GAOTek Formaldehyde Gas Leakage Detector

Description Overview GAOTek formaldehyde gas leakage detector alarm system gas leakage detector to measure formaldehyde CH2O with pump built in. It adopts 2.31 inch high-definition color screen for real-time display and adopts gas sensors of well-known brands in the industry. It is used to quickly detect the concentration of various gases and the measurement of ambient temperature and humidity, and alarm if the measurement exceeds the limit. It is suitable for detecting gas concentration in pipelines or confined spaces and atmospheric environments gas leakage or high concentration single gas purity where various background gases are nitrogen or oxygen. There are more than 500 kinds of detected gases.   Features It can detect 1 to 4 kinds of gasesat the same time, and the unit can be switched Built-in pumping measurement, integrated water vapor, and dust filter Rich man-machine interface Large-capacity data storage function, supports multiple storage methods High-temperature gas detection (optional) Three display modes can be switched Graphic display Data recovery function Can set to display the maximum, minimum, and average values. Standard USB charging, with a charging protection function, supports USB Using 4500 mA large capacity rechargeable polymer battery High-precision temperature and humidity measurement (optional). Support real-time detection or timing detection Multiple alarm methods, a multi-directional three-dimensional indication of alarm Multiple alarm mode settings Mistaken operation recognition function Zero-point automatic tracking, long-term use will not be affected by zero Multi-level calibration of target points to ensure linearity Logging Meet the design requirements of intrinsically safe circuits, anti-static, etc Protection grade reaches IP65, waterproof, dustproof, explosion, etc   Technical Specifications Detection Gas Formaldehyde CH2O Scope Of Detection 0 Ppm To 10 Ppm, 20 Ppm, 50 Ppm, 100 Ppm, 200 Ppm, 500 Ppm, 1000 Ppm, 2000 Ppm, 5000 Ppm Resolution 0.01 Ppm,0.1 Ppm,1 Ppm Detection Principle Electrochemical Principles Detection Method Built-In Pump Suction, Flow Rate 500 Ml Per Min Display Method 2.31-Inch 320 X 240 High-Definition Color Screen Display, 5 Buttons Operation Detection Accuracy ≤±3% FS Linearity ≤±2% Repeatability ≤±2% Alarm Method Sound And Light Alarm, Vibration Alarm, Visual Alarm, Sound And Light Vibration Visual Alarm, Shut Off The Alarm Response Time ≤20 S Recovery Time ≤30 S Power Supply DC 3.6 V Battery Capacity 3.6 V DC, 4500 Ma Large Capacity Rechargeable Polymer Battery, With Overcharge, Over-Discharge, Overvoltage, Overheating, And Short Circuit Protection Functions Humidity Measurement 0% RH To 100% RH, Accuracy 3% RH Data Storage Standard Configuration Of 100,000 Data Capacity, Support History Viewing, Deletion Or Data Export, Free Host Computer Communication Software.
