Gas Detectors & Sensors
CETCI - cGas Detector Digital Transmitter
The cGas Detector is a digital, one or two channel gas detection transmitter that offers greater flexibility at a lower cost with customized sensor combinations and specialized options for adding only the functionality you need. It is ideal for monitoring toxic, combustible and refrigerant gases in commercial and light industrial, non-hazardous (non-explosion rated) environments. Output is user selectable in the field with your choice of BACnet® or Modbus® for communicating with a Controller or a Building Automation System. Pre-calibrated sensors with true Plug & Play Smart Sensor technology makes replacing sensors quick and easy.
CETCI - cGas Detector Analog Transmitter
The cGas Detector Analog Transmitter is a low maintenance gas monitoring device designed for use in non-explosion rated, commercial applications and is ideal for monitoring toxic, combustible and refrigerant gases. Powered by 24 VDC or ground referenced AC, the cGas Detector has an LCD display, temperature compensation and the firmware and configuration can be upgraded in the field using the USB connection. Pre-calibrated sensors with true Plug & Play Smart Sensor technology makes replacing sensors quick and easy. The cGas Detector comes in a standard water / dust tight, corrosion resistant ABS/ polycarbonate enclosure with a hinged, secured door. With the optional, factory installed splash guard the enclosure is IP54 rated and provides protection in water spray or wash down applications.
CETCI - cGas Detector IR Refrigerant Transmitter
The cGas Detector IR Refrigerant provides continuous monitoring of a wide range of refrigerant gases commonly used in commercial refrigeration systems. Dual beam, non-dispersive infrared sensor technology overcomes the limitations of solid state refrigerant sensors, accurately detects refrigerant gases without cross interference from toxic or combustible gases and is low maintenance with a longer lifespan. Choose from many types of refrigerant gas sensors commonly used in commercial refrigeration systems, including A2L refrigerants, SF6 and CO2 (R744). True Plug & Play Smart Sensor technology makes replacing sensors quick and easy.
Gas Detection System Controllers
CETCI - Multi Channel System Controllers
The FCS Flexible Control System is a sophisticated, high performance controller that offers multi-channel configurations for monitoring toxic, combustible and refrigerant gases with versatile control functionality for non-hazardous, non-explosion rated, commercial and light industrial applications. The FCS is designed to accept inputs from digital and/or analog transmitters and/or Peripheral Devices (in various combinations), using Modbus® RTU RS-485 or 4-20 mA analog input. The FCS is available in 4 channel, 8 channel, 32 channel and 128 channel models with either Modbus® RTU RS-485 WAN output or with BACnet® MS/TP RS-485 WAN output for communicating with a Building Automation System (BAS).
CETCI - Self-Contained Controller
The CGAS-SC Self-Contained Controller is a versatile gas detector that offers up to 3 channels for monitoring toxic, combustible and refrigerant gases in commercial and light industrial, non-hazardous (non-explosion rated) environments. It can be used as a standalone monitoring device or part of a larger gas detection system. It accepts 4-20 mA analog inputs and all models feature field configurable BACnet® or Modbus® output for communicating with a controller or a BAS. Sensor configurations include combinations of internal and/or remote sensors, including 3 remote or 1 internal + 2 remote sensors. Plug & Play Smart Sensor technology makes replacing the pre-calibrated sensors quick and easy.
CGAS Detector for Public Spaces
The cGas Detector is designed for use in publicly occupied spaces where integrated demand controlled ventilation (DCV) is used; for continuous monitoring of refrigerants where high-efficiency, high volume refrigerant cooling and heating systems (VRF) are used; and for other continuous monitoring of hazardous gases in publicly frequented areas. Both the analog and digital models are powered by 24 VDC or ground referenced AC, come with an LCD display, temperature compensation and thermal resetting fuse. Sensor replacement is easy with true Plug & Play smart sensors that arrive pre-calibrated. The firmware and configuration can be upgraded in the field using the USB connection. The digital models are user configurable in the field for BACnet® MS-TP RS-485 or Modbus® RTU RS-485 output for communicating with a controller, Building Automation System or other control panel.IAQ Gas Detectors
YESAIR 8 Channel IAQ Monitor
The YESAIR is a battery powered, portable air quality detection and data logging instrument designed for intermittent or continuous indoor air quality monitoring of temperature, RH, particulates and up to 5 gases. It is available in two models (Pump or Diffusion). Each can be configured as a multi-channel operation, with a selection of more than 30 different plug and play gas sensors, including a particulate sensor and an optional huge capacity data logging SD memory card. Both models come with one temperature sensor, one relative humidity (RH) sensor and the capacity for 5 internal gas sensors consisting of a maximum of three electrochemical toxic gas or oxygen sensors plus two high current draw sensors such as an infrared, PID, catalytic or particulate sensor. Sensor readings, battery level and data logging status can be viewed live on the multi-line, backlit, LCD display.
YES Plus LGA 15 Channel IAQ Monitor
YES Plus LGA is a multi-gas air quality monitoring and information recording instrument that simultaneously measures and records up to fifteen sensors including RH and temperature. The large, backlit, multi-line scrolling LCD display indicates the sensor types installed and measured values for each gas, battery status and more. The system utilizes a long life rechargeable NiMH battery pack providing more than 24-hours of run time, depending on sensor array installed. The user can also set one alarm level for each gas to activate the internal audible alarm. The system is housed in a rugged ABS enclosure with swivel handle to act as a stand support or for carrying the instrument.Fixed Gas Detectors
ART Infrared Refrigerant Transmitter
The ART is a single channel, non-dispersive infrared refrigerant gas detector with a display and relay that can be used as a stand alone system or integrated into a building management system (BMS). The fast responding infrared sensor accurately detects refrigerant gas leaks without cross interference from toxic or combustible gases, minimizing false alarms. It offers Modbus® output to a BAS and may be connected as an analog transmitter or a Modbus® transmitter. The ART is compatible with the FCS (analog or digital) and the DCC (analog).
