HWL Deluxe humidity transmitters provide an ideal solution for measuring relative humidity in all conditions. All devices are equipped with a thin-film capacitive sensor that is easily replaceable in the field. The wall-mounted HW model features a low-profile housing with an LCD display for easy visibility. All Deluxe models come with an extended five-year warranty. APPLICATIONS   Managing energy systems Controlling HVAC systems for improved comfort and energy savings Museums, schools, printing shops, and other locations requiring humidity control Facilitating compliance with ASHRAE standards for environmental control and indoor air quality Sense humidity in harsh environments   Thin-film polymer capacitive sensor element recovers from 100% saturation Replace element in the field...maintain accuracy and minimize downtime Easy Installation   Polarity insensitive analog output...flexible systems compatibity...save time in the field, and stock fewer devices Calibration-free interchangeable NIST traceable HS element   HS element is microprocessor profiled with on-board nonvolatile memory Minimizes field calibration downtime
