For Rough Surfaces, For High Precision, For Non-Metals and For Tight Spaces

A CO₂ sensor monitors carbon dioxide levels for safe and healthy air

Monitors moisture and heat for balanced indoor climate

Detects condensation risk for reliable system protection

Collects data from multiple sensors for easy monitoring

Detects water in oil to protect equipment

Measures airspeed to ensure proper flow and system efficiency










It measures CO2 exhaled by people, which indicates room occupancy and ventilation needs.
To maintain good Indoor Air Quality (IAQ), as high CO2 levels impact occupant health, comfort, and productivity.
They enable Demand-Controlled Ventilation (DCV), which saves energy by only providing fresh air to occupied spaces.
Install it on a wall at breathing height (approx. 1.5m / 5ft), away from windows, doors, and air vents.
Indoor levels should be kept below 1,000 parts per million (ppm) for good air quality.
NDIR (Non-Dispersive Infrared) is the industry-standard technology, known for its long-term accuracy and stability.
