Johnson Controls® Hx-67x3 Series offers a full line of outdoor relative humidity (RH) transmitters for measuring and transmitting RH levels from 0 to 100%. The RH transmitters provide excellent reliability, long-term stability, and fast accurate response to changes in humidity. Certain models come equipped with a temperature transmitter. The humidity sensor is impervious to dust and most chemicals and is not damaged by condensation. The weather shield protects the
sensors from solar radiation and precipitation without affecting performance. The multiple discs have a unique profile that permits easy passage of air. The disc material is especially formulated for high reflectivity, low thermal conductivity and maximum weather resistance. This rugged enclosure will assure a long life, even under extreme weather conditions. The sensor and shield function as one unit for optimal performance. The RH transmitter can easily be mounted on a roof, pole, or side of a building utilizing its already assembled mounting bracket. It requires no routine maintenance or recalibration.
