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.
