Key Features

• Using imported thermal conductivity sensors, combined with single-chip microcomputer control technology, it forms a product with high measurement accuracy and simple operation.
• 128*64 LCD display, intuitive display, simple and convenient operation;
• Long service life, high accuracy, fast response;
• Built-in insulation device to reduce the influence of sample gas temperature and environmental changes on measurement accuracy;
• Automatic timing storage function, allowing for immediate data viewing;
• Alarm points can be set arbitrarily within the full range;
• The instrument adopts full Chinese menu operation, easy to understand, simple and reliable, with control contact output, self-alarm when exceeding limits (beep), and can be freely set control mode;
• Standard 4-20mA current output and RS-232 or RS-485 (selectable one) external ports;
• When there is no operator, it can record hydrogen content at regular intervals, and can store up to 3000 data.
• When the hydrogen content in the measured sample gas reaches the set alarm point, the instrument will automatically alarm.
• Using a new type of gas path flow stabilization system; it has the advantages of high technology, high accuracy, fast response, stable performance, complete functions, convenient operation, continuous gas analysis process, etc.;
• It is widely used in some occasions that require the detection of hydrogen (argon, carbon dioxide) content in industries such as petroleum, chemical industry, metallurgy, and power.
