:

Composition of control system:

Temperature measurement:Pt100 platinum resistor;

Humidity measurement:Pt100 platinum resistance dry wet bulb method;

Control device: touch screen programmable temperature and humidity controllerTEMI880。 It can display set parameters, time, heater, humidifier, etc. It also has automatic test operation and PID control

Parameter self-tuning function.The automatic operation function of the refrigeration machine can be achieved by simply setting the temperature. The control system uses an intelligent control software system with automatic combined heating and heating capabilities

The working conditions of the humidity subsystem ensure high-precision control over the entire temperature and humidity range, achieving the goal of energy conservation and consumption reduction. A sophisticated detection device can automatically display detailed faults,

Alarm, if there is an abnormality in the test chamber, the controller will automatically display the fault status.

Screen display: set temperature and humidity; Actual measured temperature and humidity;

Setting accuracy: 1℃

Operation mode: Constant operation；
