Programmable Temperature Humidity Alternation Test Chamber with Touch Screen Controller

Programmable Temperature Humidity Alternation
Test Chamber QTH-600C

Brief Introduction:
Programmable Climatic Environmental Test Chamber simulates a full range of temperature and humidity conditions to test reliability, durability, climatic, freezing resistance, quality assurance, thermal endurance etc. It is simple to operate and program easy to edit. It can show the set values and operative time.

Temperature Change Rate of Q1-Test Climate Test Chamber:
Temperature cycling is a method used in many different HALT and HASS tests; therefore the temperature change rate of an environmental test chamber will be important when determining which chamber to purchase.

Variables that affect the pull-down time and ramp up time of a chamber include the chamber size, ambient room temperature, clearance around the chamber, temperature range, and the power of heating and refrigeration systems.

Typically, the larger the chamber, and the more extreme the temperature range, the longer it will take the chamber to reach the maximum (ramp-up) or minimum (pull-down) temperature. Usually, a more powerful heating and refrigeration system will be used for larger chambers to keep these larger chambers’ change rates consistent with smaller chambers within the same series.

Another factor that can affect the pull-down time is whether the refrigeration system is water or air cooled. Water cooled systems typically improve the pull-down time to the minimum temperature opposed to an air cooled system of the same size.

Technical Specifications:

Features:
1, Chamber exterior material is stainless steel with environmentally baking paint resists corrosion and provides impact resistance. Interior material is SUS304# 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).
