Description

Humidity calibration system is designed to verify and calibrate dew point meter, humidity sensor. The system is combined by a humidity generator and a dew point mirror, capable of producing dew point temperature from -80°C to +20°C.

The system provides dependable and long-term stable dew point output by approriate proportion of both wet and dry flow and control of moisture. It is integrated with a pressure swing dryer that will generate -80°C or even lower dry air or Nitrogen under general laboratory conditions.

The system features appearance, movable, easy operation, high precision and stability.

Configuration

Reference Hygrometer

The Reference Hygrometer is able to provide a reliable measurment of the calibration gas and offers comparison against humidity sensor, dew point instruments. The Reference Hygrometer 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 Reference Hygrometer has a tracibility to be supplied with either a national standard, or SCS accredited calibration.

3730 has an auxilliary cooling system to reach a lowest -80°C dew point temperature.

Generator

The Generator produces adjusted calibration gas. Preset dew point on the large LCD touch screen and generate desired dew point under general laboratory conditions can produce as low as -80°C or even lower dry air/N2.

Pressure Swing Dryer

The dryer provides a source of dry or super dry air/N2. It is used with the Generator to provide as low as -65°C or even lower dry air/N2.

Calibration Manifold

The experienced engineering team of RAYGE can build your own calibration system that suit any type of dew point instruments, humidity sensors. You may only need to let us know the type of your instrument and we’ll do the rest. Our sales representative wil give you a professional advice according to your request.

Outlook

The whole system is mounted in a 19” rack unit for ease of use and neat appearance.
