Technical Specification
The HMS110 Series measures relative humidity and temperature across the full 0…100 %RH range with an accuracy of ±2 %RH. By default, the transmitters provide relative humidity and temperature as output parameters, while dew point, wet-bulb temperature, and enthalpy can be selected through a PC connection.
The transmitters use the proven HUMICAP® 180R sensor, a robust and reliable humidity sensor designed for high-humidity environments. Its excellent long-term stability ensures minimal maintenance and consistent performance throughout the product’s lifetime.
Each device is housed in a rugged IP65-rated enclosure with an integrated radiation shield. This design reduces the impact of direct sunshine and ensures reliable outdoor measurement accuracy.
The HMS110 transmitters are easy to install, as they can be mounted directly on a wall or pole without any additional accessories. All connectors are clearly labeled and easily accessible, and screws are secured inside the enclosure.
Calibration can be carried out on-site using either the Vaisala HM70 Hand-Held Humidity and Temperature Meter or a PC connection. For simplified configuration and calibration, the HMS110 is fully compatible with the Vaisala Insight PC software. Each transmitter is delivered with a 3-point traceable calibration certificate.
