iSense 1% & 30% – IAQ CO2 Level Controller – NEMA4

Product Overview:

The iSense doesn’t just measure CO2 levels, it controls them.

• Control a Fan or Damper (IAQ and OSHA)
• CO2 Delivery or Enrichment (Greenhouse & High Concentration)
• Spray Water Resistant NEMA Level 4 Enclosure
• Hydrophobic filters stopping moisture and spore 

Most inexpensive CO2 controllers skimp on parts like long-lasting CO2 sensors and high-quality relays. The CO2 Level Controller is different: it combines our accurate K-30 NDIR infrared CO2 sensor with an industrial-quality relay capable of controlling up to 10 amps / 250 volts (2500 Watts).

Models:

CM-0042-NM – IAQ Model – controls a damper, fan, or another HVAC device to keep the CO2 levels below 1,000ppm. The industrial-quality relay closes at 1,000ppm and opens again at 600ppm.
