Wireless Industrial Gas Monitor Configurable SensorsElectrochemical Gas Sensor
WOOFAA Cee industrial gas monitor is using solid-state electrochemical gas sensors, which not only giving a higher measuring range and resolution on PPB level, it also has a much long er (5-10 years) product life versus conventional type (1-3 years), with a price tag of nearly 70% off.
Deployment in Smart Carpark can automatically and safely reduce ventilation energy saving up to 30%.
The magic is on and advanced high polymer technology from Germany, with which the conventional liquid-state electrochemical sensor method is replaced by solid-state. This advanced tech brings in advantages such as:
- Industrial grade precision (accuracy, repeatability & linearity), superior performance above all semiconductive and MEMS type sensors
- PPB (parts-per-billion) resolution, against to PPM (parts-per-million) on semiconductive and MEMS type sensors
- Less data drifting over time, no calibration is ever needed over its product life
- Faster response time, quicker zero recovery, no warm-up time due to its low temperature resistance
- Immunes towards electromagnetic interference, resulting a lower-cost hardware construction to work with AC power supply and WIFI signals on the same PC board
- Works well in very dry ambient, as the high polymer file is insensitive to humidity changes
- Works well in vacuum or anoxic ambient
- Compact size
- One-third or one-fourth of price to conventional liquid-state electrochemical type sensors
- Compliance:
- RoHS
- EMC: EN55022 and FCC
- EU 2002/231/CE Directive
- EN 13779:2007
- GB 12358:2006
- GB 50325:2010
- GB 3095:1996
- GB/T 18883:2002
- TW Indoor Air Quality Standards
Excellent data consistency and linearity across multiple industrial gas type, in high polymer solid-state electrochemical sensor adopted in WOOFAA Cee

HKCITTC is a vocational training center for construction workers. Apart from general IAQ wireless monitoring (on PM2.5, VOC, Room Temperature and Relativity Humidity), there are few welding zones where the management wanted to monitor two specific types of industrial gas for safety purpose: carbon monoxide (CO) and acetylene (C2H2).
Conventional industrial grade CO and C2H2 gas detectors are expensive and bulky if made to work wirelessly. Our WOOFAA Cee made an excellent alternative hardware in terms of both performance and time to deployment.
