Vertical Floor Type Temperature and Humidity Alternate Test Cabinet
with Frostless Window
Brief Introduction:
Temperature and humidity control cabinet can simulate different
environment condition. It's appropriate for testing material
performance, such as resist heat, resist dry,resist humidity and
resist cold. That can define performance of material. It is simple
to operate and program easy to edit. It can show the set values and
operative time.
Humidity versus Temperature:
Electronic Sensor Measurement Chambers made today are typically
equipped with electronic relative humidity sensors as a standard
feature. If the understanding of relative humidity in relation to
temperature is important, then take time to discuss with Q1-Test
your product and needs to monitor humidity and temperature levels.
Features:
1, Chamber exterior material is stainless steel with
environmentally baking paint resists corrosion and provides impact
resistance. Interior material is SUS 304# stainless steel , mirror
finished with excellent heat resistance and easy to clean.
2, Controller imported LCD display screen can be displayed
measuring values and setting the value and time.
3, Safety relay connection is provided to protect your device under
test by removing power to it when the chamber is not running.
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 and right side of chamber with diameter 100mm cable port
for power-on test.
8, Optional electronic humidity sensor is used on all test chambers
for accuracy and minimal maintenance.
9,The French Tecumseh brand is used for the circulation system of
the compressor, more effective removal of oil between the condenser
and the capillary and use environmentally refrigerants ( R23, R404,
R507).
10.Completely independent system separate for testing in high
temperature, low temperature and constant temperature&humidity
