GAOTek Automatic CO2 Gas Analyzer

Description Features Using imported high-precision Infrared principles sensor LCD dot matrix display technology Support Chinese and English operation interface, easy to switch Gas concentration unit PPM, mg per m3 can quickly switch display Built-in micro sampling pump, the pump suction size ten stalls adjustable Explosion-proof certification, proof grade: Exia II CT4   Technical Specifications Gas Detected CO2 CH4 NH3 CH2O C6H6 C7H8 C2H4O Detection Principle CH4: Catalytic combustion principles C6H6 C7H8: Semiconductor Inspection Principles C2H4O NH3 CH2O: Electrochemical principles Resolution 0.01% lel, 0.01 PPM Measure Range CH4: 0 % LEL to 100% LEL, NH3 C7H8 C2H4O C6H6 CH2O: 0 PPM to 100 PPM Sampling Method Built-in stable flow pump, each flow pump is equipped in each independent module, pump flow is adjustable in ten steps, flow range: 0 mL per Min to 800 mL per Min Modular Structure 3 detection modules, each module can be selected to detect up to 6 kinds of gases, and a total of 18 kinds of gases can be selected. The independence between the modules can solve the problem of mutual interference between gases to the greatest extent. Concentration Unit ppm, mg per m3, % VOL, % LEL, can be switched by one button, and the concentration value is automatically converted by the internal system Display 3.5-inch color display, resolution 320 x 480 Display Content Gas formula, concentration data, unit of measure, gas curve trend, battery level, time, temperature, humidity, pressure (optional), pump status, wireless status, printer status, screen capture status Display Mode Multiple display modes selectable, multi-channel data mode, multi-curve mode, multi-channel data multi-curve mode, single channel single curve mode Humidity humidity: 0% RH to 99% RH, resolution: 1 % RH (optional) Data Storage Standard 8G SD card storage function (more capacity can be customized), storage interval can be set by itself, can achieve local storage, view, delete historical data and alarm records, can be directly connected to the computer through USB, quickly download stored data, TXT document; with PC software to download, store, analyze, print data Communication And Data Download Output RS232, RS485 signal; with PC software to download, store, analyze, print data (optional) Wireless Transmission Bluetooth (with printer), ZigBee, built-in DTU wireless module (optional) Print Built-in printer or external Bluetooth printer (optional) Print Content Text, graphics, 1D code, 2D code, curve Screen Capture Settings The content displayed by the current host can be saved in the form of a BMP picture, and then the picture is exported to the computer through the USB cable for the user to record and reference. Operating Language Chinese and English Battery Capacity 3.7 V DC, 10000 mA rechargeable polymer battery with overcharge, over discharge, over voltage, short circuit protection Charging Interface Micro USB charging interface is designed to be charged anytime, anywhere with common data lines and mobile power Filter Device Each module is equipped with a multiple layer filter to efficiently filter oil, water, and dust.
