Introduction

AM4202 Series is focused on NDIR refrigerant gas sensor that offers industrial grade accurate and reliable detection of A2L gases (including R32, R454A, R454B and R454C), and A3 gas R290.

Based on NDIR (Non-Dispersive Infrared) technology, AM4202 Series could detect and monitor refrigerant gas leakage and provide early warning. It has the advantages of fast response, excellent accuracy and good long-term stability. Full auto baseline calibration mechanism also secure free of maintenance during its life span.

To adapt for industrial and commercial multi-drop communication application, AM4202 Series is extended with 12/24 VDC power supply, RS485 and Modbus communication. It could fulfill more efficient integration with industrial refrigerant monitoring systems.
