Constant Temperature and Humidity Control System Test Chamber
Programmable Temperature Test Chamber with wide range of temperature controls, mainly used to test performances of materials after in high temperature, low temperature, constant temperature or temperature alternating. It is one of the essential test equipments for aerospace, automotive, home appliances, scientific research department.
QTL-225D Features:
1. Heating/Cooling System: Completely independent heating/cooling system can improve testing efficiency and using life.
2. Cycle System: Powerful blowing cycle system to avoid blind angle, makes temperature and humidity evenly distributed in the test area.
3, Viewing window and interior light makes viewing workspace freely and observe the test under best conditions.
4, HL-1000 touch screen controller is designed to save chamber programming and setup time with temperature limit and alarm to protect your product.
5, Safety relay connection is provided to protect your device under test by removing power to it when the chamber is not running.
6, 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.
7, 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.
8, Adjustable product shelf slides out for easier product access. Shelf design is non-tipping and supports large product loads.
9, Left side of chamber with diameter 50mm cable port for power-on test.
