Key Features:

  • Versatile Outputs: Delivering 3x 0-10V analog signals for CO2 (PPM), Temperature (°C or °F), and Humidity (% Relative), alongside digital RS-485 communication supporting Modbus RTU or BACnet MS/TP protocols.
  • Reliable Operation: Equipped with a VFC Relay for CO2 and a thermistor output for third-party temperature monitoring, ensuring seamless integration and dependable functionality.
  • Robust Construction: Designed for straightforward wall mounting with a 1/2” DIA rear entry and snap-offs for side trunking, encased in a durable ABS UL Flame retardant housing, assuring longevity and safety in diverse environments.
  • Flexible Power Options: Compatible with 12-24V AC/DC or 120VAC electrical systems.
  • Optimal Performance: Exhibiting rapid response times, quick warm-up periods, and excellent long-term stability, with minimal interference, guaranteeing accurate readings and consistent operation over time.

Technical Specifications:

  • Temperature Monitoring: Offers a normal indication range of 32-122°F, with a swift response time of t63% @ 77°F in approximately 20 seconds, an accuracy of ±0.5° @ 50-113°F, and a resolution of 0.1°.
  • Humidity Sensing: Provides indication across a range of 0-100% RH, with a quick response time of t63% @ 77°F in about 8 seconds, an accuracy of ±2% @ 59-86°F (20-90%RH), and a resolution of 0.1%.
  • Carbon Dioxide Detection: Utilizes diffusion type NDIR sampling with an indication range of 400 – 5000ppm, boasting a response time of t90 <120s, and an accuracy of 5% FS @ 77°F, ensuring precise CO2 monitoring over its lifespan of > 5 years.

Backed by a standard 2-year manufacturer's warranty, proudly designed in the USA and manufactured in the UK. The RS Carbon Dioxide, Temperature & Humidity Room Sensor range offer unparalleled performance, reliability, and versatility for comprehensive air quality monitoring solutions.
