Analytical constant temperature and humidity testing machine simple troubleshooting method

The constant humidity and humidity testing machine belongs to the detection product performance, thereby improving the product testing equipment. Any problem may lead to the accuracy of the test results. Failure is also inevitable. In fact, equipment failure is not necessarily due to the quality of the equipment itself. Many times it is caused by equipment users who do not understand the product, or operate improperly, or because of changes in the use of personnel, the transfer of incomplete or other reasons. If there is a complex fault such as a cooling system or a control system, contact the factory immediately. In this chapter, Xiaobian explains simple troubleshooting methods for general practitioners.
(a) lighting failure. Phenomenon: The light is not on a) Check if the light is damaged. If damaged, replace it;
b) Check if the ballast is damaged. If it is damaged, replace it.

(B) Door heating wire failure, phenomenon: glass observation window in the low temperature test, observation window glass does not heat.
a) Remove the door heating wire from the terminal and measure it with a multimeter. If damaged, replace it;
b) Check the output voltage of the miniature power transformer. If not, replace it.

(3) The fan's long axis motor has failed. Symptom: The fan motor does not turn a) Check the motor. If damaged, replace it;
b) Check the starting capacitor. If damaged, replace it.

(d) Cooling fan failure. Phenomenon: The cooling fan does not turn a) Check whether the power supply voltage is normal;
b) The fan is damaged. Please replace it with the help of the manufacturer.
Reminder: The user of the equipment should fully understand the structure of the equipment before using the constant temperature and humidity testing machine, carefully read the operating instructions, and use it according to the instruction manual during operation. In case of unclear areas or problems that cannot be eliminated, contact the manufacturer of the equipment in a timely manner. Must not be disassembled without permission.

PT100 Temperature Control

SKYELEC Heater Rod Thermostats are suitable for use with Single Phase to control heating in electroplating baths.They are equipped with a 1.6 metre supply cord and standard red cap terminal casing.


The temperature control probe is suitable for automatic control of a pre-set value in the process media and are suitable for heaters up to 2.3 kw single phase. For higher loads, or three phase heaters an additional contactor should be used.

The probes construction makes it ideally suited for etch, pickle and plating solutions. Its robust construction and chemical resistance ensures a long service life. To set the rod thermostat, unscrew the red cover which provides access to the temperature setting control knob. Turn until the desired temperature is opposite the arrow.


Suitable for use with single phase to control heating of electroplating baths and similar solutions.

Comes complete with heavy duty terminal box and adjustable mounting blocks ready for connection.

Available in: Stainless steel, Titanium, Mild Steel or PTFE.

Alternative lengths are available to order.

The units incorporate an integral 25 amp rated thermostat unit housed with a chemically resistant, PVC coated steel terminal box, complete with quick fix brackets.

The thermostat opens on a rising temperature. Range: 25°C to 100°C. They are suitable for up to 6 kw heaters on a single phase supply. For higher loads or a three phase supply an additional contactor should be used.

The control knob is situated outside the PVC coated terminal box.
