Programmable cold and hot alternating test chamberProduct Features

The temperature control adopts a fully imported touch button instrument, with simple operation and setting.

After inputting the data and experimental conditions, the controller has a locking function to prevent human touch from changing the temperature value.

Equipped with P.I.D automatic calculation function, it can immediately correct temperature change conditions, making temperature control more precise and stable.

The main component of the electrical control adopts the Korean TEMI300 instrument to better control the temperature

Programmable cold and hot alternating test chamberprecautions

1. The inspection and adjustment of the wet bulb water level in the high and low temperature alternating humidity test chamber should not be too high in the water tank, causing water to overflow from the tank or too low, resulting in abnormal water absorption of the wet bulb test cloth and affecting the accuracy of the wet bulb. The water level should be kept at about six tenths full. The adjustment of the water level in the water tank can adjust the height of the water tank.

2. The replacement of the wet bulb test cloth in the high and low temperature alternating humidity test chamber is necessary when the surface of the test cloth is not clean or hardened, or before continuing to perform temperature and humidity bulb control after completing temperature control. The test cloth should be replaced about every three months. When replacing, the temperature sensor (Sen sor) should be wiped with a clean cloth. When replacing the new test cloth, it should be cleaned first.
3. The cleaning of dust on the condenser of the high and low temperature alternating humidity test chamber should be carried out regularly every month. The condenser should be cleaned with a vacuum cleaner to remove the dust attached to the condenser heat dissipation mesh or sprayed with high-pressure air to remove the dust.
4. During the operation of the high and low temperature cyclic testing machine, the setting of the over temperature protection in the high and low temperature alternating humidity test chamber should be increased by 20 ℃~30 ℃. When the temperature inside the test chamber rises to the set point for over temperature protection, the power supply to the heater stops, and the 'OVERHEAT' over temperature warning light lights up but the fan still runs. If it runs for a long time without supervision, please make sure to check the over temperature protector before operation to ensure that it is properly set (the wet bulb over temperature protector is set to 120 ℃).

High and low temperature alternating machineCleaning and maintenance inside and outside the body
1) The high and low temperature alternating humidity test chamber should be cleaned of internal impurities before operation.
2) The distribution room should be cleaned at least once a year, and a vacuum cleaner can be used to remove the indoor dust during cleaning
3) The exterior of the box should also be cleaned at least once a year, by wiping it with soapy water before cleaning.
High and low temperature alternating machineInspection and maintenance of humidifiers
The water storage in the humidifier should be replaced once a month to ensure clean water quality, and the humidification water tray should be cleaned once a month to ensure smooth water flow.
