Humidity can be one of the most misunderstood topics when it comes to environmental testing chambers. This is because relative humidity percentage is temperature specific. For example, the moisture content in the air at 20˚C (68°F) and 50% RH is not the same as the moisture content in the air at 10˚C (50°F) and 50% RH. As the air cools, so does its ability to hold moisture. Therefore, for a given amount of water vapor in the air, the lower the temperature, the higher the relative humidity. Standard controllable temperature/humidity range for most manufacturers is 5˚C (41°F) to 85˚C (185°F), 10% to 98% relative humidity, limited by 7˚C (44˚F) dew point . The 7°C (44°F) dew point limit can be very confusing. Because humidity levels vary at each temperature, chamber manufacturers use dew point to describe the RH limit.
Character
1. Use the high precision microcomputer touch temperature and humidity controller with high stability of platinum resistance to temperature and wind speed in the circulatory system of temperature and humidity test.
2. control temperature&humidity well-distributed, precisely and steady.
3. Completely independent system separate for testing in high temperature, low temperature and constant temperature&humidity environment.
