Duran Electronica STANDGAS HC

Duran Electronica STANDGAS HC
The STANDGAS PRO LCD Exp is a stand-alone detector designed to detect explosive gases using catalytic technology (pellistor). It offers a detection range of 0 to 100% L.E.L and is resistant to silicone vapors (HDMS). This detector is available in a special version with three programmable relay outputs for added functionality.

Duran Electronica STANDGAS HC Key Features:

• Standalone Functionality: Operates independently without the need for a control panel.
• Optical Indicator: Provides clear visual indicators for operational status and sensor faults.
• Gas Selection: Allows selection of the gas to be detected via a jumper.
• Programmable Relay: Set the initial status for the alarm relay and program up to three alarm levels in the special version, or two levels with a fault output.
• Programmable Alarm Activation Delay: Offers configurable activation delay for the alarm relay (fixed in the special version).
• IP65 Protection Grade: Ensures durability and protection in various environments.
• Silicone Vapor Resistance: Resistant to interference from silicone vapors, enhancing reliability.

Detection Range:

• 0 to 100% L.E.L (Lower Explosive Limit).
