Variety Sizes Climatic Benchtop Environmental Test Chamber
Controlled by Microprocessor
Brief Introduction:
Benchtop Temperature Humidity Test chambers are widely used in
testing various of materials for their tolerances of heat, cold,
dry and humidity.
It is 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.
Unique shape with high performance material, used to testing
aerospace products, electronic instrumentation, materials,
electrical and electronic products and various electronic
components.
Available in several sizes, desk type chambers allow you to cost
effectively and select exact chamber that best meets your
environmental test conditions.
Features:
1, Desk type chamber is optimized to save space while offering a
wide test area, relatively light weight allows setup almost
everywhere.
2, Full variation to select from 3 temperature ranges (0deg,
-20deg, -40deg), and standard volumes (27L and 80L) for selection
to fulfill customers' applications.
3, Cable port is available on both left and up side to allow wiring
for power on testing samples.
4, Fog-free viewing window and interior light makes viewing
workspace freely and observe the test under best conditions,
optional viewing window is available in left side of chamber.
5, 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.
6, Touch screen controller is designed to save chamber programming
and setup time with temperature limit and alarm to protect your
product.
7, Safety relay connection is provided to protect your device under
test by removing power to it when the chamber is not running.
8, 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.
9, Adjustable product shelf slides out for easier product access.
Shelf design is non-tipping and supports large product loads.
10, Left side of chamber with diameter 50mm cable port for power-on
test.
11, Optional electronic humidity sensor is used on all test
chambers for accuracy and minimal maintenance.

Optional Accessories:
Cable Port: Size of cable port is available for 100mm
Water purifier RO: 80 Continuously provide purified water for
humidifying heater and wet-bulb
Dehumidifier The rotation regenerating dehumidifier M-120 ensures
precise control of low humidity (10deg, 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.
