Features: Checks for Carbon Dioxide (CO2) concentrations Maintenance free NDIR (non-dispersive infrared) CO2 sensor Automatic Baseline Calibration (ABC) with disable feature for use in areas with continuously elevated CO2 levels (>400ppm) Triple LCD simultaneously displays CO2, Temperature and Humidity Visible and Audible CO2 warning alarm when concentration level exceeds high or low user set point Calculates Dew Point and Wet Bulb values Min/Max CO2 value recall function Calculates statistical weighted averages of TWA (8 hour Time Weighted Average) and STEL (15 minute Short Term Exposure Limit) Alarm relay output for ventilation control Desktop or wall mount Complete with Universal AC adaptor and multi-plugs (US, EU, UK, AU) Specifications: Carbon Dioxide (CO2): 0 to 9,999ppm 1ppm Temperature (Air): 14 to 140°F (-10 to 60°C) Relative Humidity: 0.1 to 99.9%RH Wet Bulb: Calculated Dew Point: Calculated Dimensions: 5.1x3.4x2.4" (130x85x60mm) The CO230 measures Carbon Dioxide (CO2), Air Temperature and Humidity, plus calculates Dew Point and Wet Bulb. Features Automatic Baseline Calibration (ABC) with disable for use in areas with continuously elevated CO2 levels. Its alarm function with user settable high/low CO2 level is perfect for monitoring air quality and ensuring proper air ventilation in conference rooms, schools, greenhouses, factories, hotels, hospitals and anywhere that high levels of carbon dioxide are generated. The CO230 also calculates Dew Point and Wet Bulb values, Min/Max CO2 value recall function, statistical weighted averages of TWA (8 hour Time Weighted Average) and STEL (15 minute Short Term Exposure Limit), Alarm relay output for ventilation control and wall mount. Complete with Universal AC adaptor and multiple plug types (US, EU, UK, AUS).
