Wall-mounted dew-point meter DewTrans

compactinsertion typechilled mirror

Description
The DewTrans is a high-accuracy, low-cost dew point mirror hygrometer that delivers fast and precise measurements of humidity, dew point, ambient pressure and temperature. It is available as a compact unit or with remote electronics to enable flexible installation. Display and analog outputs (RH, DP or temperature) are user-configurable. The instrument provides stable, repeatable measurements traceable to recognized calibration methods.

User-specific configuration

• Device types: wall mounting
• Pipe mounting
• Sample chamber
• Electronics with remote sensor

Options

• Barometric pressure sensor
• Sample chamber
• Separate temperature sensor
• Higher accuracy option ±0.1 °C

Sensor
The DewTrans uses a wear-free, low-maintenance dew point mirror suitable for most harsh environments. Only minimal maintenance such as mirror cleaning is required to maintain accuracy.

Installation
The transmitter is supplied as a compact or remote version. Remote electronics permit flexible installation; in the compact version the electronics and sensor can be disconnected by a plug for service or remote placement.
