The HMW90 series includes various models for temperature and humidity measurement with current or voltage outputs, as well as optional display and Modbus RTU communication.
The devices are designed for wall mounting and are available in white (optional black). The transmitters feature interchangeable measurement modules and are delivered with a traceable calibration certificate.
Installation is quick and simple, as the electronics can be snapped onto the back plate after wiring. Configuration is performed using internal DIP switches. On-site calibration can be performed via a single-point adjustment or a two-point calibration through the service port using a PC or the Vaisala HM70 handheld device.
