Product Overview
The RL-B500 type natural gas calorific value analyzer is a high-precision online gas detection and analysis instrument developed by our company. This instrument adopts imported sensors combined with single-chip microcomputer control technology, featuring high measurement accuracy and simple operation;
The instrument uses high-performance embedded integrated touch screen, TFT color display, which can simultaneously display measurement values, historical curves, range, status, and various parameter settings interface;
Full Chinese touch menu or remote control form is used for configuring, calibrating, testing various instrument parameters, and historical records, curves can be set according to time;
The new gas path flow stabilization system: has technical, high precision, fast response, stable performance, continuous gas analysis process advantages;
It is widely used in high-temperature furnaces, converters, coke ovens, etc. for gas, galvanizing lines, coal and cement sites, petrochemicals, calcium carbide furnaces, liquefied natural gas, metallurgy, electronics and power, environmental protection, etc.
