GasEye Extractive HCHO
Formaldehyde ANALYZER
GasEye HCHO is a high performance formaldehyde analyzer. Suitable for safety applications and process control. 24/7 continuous operation. No sample preparation. No zero drift. No field calibration. Low cost of ownership.
Features
- HCHO ranges: 0 – 1 ppmv / 0 – 100 ppmv
- Process temperature: 0 – 100°C
- Real time sensing: response time below 0.1 second
- High selectivity: automatic compensation for interference effect from other constituents in the gas sample
- High sensitivity: detection limit below 0.2 ppmv
- Maintenance free: equipped with a self-calibrating feature, no field calibration necessary
- Robustness: IP66 enclosure, suitable for outdoor and indoor installations and harsh environments
- ATEX version available

Technical specification
Outputs: | 4 x analog output 4 – 20 mA (gas concentration, process transmission, 2 x AUX) – easy user selection via DIP switch between active/passive mode |
8 x digital output (NAMUR) | |
Inputs: | 4 x analog input 4 – 20 mA (process temperature and pressure) – easy user selection via DIP switch between active/passive mode |
1 x RTD (PT100/PT1000) - easy user selection via DIP switch between PT100/PT1000 and 2-/3-/4-wires | |
8 x digital input | |
Local User Interface: | Human Machine Interface (HMI) - LCD backlight display located on the transmitter housing lid |
Ethernet port: a) WebServer – system configuration and data acquisition via web browser, b) Windows based program – GasEye logger for real-time data acquisition, c) remote service and diagnostics |
|
Optional: | Modbus (TCP/IP), Modbus RTU, Profinet, Profibus |
Power input: | 230 VAC nominal (100 – 240 VAC) |
Power consumption: | < 300VA (< 400VA if ATEX) |
Automatic gain control (AGC): | AGC ensures correct gas measurement even at high dust loads resulting in loss of optical transmission down to 0.5%. AGC operates fully automatic with no need for manual adjustment of the signal gain under any process conditions. |
Self-calibration features: | Internal reference gas compartment is used for closed loop control of the zero and span drift |

GasEye Extractive Wall Mounted type analyzer exists in general purpose and hazardous area configuration (version Ex1). It exists in several various configurations from single gas to multi gas applications. The system is IP66 rated with ambient temperature ranges from -30ºC to +60ºC and can be mounted outside without a need for a container.
GasEye Extractive Ex1 provides Ex p (purge and pressurization) type of explosion protection. Ex p pressurized equipment is the technique of guarding against ingress of the external atmosphere into an enclosure by maintaining a protective gas therein at a pressure above that of the external atmosphere. The overpressure is maintained either with or without a continuous flow of the protective gas.
