Macurco GD-6 WHITE Combustible Gas Detector, Controller and Transducer, 12-24VAC or 12-48VDC, White Housing

The GD-6 is a versatile, easy-to-use device that allows you to select between methane, propane or hydrogen gas detection. Combustible gas detectors will respond to a wide range of hydrocarbons, including aerosol sprays, cleaning solvents, paint thinner and other common volatile organic compounds. This low voltage detector provides automatic feedback and fan or valve control that can help reduce combustible gas concentrations in parking garages, battery rooms, maintenance facilities, and other locations that require combustible gas detection.

Features

• White housing
• 12-24VAC or 12-48VDC input
• Alarm relay is activated if gas reaches or exceeds the alarm settings
• Low level meter capable of displaying from 0-50% LEL EX Display, Control & Calibration
• Selectable (on/off) digital display, buzzer, fan delay minutes), fan minimum run time
