PORTABLE GAS DETECTOR
The portable toxic gas or combustible gases detector with audiol/visual alarms and meter display is ideal for confined space monitoring. The detector is compact, light weight, and battery operated. With built-in charger and Ni-Cad batteries allows the unit 10 hours of continuous operation. The hand held probe with the sensor (no mechanical pump) and 5 feet of wire provides local area gas measuring. Analog meter, or 4-digit large LCD digital display indicates PPM or % LEL. Shoulder held carrying case and instrument case are also included. 0-1 VDC output for data acquisition is optional.

WALL-MOUNT GAS DETECTOR / MONITOR
The wall-mount toxic gas or combustible gases detector with audio/visual alarms and relay contacts provides continuous open/enclose space monitoring. The basic unit has a detecting sensor and controller joining together. If necessary, remote sensor with explosion-proof junction box housing and 50 feet cable wire (longer length can be extended to 600 feet) connection are also available. The explosion proof sensor and housing are ideal for hazardous area monitoring and meet NEC requirements for Class I, Division I, Group A-B-C-D. All the models can provide either 4-20mA or 0-1 VDC output for data acquisition purpose, and PLC interfacing. Analog Meter indicates PPM or % LEL. Digital display use large Red LED is also available.

SINGLE AND MULTI-CHANNEL GAS MONITOR/ALARM IN NEMA-4 ENCLOSURE
The gas monitor includes remote sensor(s) and controller in NEMA-4 enclosure for indoor, or outdoor installation. Each sensor with explosion-proof junction box housing and 50 feet cable wire connects to the controller. Each channel operates independently and indicates the concerned gas level at differnt sites and can be seen instantly. Standard individual channel has Power GREEN LED, Alarm RED LED, Fail (Malfunction) YELLOW LED, and Meter display (PPM or % LEL). Basic unit has individual module, master module, and power module. This design gives easy operation and replacement, if necessary.

SENSOR DATA TRANSMITTER (SDT) GAS DETECTOR
The Sensor Data Transmitter (SDT) detects the toxic gas, or combustible gases and indicates the concerned gas level with 4-digits Red LED PPM or % LEL. The SDT stands alone monitoring the dangerous gases/vapors with explosion-proof sensor and housing. The housing has a glass window, which you can see through the bright red digits in dark or light areas. The unit provides linear 4-20mA output for data logger and recorder. the SDT operates on 12 VDC power supply. It's also available for 24 VDC or 115/220VAC power. It can be installed at hazardous areas and meets NEC requirements for Class I, Division I, Group B, C, D.
