Description

Our latest 3730 Max Plus ultra-low humidity dew point calibration system is dedicated to the verification and calibration of dew point mirror, humidity sensor and gas micro-moisture meter. It is the world's advanced humidity calibration equipment. The ultra-low humidity dew point calibration system is mainly composed of two major optimized devices, the high precision dew point mirror and the automatic low humidity generator in principle of double temperature and pressure. The ultra-low humidity dew point calibration system provides the standard gas dew point temperature ranging from -95 °C to +20°C.

The system has the advantages of beautiful appearance, easy to move, simple operation, high accuracy, stable and reliable performance.

Configuration

Humidity Dew Point

3730 Max Plus Low humidity dew point calibration system is a reliable measurement calibration gas reference unit with standard cold mirror precision dew point measurement. The system is able to provide a reliable measurment of the calibration gas and offers comparison against humidity sensor, dew point instruments. The system measures the temperature at which condensation forms directly and provides repeatable, reliable results. It’s the most suitable for use as a reference instrument.

The  system has a tracibility to be supplied with either a national standard, or NVLAP accredited calibration.

Humidity dew point has an auxilliary cooling system to reach a lowest -95°C dew point temperature.

Generator

The 3730 Max Plus ultra-Low humidity dew point calibration system is designed under the principle of the NIST-proven two-pressure and two-temperature humidity generation principles. Utilizing these principles, a stream of gas at an elevated pressure is saturated with respect to the liquid or solid phase of water at a given saturation temperature. Here, saturation temperature is the major determining factor for the quantity of water vapor admixed with the carrier gas. Pressure within the saturator is the major determining factor for the carrier gas quantity of the mixture. Upon leaving the saturator, the humidified gas stream (consisting of the water vapor admixed with the carrier gas) is then expanded to a lower pressure and warmed to an alternate temperature at the point of use, such as a Device Under Test (DUT). Measurements of the pressure and temperature within the saturator, and the pressure and temperature following expansion (generally at the DUT), are then used to determine the resulting humidity content of the gas stream. Humidity is then accurately controlled by regulation of the temperature and pressure within the saturator.
