Huge for JOOOWAY high and low temperature test chamber maintenance detailed instructions

The JOOWAY high and low temperature test chambers must be used. There are many precautions in the process, and maintenance is often required.

This can extend the life of the test chamber and the test machine. The following is a guide from Shanghai Giant for JOOWAY Instruments and the maintenance of constant temperature and humidity chamber.

1. Be sure to check that the water level of the water tank is not too high or too little before doing the test. Allowing the water to overflow the water trap or too low makes the wet bulb test cloth absorb water abnormally, affecting the accuracy of the wet bulb. The water level is about six minutes. The water level of the water tank can be adjusted to adjust the level of the water tank. It is necessary to check almost every two or three tests and add water. You can see the water pipe in front to make up the water. If there is no machine, the machine will alarm and stop working.

2 This machine is equipped with a test hole on the machine side, which can be used when connecting to the test line in the box.

3 If you want to observe the change in the box during the test, you can turn on the LIGHT switch and know the internal changes through the window.

4 If the machine is running below 0 °C, it should be avoided to open the door as much as possible. Because when the temperature is low, if the door is opened, the internal evaporator and other parts will be sealed, especially if the temperature is lower. If it must be opened, the door opening time should be shortened as much as possible.

5 When the low temperature operation is completed, it is necessary to set the temperature condition at 60 ° C for drying for about half an hour, so as not to affect the measurement time or icing phenomenon of the next working condition.

6 The radiator (condenser) of the freezer should be regularly maintained and kept clean.


A measuring instrument is a device to measure a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring Instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty. These instruments may range from simple objects such as rulers and stopwatches to electron microscopes and particle accelerators. Virtual instrumentation is widely used in the development of modern measuring instruments.

The measuring instruments are used frequently in our day-to-day life for the measurement of various quantities like Hardness Tester ,Coating Thickness GaugeUltrasonic Thickness Gauge, Ultrasonic Flaw Detector ,Laser Distance Meter etc. The instruments indicate the value of these quantities, based on which we get some understanding and also take appropriate actions and decisions.
