Relative humidity transmitter HI8666

wall-mountwith temperature measurement

The HI8666 is a solid-state, wall-mounted transmitter for on-site, continuous monitoring of relative humidity and temperature in critical or controlled environments. It is equipped with a removable sintered cap, has excellent accuracy, and can communicate signals to remote panel meters, controllers, or data acquisition systems. Integrated sensor Continuous monitoring Removable sintered cap The HI8666 is a solid-state, wall-mounted transmitter for on-site, continuous monitoring of relative humidity and temperature in critical or controlled environments. It is equipped with a removable sintered cap, has excellent accuracy, and can communicate signals to remote panel meters, controllers, or data acquisition systems. Features at a Glance Built-in Sensor - The HI8666 contains a built-in thin-film polymer capacitive (TFPC) sensor that accurately measures relative humidity and temperature. Analog Output Communication - Each 4-20 mA analog signal can be sent to remote panel meters, controllers or data acquisition systems. The signals are to be powered by separate external voltage sources. Sintered Cap Protection - With the sintered cap installed, the sensor is protected from dust and debris prolonging the life of the sensor and the instrument with less maintenance required.
