Temperature Humidity Alternate Environmental Test Chamber with PID Touch Screen Controller
Loading Ratio of a Q1 Climate Test Chamber:
The suggested ratio, for many tests, is about 1:3 for the volume occupied to volume free within the chamber. ⅓ product to ⅔ empty space around the product ensures adequate airflow to the test sample and makes sure your test is conducted properly. Items that allow for airflow (such as a computer chassis with plenty of air vents) can take up a larger percentage of the test volume.
Whereas, sand, dust, and high altitude chambers do not need a 1:3 ratio of product volume and empty space. The airspeed inside the chamber is already very high for the products and makes a 1:3 ratio unnecessary. These chambers should be just slightly bigger than your test product.
Temperature and humidity test chamber 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.
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 environment.
