EGA41
Portable bench top CO2, H2O and O2 analyzer
Affordable, portable, bench-top, triple gas analyzer with integral data logging to SD memory card. The system measures CO2 to 1ppm in a range of 0-2000ppm, and H20 to 1% relative humidity in a range of 0-100% relative humidity and O2 to 0.1% or 1,000ppm in a range from 0-100%. Designed for temporary versatile applications, It can be used at remote locations with a 12 volt car battery.
Features
- Instrument zero calibration happens with every measurement
- Integral sample pump with adjustable flow rate
- Auto logging to removable SD memory card
- 7 analog inputs for external sensors
- USB and analog output
The EGA41 features a temperature compensated infrared gas analyzer, ensuring stability over a wide range of operating temperatures. The Infra-red gas analyzer features a low loss, gold plated analysis cell to ensure a low noise, high output signal from the detector. Oxygen is measured by a dual thermally compensated, high accuracy electro-galvanic fuel cell.
H2O measurement is by the latest technology, laser trimmed sensors.
All readings are automatically compensated for changes in atmospheric pressure.
The EGA41 has a long life sample pump which is designed to give many years of service. The integral soda lime column is used to auto zero the infra-red gas analyzer, ensuring long-term stability of CO2 calibration.
The storage capacity of the supplied 2Gb, SD memory card provides enough space for hundreds of thousands of data sets.
Data storage can be initiated by a high signal on the CTS line of the RS232, when an analogue input gets to a particular level, after one of the relays actuates or at timed intervals.
Data download can be via the high speed USB port or the SD memory card can be removed and plugged into a card reader or a suitable memory card slot on a PC.
All data is stored in an ASCII comma separated variable (.csv) format.
Gas readings, flow indication, power supply status and date and time are all displayed on the large, LED backlit LCD display.
