N-Methylpyrrolidone NMP Gas Alarm

Product Overview

The N-Methylpyrrolidone NMP gas alarm developed and produced by Besian adopts a diffusion method to convert the gas concentration signal at the monitoring point into an electrical signal in real time. This signal is amplified and then processed by the CPU via AD sampling, temperature compensation, and intelligent calculation. If the measured value exceeds the set alarm concentration, an alarm signal is issued.

The BSA/QT-BJ series intelligent gas alarm features advanced technology, excellent performance, high stability, compatibility with multiple signal outputs, and convenient installation and maintenance, greatly meeting the requirements for high reliability of equipment in industrial safety monitoring.
