The E+E EE211 humidity and temperature sensor is engineered for polluted, aggressive environments. It features a continuously heated humidity probe that protects against condensation and high humidity, along with an interchangeable temperature probe. The measurement electronics are fully encapsulated inside the humidity probe, and the HCT01 sensing element is protected by E+E's proprietary coating, which extends sensor lifetime and prevents stray impedances from deposits in dusty, oily, or corrosive applications.

The EE211 measures -40 to 60°C (-40 to 140°F) with a display option for -20 to 50°C (-4 to 122°F). Humidity accuracy is ±(1.3 + 0.007 * measured value) % RH, and temperature accuracy is ±0.1°C. The IP65/NEMA 4 enclosure with bayonet screws minimizes installation costs and ensures outstanding protection.

All measured and calculated values are available on the Modbus RTU interface, with two values also available on analog voltage or current outputs (3-wire). An optional USB configuration adapter allows users to set Modbus parameters, display format, measured parameters, output scaling, and perform one- or two-point humidity and temperature adjustments.
