Vent Check Plus Product Description

Poor indoor air quality is unhealthy because it causes tiredness, loss of concentration and even illness (e.g. Sick Building Syndrome). Indoor Air Quality (IAQ) monitoring, especially on CO2 levels and air ventilation, is becoming widely applied in public areas such as offices, classrooms, factories, hospitals and hotels. It is also suggested in regulations of industrial hygiene in some countries. The Vent Check Plus CO2 meter uses NDIR (Non-Dispersive InfraRed) technology to ensure reliability and long term stability.

It is particularly useful in verifying HVAC system performance and air ventilation control. The portable meter detects carbon dioxide and temperature. The handheld unit also shows Time Weighted Average and Short-Term Exposure Limit.
