The constant temperature and humidity standard curing box is developed, designed and manufactured in accordance with the concrete shrinkage inspection method and the technical materials provided by the national building materials research and relevant departments. It is suitable for large, medium and small cement plants, construction, water conservancy, highway and bridge engineering, construction engineering Departments, scientific research departments and universities and colleges conduct standard maintenance on the strength and setting time of concrete and cement product samples.
This equipment is based on the original foundation, and has made a series of improvements to the overall shape and internal structure. The box is closed with magnetic tape, electrostatic sprayed shell and stainless steel and stainless iron two inner tanks (optional). Refrigeration, humidification, and equipment have a series of advantages such as beautiful appearance, high precision of temperature and humidity control, and durability.

Structure and working principle:
The box body is composed of inner, middle and outer layers. The outer shell is sprayed with iron plate. The inner tank is welded by two steel plates of mirror stainless steel and stainless steel. The intermediate layer is filled with high-quality insulation materials. The shelf is made of high-quality stainless steel pipes. , The structure is firm, the appearance is beautiful, and the corrosion resistance is good. The shelf wall panels are interchangeable. The humidification system is mainly an ultrasonic humidifier. The automatic control system is automatically switched between refrigeration, heating, and humidification according to a given temperature and humidity by a high-precision control instrument. The temperature and humidity in the box are digitally displayed by the instrument, and the reading is intuitive. , Convenient temperature adjustment.
Using method
- After the box is in place and stand still for 24 hours, connect the ground wire to adjust the level and plug in the power to work.
- Install the humidifier, remove the transparent water tank, turn it upside down, unscrew the bottom cover of the water tank counterclockwise, fill up with clean water (distilled water is best) and screw it back on the humidifier, turn on the power switch to adjust the spray knob Just go to the appropriate location.
- Check the polymer temperature and humidity sensor: open the door to adjust the position of the sensor, and keep it clean during operation to avoid oil pollution.
- Turn on the power, check the temperature and humidity settings of the temperature and humidity controller (the factory has been set), make the instrument work, and when the temperature and humidity in the box reach the given value, put the test piece in, heating and cooling Simultaneously is strictly prohibited.
Common faults and troubleshooting methods:
- The meter has no display:
1.1Check whether the power switch is damaged, if it is damaged, replace it with a new one.
1.2 Check whether the power inlet of the meter is off and tighten the screws.
- The whole machine is not refrigerated:
2.1Whether the setting value of the temperature controller is correct, and the temperature controller does not output a signal.
2.2The temperature controller outputs a signal but the contactor does not work, change the contactor.
2.3 Check if the refrigerant leaks, if the refrigerant leaks, please add F12/F406.
2.4 If the compressor does not work, connect the compressor directly to the power source. If it still does not work, it means that the thermal relay or compressor is burned out and the thermal relay or compressor must be replaced.
- The whole machine is not heated
3.1 The temperature controller and contactor are burnt out and need to be replaced.
3.2If the heating tube is dehydrated and burned out, replace the electric heating element with the same power.
- No humidification if the humidity in the box is lower than the given value:
4.1 Check whether the set value is correct, then connect the humidifier to an independent power socket, turn on the switch to check whether it is sprayed, if it does not spray, the humidifier is malfunctioning.
4.2When the digital display value is lower than the set value, whether the humidification indicator of the humidity controller turns red, if it does not change, the hysteresis value should be appropriately reduced. The humidification indicator turns red without humidification. Check the humidifier.
4.3 If the humidifier does not work normally, first check whether there is scale and impurities on the transducer, and the atomization transducer must be kept clean. Then whether the water tank is short of water, the humidifier is equipped with a water level probe to automatically protect the transducer, and the spray will automatically stop when it is short of water.
4.4Pay attention to clean up the pallet under the cabinet.
- The magnetic tape is not tight
Use heating method to widen the magnetic tape (hair dryer can be used).
