Constant temperature and humidity box humidity solution:
Temperature and humidity test chamber heating barrel temperature does not go, first check the test box there is no water, generally no water will show an alarm. Check whether the humidification barrel over-temperature protection switch is adjusted to 150 degrees-200 degrees. Over-temperature alarm is generally caused by the humidification barrel without water. When the new machine is running, the temperature can be set to 23, and the humidity is 20%. Run the pump for 5 minutes first and mark the pump with water full of the humidification barrel. At this time, it is necessary to observe whether the pump can pump water. Each water level.
1. Power input of the constant temperature and humidity humidifier: if there is no power or the humidifier is broken, it is impossible to change the humidity; check whether the heat pipe of the humidifier is in good condition, check whether the input and output of the solid state relay can be controlled, and whether the instrument has Output.
2. Whether there is gauze wrapped on the sensor, check whether the humidity cloth is hung on the sensor under the correct position. Place the gauze in the water tank with humidity to ensure that the gauze is wet. Hold the sensor in your hand to see if there is any value on the meter. Changes, if not, indicate that the sensor is broken. In this case, the humidity is not displayed.
3. Humidifier power problem: If the size of the constant temperature and humidity test box is large and the power of the humidifier is small, the humidifier humidification is obviously slow, and there may be no obvious performance;
4. If the meter is broken, there will be no humidity.
Humidity does not go to the constant temperature and humidity box? Constant temperature and humidity can not reach the humidity? In addition, the humidification tube is broken, the water level switch is broken, the contactor is broken, and the cooling capacity is too strong. This is the reason that the humidity of the constant temperature and humidity test box may not be able to go up. The device itself depends on the situation!
