STH Series Constant Temperature and Humidity Test Chamber
The constant temperature and humidity test chamber is suitable for investigating the resistance to moisture of electrical and electronic products, components, parts and materials under different temperature and humidity conditions. It can also be used as an adaptability test for storage, transportation and use in high and low temperature environments.The cabinet is equipped with an independent control system and uses a human-machine interface touch screen controller for simple and intelligent operation.
Product Characteristic
lEasy to operate: Mode color LCD operation screen, display various operating data, users can freely set and save according to their needs.
lEnergy saving and consumption reduction: Using the latest developed intelligent (freezing & dehumidification) system, it can save 30-45% of electricity compared to traditional machines.
lConvenient observation: large observation window and test space lighting.
lCommunication storage: It can be connected to a computer or mobile phone through a LAN or USB port to enable remote control.It has a data acquisition storage interface that can output graphics and Excel data tables.
lComplete series: In addition to standard test chambers, it can also meet non-standard requirements.
Advantages of independently developed programmable controller
lAdopt 7-inch or 10.1-inch industrial control touch screen with higher display frequency.
lSimple interface, all operations can be completed in 3 steps.
lAdopting self-developed internal control algorithm and high-precision acquisition module, it is stable and accurate.
lLow-power refrigeration system, with energy-saving control algorithms, achieves internal balance in refrigeration, rejecting the high-power control mode that relies on heaters for balance.
lWe have independently developed a control system that allows us to better customize for you and make you stand out from the crowd.
