Product Description

In today’s complex technical society, devices for combining and controlling the overall nature environment such as the temperature, humidity, noise and impact are more needed.

Such devices conditioning the environment are used in the technical research development, new product development and performance improvement in the basic science as well as in the technical application and are used in the product test, performance test, reliability evaluation, durability test, etc. in the manufacture field, thereby improving it’s value every day.

Accordingly, COSTAL tester business department consistently researches and develops various types of enviroment testers and equipment based on the excellent technology to meet the customer requirement.

– The constant temperature & humidity chamber has the precise controllability and temperature & humidity repeatability without setting and reading errors by using the PID digital program.

– The constant temperature & humidity chamber maintains heating and cooling, mutual dehumidification balance and conditions the temperature and humidity by applying the non-contact control method to the control circuit to provide the stability and convenience.

– A specially designed fan is installed in the chamber and applies the air blowing circulating method to have the excellent distribution performance by removing most of indoor temperature and humidity deviation.

– The automatic feed method is applied to the humidification tank and wet-bulb water-saturated tank to reduce the inconvenience of water supply.
