The E2638-LEL is a combustible gas detector-transmitter designed for industrial safety monitoring. This device detects various hydrocarbon gases such as hydrogen, methane, propane, butane, and others with high accuracy. Equipped with a MOS or Pellistor sensor, this device offers fast response, long sensor life, and installation flexibility with either a built-in sensor or remote probe. With analog and digital (RS485 Modbus) interfaces, relay options, and LCD indicator options, the E2638-LEL prov
