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 other HVAC device to keep the CO₂ levels below 1,000ppm. The industrial-quality relay closes at 1,000ppm and opens again at 600ppm.

CM-0043-NM - Greenhouse Model - controls CO₂ delivery via a CO₂ generator or a pressurized CO₂ tank control valve. The industrial-quality relay opens at 1,500ppm and closes again at 1,200ppm. Plug this unit into the same timer that controls your light source for a complete indoor greenhouse growing solution.

CM-0044-NM - OSHA - for control /alarms in industrial or storage applications operate at 5,000 ppm releases at 4,500ppm.

CM-0045-NM - HIGH CONCENTRATION - 0-30% CO₂ range for fermentation and incubation applications. Programmable range: specify operate and release levels in special instructions when ordering. Default set for 5% incubation level. Can be user-programmed via RS-485 cable.

All CO₂ Level Controllers are designed to be wall-mounted, and include a 110VAC-24VDC adapter and 10ft of wire. The removable screw terminal block with well-marked connections on the PCB make this a very simple device to install.
