Humidity Oven
LIB humidity oven can also be called temperature and humidity test chamber or constant temperature and humidity chamber. This machine adopts high stability platinum PT-100 temperature resistance body, LCD Chinese and English touch/touch screen, with multiple groups of PID control function, equipped with RS-232C/485C and computer interface control. It can simulate high temperature and high humidity/high temperature and low humidity/low temperature and high temperature/high temperature/low temperature/low temperature and other different environmental conditions. It is also equipped with highly accurate programming control and fixed-point control system that is easy to operate and learn, providing the best test performance.
Description
Xi'an LIB Environmental Simulation Industry is one of the most reliable manufacturers and suppliers of humidity oven in China, featured by quality products and low price. Welcome to buy CE approved humidity oven in stock here and get quotation from our factory. Contact us for discount information.
Humidity oven can provide the temperature and humidity conditions required for all the tests. In any case, the product you test needs to be exposed to certain temperature and humidity conditions, so the most unavoidable test you can avoid in all reliability tests is temperature and humidity detection. LIB thermal shock oven is a reliable, cost-effective device, and we are the most trusted manufacturer brand.
Products Description
Workroom structure and material:
- The workroom generally consists of two layers of sample holders, which are perforated to facilitate air circulation driven by the fan. The sample holder is removable.
- The interior of the workroom is made of stainless steel, which has been treated with high strength anticorrosion and is resistant to acid, alkali, and copper sulfate corrosion.
- Mirror-like design facilitates condensation dripping and workroom lighting.
- The thermal shock oven used to test the battery can increase the explosion-proof function.
- The cable hole is set on the left side of the workroom to energize the test piece. The diameter of the cable hole can be customized, and the standard diameter is 50 or 125 mm.
- The high precision temperature and humidity sensor is installed in the upper right corner of the workroom.

Controller:
- PID programmable controllers enable fast setup and keep process values to a minimum deviation from set values. LIB Industrial PID has extremely high precision, which can achieve ultra-high precision measurement and control of physical quantities such as temperature, vacuum, pressure, flow, tension, etc.
- The operator can pre-set the test program through the controller, a total of 120 programs, each program can perform 999 steps.
- The controller is equipped with a fault alarm device, and the fault alarm information is displayed by SMS or controller panel.
- The interface is simple to understand, and we will have detailed instructions, so that zero-base personnel can easily carry out the test steps.
- Easy installation

Other structure:
-
Water and electricity are separated to ensure safer testing.
-
The equipment is imported from France compressor, refrigeration power, stable performance, long life.
-
A number of safety protections are set, such as phase sequence protection, grounding protection, etc.
-
The equipment is imported from France compressor, refrigeration power, stable performance, long life. Mechanical refrigeration, filling the compressor with environmentally friendly refrigerants.
-
The device is equipped with a water purification and water recycling system, which can be used for about a month at a time.
