-40℃ Laboratory use Environmental Chamber , Climate Temperature Test Chamber

Introduction:

-40℃ Laboratory use Environmental Chamber , Climate Temperature Test Chamber is able to provide rapid product temperature change rates and use varying levels of relative humidity to locate design problems prior to shipping your products, improving product quality and reliability.

Specifications :

There are many types of test chambers, but they all high and low temperature limits.

Let's take a look at the typical high temperatures thresholds and why they exist.

Test chambers usually have wire heaters made of a material called Nichrome. By placing successive loops of heater wire, a greater amount of heat that is generated. The result looks a lot like the inside of a toaster. Fans circulate the air past the heaters, so the samples in the chamber are not exposed to radiant heat. It is very easy to add heaters and increase the speed and / or high limit of a chamber.

OTS chambers typically have a high temperature limits under 200°C. Here is a break-down of why a chamber's high temperature limit exists:

150°C: There are two reasons we may limit a chamber to 150°C. First, there may be a limitation of the materials used inside the chamber. Secondly, for extremely fast chambers, we may limit the high temperature to avoid problems with accidentally tripping overheat protection devices.

170-180°C: Most models stop at this temperature range. There is a risk of burning the oil inside the refrigeration's cooling coil.

Stability Temperature Humidity Test Chamber ClimaticTest Chamber Features:

1).The separation of humidifier circuit from electric circuit improves safety and protects the circuit against the leakage of water supply line.

2).Available in Chinese and English LCD touch screen, easy operation and program.

3).Able to display the relative date and information of the whole operating system in running mode, graphic display. precautions, maintenance and troubleshooting appear on the screen instantly.

4).The Sirocco fan motor provides greater cyclic airflow to avoid dead corner in the chamber so as to obtain an uniform distribution of temperature and humidity.

5).The system of heating up, heating down, dehumidifying, and humidifying can be operated independently so as to reduce the cost of testing, extend the operating life of the machine and decrease the failure rate.

6).Water Supply adopts automatic watering System, Circulating water supply together with water filter.
