GDS FEATURED PRODUCT
SINGLE / DUAL CHANNEL GAS MONITOR
The new GASMAX CX Gas Monitor features a stunning full color display and advanced networking features for next generation gas detection applications. Designed especially for situations where gas readings need to be digitally transmitted across networks, the GASMAX CX features standard 10/100 Ethernet and optional dual MODBUS ports with data rates to 115 kbps in addition to traditional dual 4-20mA analog outputs. The high performance microprocessor hosts a MODBUS/TCP database and integrated web server that allows remote users to monitor gas levels or make configuration changes in real time via any connected personal computer, smart phone or tablet device.
The full color back lit TFT display is easy to read and changes to high-visibility yellow or bright red in the event of gas alarms. Optional alarm relays make it easy to directly attach warning strobes or horn sounders. Magnetic switches that surround the display allows users to calibrate or configure the GASMAX CX without opening the cover or declassifying the area.
The GASMAX CX is CSA certified for use in Class I Division 1 hazardous areas.
