QTH3-80B Temperature and humidity test chamber Programmable three
Layers Environmental Test Chamber
Three layers multifunctional Temperature and Humidity Test Chamber
simulates a full range of temperature and humidity conditions to
test reliability, durability, climatic, freezing resistance,
quality assurance, thermal endurance etc.
Application Range:
1, Electronics, electrical appliances, sensors
2, Semiconductor, PCB, LCD & LED
3, Medicals tests
4, Mechanical, Military, aerospace products
5, Vehicles, Transport, automobile supply industries
6, Chemicals, Petrochemical industries
7, Building materials, Plastics, Textile industries
8, Testing metal related industries like plating etc.
9, Instrumentation
Characteristics:
1, 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.
2, Q1-Test HL-1000 touch screen controller is designed to save
chamber programming and setup time with temperature limit and alarm
to protect your product.
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 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.
