CO2 air quality meter EJB 533

portable

EJB 533 PORTABLE CO2-METER •EJB 533 is an absolute interesting CO2-detector with extra measuring functions and automatic calibration. •A big digital LCD-display indicate concentration of gas (CO2), Air Temperature (°C), Dew Point (°C), Wet Bulb Temperature (°C), and Relative Humidity (RH). Datalogging is possible via RS232. •Self test : All functions of instrument (battery status, calibration, CO2 level, activation of acoustic alarm) are controlled by NDIR (Non-Dispersive Infrared) sensor. •Display : multi-digit LCD-display •Monitoring : CO2 (ppm), °C, DP(°C), WB (°C), RH% •Measuring range CO2 : 0-3000 ppm (3001-9999 ppm with low accuracy) •Measuring range temperature : -10...+60°C> •Measuring range relative humidity : 0-95% •Measuring range dew point : 0...+60°C •Measuring range wet bulb temperature : 0...+60°C •Operating temperature : -20 to +50°C •Resolution : 2 ppm CO2 / 0,1°C / 0,1%RH •Accuracy : ± 30 ppm CO2(± 5%)/ ± 0,6°C / 0,1%RH •Sensor CO2: NDIR (Non-Dispersive Infrared)/RH - Rotronic capacitor •Calibration : automatic •Battery life : >10 hours (4 x AA) •Dimensions : 168 x 70 x 55 mm
