Extech CO260 Portable Indoor Air Quality CO/CO2 Meter/Datalogger

Measures Carbon Monoxide (CO), Carbon Dioxide (CO2), Temperature, Humidity, Dew Point, and Wet Bulb The Extech CO260 monitors indoor air quality for Carbon Monoxide (CO) and Carbon Dioxide (CO2) levels. In high concentrations these gases can affect the health and well-being of people and pets. Monitor CO2 levels in schools, office buildings, greenhouses, factories, hotels, hospitals, transportation lines and anywhere that high levels of carbon dioxide are generated. Common areas to monitor CO levels include boiler rooms, warehouses that use propane and gasoline-powered for lifts, boats, planes, RVs, and manufacturing plants. The CO260 also measures air temperature/relative humidity and calculates dew point/wet bulb temperatures. It can datalog manually up to 99 readings with internal memory or continuously up to 32K readings with included software. Features Manually step through readings of CO, CO2, Dew Point, Wet Bulb, Air Temperature, and Relative Humidity on large backlit LCD with real time clock Built-in maintenance free NDIR (non-dispersive infrared) CO2 sensor Programmable CO warning level with audible alarm Calculates statistical weighted averages of TWA (8 hour time weighted average) and STEL (15 minute short term exposure limit) Pressure compensation adjustment for measuring CO2 at altitudes other than sea level Manually store/recall 99 readings USB interface with PC software for further data analysis Min/Max and Data Hold Auto power off with disable Complete with 4 AA batteries, USB cable, PC software and hard case Optional 33% and 75% RH calibration bottles (RH300-CAL) Specifications Range Resolution Basic Accuracy Carbon Monoxide (CO) 0 to 1,000ppm 1ppm ±10ppm<100ppm, ±10% 101-500ppm,±20%>500ppm Carbon Dioxide (CO2) 0 to 9,999ppm 1ppm ±30ppm+5%reading Temperature -5 to 140°F (-20 to 60°C) 0.1° ±1°F/0.6°C Humidity 0.1 to 99.9%RH 0.1% ±3%RH Wet Bulb 23 to 140°F (-5 to 59.9°C) 0.1° Calculated Dew Point -4 to 140°F (-20 to 59.9°C) 0.1° Calculated Dimensions/Weight 7.9 x 2.7 x 2.3" (200 x 70 x 57mm)/ 6.7 oz (190g) Documentation Instruction Manual Product Brochure
