Pocket Type CO Carbon Monoxide Meter/Detector *****           This low-cost pocket-type meter is designed to check the existence or concentration of CO in the environment. It displays the reading in ppm. The large dual digital LCD give a quick simultaneous overview of the Current and Max Carbon Monoxide levels. It has a long life & reliable electrochemical CO sensor. The audible alarm (beeps at 45db) calls for prompt attention when the exposure safety limit exceeded, adjustable alarm is preset at 25ppm. Top design housing, surround with rails to help air ventilation for quick and accurate response. In addition, it can automatically calibrate at 0ppm or manually calibrate at 100ppm/500ppm carbon monoxide standard gas. This meter can be used in: residential, commercial and industrial settings to monitor CO levels in parking garages or rooms with gas furnaces, central heating furnaces, kerosene heaters, oil burners, stores, water heaters, ranges ovens, stoves or fireplaces.   Special Features Low cost pocket type CO Meter/Detector Adjustable Carbon Monoxide Warning Level Dual digital display: Current CO & Max CO value Auto & Manual power off function Selectable °C and °F Temperature units Auto zero and auto-calibration 2-point CO calibration Auto calibration at 0ppm 100/500ppm for other standard calibration Preset audible alert triggers above 25ppm indicating threshold of dangerous CO concentration High repeatability/selectivity to Carbon Monoxide (CO) Reduced influence by Various interference gasses Long life & reliable electrochemical CO sensor Low battery indicator Backlight, ideal for working in the dark areas Self-Test Function after power on, testing the sensor and circuit condition With overflow and underflow value indication 100% certified safe With EU international standard for health and safety and CE marking which ensures safety   Specifications Measuring Range: 0~999ppm Accuracy: ±20% at 0~100ppm Accuracy:±15% at 101~500ppm Accuracy:(at 20±5°C , 50±20%RH) Resolution: 1ppm Response Time: within 60sec Working Environment Temperature: -10 ~ 60°C Humidity: 5~99% RH (no condensation) Storage Environment Temperature: -40 ~ 70°C Humidity: 0~95%RH(avoid condensation Power Supply: 3 x AAA alkaline batteries Power Supply: (about 250hrs when backlight is off and 35hrs backlight is on) Dimension: 175 x 47 x 28mm Weight: approx. 120g Set Includes 1 x Pocket Type CO Meter 3 x AAA alkaline batteries 1 x Instruction Manual 1 x Wrist Strap 1 x Carrying Pouch Standard colored factory package     Copyright © 2008.
