Alternative Temperature Humidity Environmental Test Chamber with
Microprocessor Controller
Brief Introduction:
Temperature and humidity test chambers are available as standard
products in a variety of sizes to suit your needs. Our
environmental test chambers are often used for steady-state
stability testing, basic temperature cycling and accelerated stress
testing.
Air cooled or water cooled?
This might be an easy decision: With water cooled condensers, the
chamber requires a dedicated conditioned waterline. All chambers
can be air or water cooled however water cooled units will lower
the temperature in the chamber workspace faster than an air cooled
chamber.
| Condenser Comparison | Air Cooled | Water Cooled |
| Heat rejection | Positive heat rejection | Little to no heat rejection |
| Energy efficiency | Less efficient | More efficient |
| Footprint | Larger space requirement | Smaller space requirement |
| Pull-down times | Slower rate | Faster rate |
| Purchase price | Less costly for small units | Less costly for large units |
| Installation | Easy | Must supply conditioned water cooling loops |
Features:
1, Touch screen controller is designed to save chamber programming
and setup time with temperature limit and alarm to protect your
product.
2, Safety relay connection is provided to protect your device under
test by removing power to it when the chamber is not running.
3, Chamber exterior material is stainless steel with
environmentally baking paint resists corrosion and provides impact
resistance. Interior material is SUS304# stainless steel with
excellent heat resistance and easy to clean.
4, RS-232 communications is for computer connection, programming
can be set on computer by software, monitor testing process and
automatically execute power on/off functions.
5, Fog-free viewing window and interior light makes viewing
workspace freely and observe the test under best conditions.
6, Adjustable product shelf slides out for easier product access.
Shelf design is non-tipping and supports large product loads.
7, Left side of chamber with diameter 50mm cable port for power-on
test.
8, Optional electronic humidity sensor is used on all test chambers
for accuracy and minimal maintenance.
Unique shape with high performance material, used to testing
aerospace products, electronic instrumentation, materials,
electrical and electronic products and various electronic
components.
Temperature Humidity Test chambers are applicable for quality
inspection for all types of electronic products, electric
appliance, and products from communication ,instruction ,
automobile, plastic, metal, food, chemical, building materials,
medical and aerospace industries.

humidifying heater and wet-bulb
Dehumidifier: The rotation regenerating dehumidifier M-120 ensures
precise control of low humidity (10C, 15%RH) for electrostatic
reliability tests.
Defrosting Device: The chamber automatically detects and melts the
frost on the evaporator when operating below 0deg in order to allow
continuous operation
Electronic humidity sensor: Precision Humidity Sensor with
stainless steel protection tube
