Dwyer THC-30 : Temperature/Humidity Switch, °F Display, Power Input 20-250 VAC or 24 VDC
The Series THC Temperature/Humidity Switch is designed to measure and control both temperature and humidity simultaneously. It features a dual-display interface: a 3-digit red display for temperature readings and a 3-digit green display for humidity readings. This unit includes four independent relays—two dedicated to temperature control and two for humidity control.
The Series THC supports up to two temperature probe inputs (sold separately) and a compatible humidity sensor. It works with humidity sensors offering 0-1 V, 3 V (THC-P sold separately), or 4-20 mA outputs.
Product Applications:
- Isolation chambers
- Environmental chambers
- Greenhouses
- Beer and wine chillers
