6401-0500 MGS-250, Infrared Halocarbon Detector, Broadband by Bacharach

Bacharach's new MGS-250 Infrared Refrigerant Gas Transmitter is the leader in performance and flexibility at an economical price. There are two versions available - a cost-effective broadband sensor used for gross leak detection or gas-particular versions that are even more distinct, pre-calibrated and characterized for response to specific refrigerants. Its simple-to-use interface gives the user the ability to set all parameters and outputs without opening the unit, moving jumpers, using mulitmeters or adjusting potentiometers.

The MGS-250 family is a cost effective solution for detecting a variety of refrigerants without the limitations posed by solid-state sensor technologies. The long-life, proprietary NDIR infrared sensor allows for accurate low-level leak detection (0-3,500 ppm), delivering up to 5-7 years of maintenance-free operation without the need for costly annual gas calibrations. Infrared sensing technology makes the MGS-250 immune to cross sensitivities to combustible and toxic gas as well as changes in temperature and humidity. The unit has an alpha-numeric LED display to show constant real-time readings, an on-board LED indicator for when the sensor is in an alarm state, and an audible alarm to alert personnel in the area that levels have exceeded the desired limit. An optional protective splash guard is available for use in areas with high water spray such as food and beverage facilities or chiller rooms.

Features & Benefits:

• Long-life, Non-Dispersive Infrared (NDIR) sensor allows for accurate low-level leak detection
• Detects all refrigerants (CFC, HFCs, HCFC, HFO's), including HFO1234YF, HFO1234ZE, R410a & R22
• Fast-responding, refrigerant-specific sensor with no cross interferences to other gases
• No field calibrations required
• Modbus RTU interface to connect to BAS/BMS systems and on-board alarm relay
• User selectable analog output: 4-20 mA, 0-5V, 1-5V, 0-10V, 2-10V
• Bright, alpha-numeric LED real-time display with on-board audible and visual alarms

5917-0300 GDC-350 Gas Sensor Monitor, NEMA 1 Housing, O2 Sensor w/ Pre-wired Supply by Bacharach

Bacharach's all new GDC-350 full-featured fixed gas monitors provide superior operation - standalone or as part of a larger system utilizing the standard analog outputs. This state-of-the-art instrument can detect a wide range of gases including carbon monoxide (CO), oxygen (O2), combustible gases, refrigerants and total volatile organic compounds (TVOCs). The GDC-350 provides a unique two sensor interface, allowing for multiple gases to be detected with onboard or remote sensors. Sensors can be located integral to the unit or remotely allowing for sensors to be placed directly in areas where potential leaks can occur. Bacharach s proprietary calibration algorithms extend the amount of time required between calibrations, reducing maintenance costs and lowering the overall cost of ownership for non-critical applications.

The GDC-350 has all the features and functionality for any application. LED alarm indicators visually indicate when alarm conditions are met and an audible alarm alerts nearby personnel. An onboard alpha numeric display shows gas readings in real time for each sensor. Integral dry contact relays are available to drive external audible / visual alarms, activate fans, or connect to building management and control systems. Installation and maintenance is simple and easy, reducing overall system cost. A pre-wired plug-in option is available for out-of-the-box operation. Simply plug the unit into any standard AC outlet for immediate detection and protection.
