Product introduction
After the temperature and humidity tester is used, the relative humidity measurement sensor needs to be calibrated regularly. Traditional humidity calibration equipment is expensive, bulky, and difficult to popularize. Therefore, Jiantong Technology uses its own deep thermal testing technology foundation and development experience to launch JT8040 The portable humidity calibrator uses the principle that the saturated salt solution produces a fixed relative humidity value in the contact surface with the air under stable conditions, and provides a faster, more accurate, economical and portable humidity calibration method. It is an ideal choice for users such as humidity sensors, portable humidity test instruments, and metering tests.
Calibration principle: at a certain temperature, the partial pressure of water vapor above the saturated salt solution is in equilibrium with the environment and is a constant Basis: JJG 2046-1990 Humidity Measuring Instrument Verification System The humidity value of the saturated salt tank is in line with the value stated in the "Standard Relative Humidity Table of Saturated Salt Solution" by the International Legal Organization (OIM L):
