GS-300 Series Gas Detectors
HVAC-R, Commercial and Light Industry Application
The GS-300 gas leak detector line is designed to address a wide array of HVAC-R applications in commercial and light industrial environments. It features a selection of fixed point detectors available for combustible, toxic, refrigerant gasses, as well as Oxygen level monitoring.
GS-300 detectors are engineered to function seamlessly as a streamlined autonomous solution or a reliable field-level element of our advanced analogue and addressable systems. They are available with a current (4-20mA) or digital (Modbus RTU) output configurations, with optional integrated relays.
The detectors are simple to install and maintain. The high-visibility light indication allows for easy status monitoring, while their one-person, non-intrusive calibration feature and solderless sensor replacement facilitate maintenance and eliminate the need for system downtime. All GS-300 detectors are equipped with a self-diagnostic function, which constantly monitors the condition of the sensor and signal lines, and alerts in case of fault.
Benefits:
Versatility: The wide variety of available gases and output options (4-20mA, Modbus RTU, Relays) make the GS-300 series a perfect solution for diverse HVAC-R projects from boiler rooms to underground parking.
Cost-effective specification: GS-300 detectors are designed to deliver maximum value and reliability. With a low initial investment, they effectively reduce project costs. Additionaly, the non-intrusive calibration feature, solderless sensor replacement option and self-monitoring technology streamline the maintenance process and result in substantial savings.
