Detects the presence of carbon monoxide (CO) and measures concentrations between 1-1 parts per million (PPM). The meter indicates the presence of CO by a reading on the LCD and a beeper tone. The beeper functions much like the clicking of a Geiger counter. | CO110 carbon monoxide meter detects the presence of carbon monoxide (CO) and measures concentrations between 1-1000 parts per million (PPM). The meter indicates the presence of CO by a reading on the LCD and a beeper tone. The beeper function much like clicking of a Geiger counter: above 200 PPM, the beeper sounds continuously with the concentration of CO. From 35 PPM to 200 PPM, the beeper sounds discontinuously with the concentration of CO. | Features: Digital LCD display Auto/manual zero Memory for 10 complete data sets Record mode Red & Blue LED light and audible alarm (>90dB) High accuracy, quick response High quality sensor Pocket size and easy to use Fast sampling Max hold Data hold Above 200 PPM, the beeper sounds continuously | Specifications: Operating temperature: 0 ºC to 50 ºC Storage temperature: -30 ºC to 60 ºC Operating humidity:0-90% relative humidity (non-condensing) Measurement range:0 to 1000PPM Measurement resolution:1PPM Accuracy: ±5% or ±10PPM Warm up period: Less than 2 seconds Battery: 9V, NEDA 1604A or equivalent Sensor type: Stabilized electrochemical Gas-specific (CO) Typical sensor life: 3 years Size (HxWxD): 102mm x 52mm x 29mm Weight: 84g Weight: 0.14
