Main Features:
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, 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 (support customized) cable port for power-on test.
8, Optional electronic humidity sensor is used on all test chambers for accuracy and minimal maintenance.
Optional Accessories:
1, Cable Port: Size of cable port is available for 100mm, standard is 50mm;
2, Water purifier RO 80: Continuously provide purified water for humidifying heater and wet-bulb;
3, Dehumidifier: The rotation regenerating dehumidifier M-120 ensures precise control of low humidity (10C, 15%RH) for electrostatic reliability tests;
4, Defrosting Device: The chamber automatically detects and melts the frost on the evaporator when operating below 0deg in order to allow continuous operation;
5, Electronic humidity sensor: Precision Humidity Sensor with stainless steel protection tube.
