1. INTRODUCTION
The GrainPro®Carbon Dioxide Analyzer (CO2Analyzer) is a microprocessor-based instrument
used for the detection of %CO2(Carbon Dioxide) and uses an NDIR (Nondispersive Infrared) sensor for
measuring CO2levels range of 0 to 80% CO2content. With a microprocessor-based unit, it has a data logging
facility and can store data in real time which can be downloaded into a computer.
When an NDIR sensor encounters CO2, a voltage signal is generated in proportion to the gas
concentration. This voltage signal is amplified, digitized, and displayed on the instrument’s OLED (Organic
Light-emitting Diode) display.
The CO2Analyzer has the following important parts: gas sensor, signal conditioning electronic circuit,
microprocessor board, digital display, a sampling pump and a battery pack. It is powered by a 7.4V Li-ion
rechargeable battery.
1.1. FEATURES:
1.1.1. Portable.
1.1.2. More than 5 years sensor expected life span.
1.1.3. Backlit 20 x 4 Alphanumeric OLED display.
1.1.4. Microprocessor-based instrument, it can log and download data on a computer.
1.1.5. Data logging capability for up to 3000 samples.
1.1.6. Records gas readings along with time/date.
1.1.7. Rechargeable battery pack.
1.1.8. Low battery indicator.
1.1.9. Enclosed in high temperature resistant plastic.
1.1.10. Includes USB cable for PC connectivity.
1.1.11. Sampling tube with dust filter.
1.1.12. Alarm with audio and visual LED display.
1.2. PRODUCT GUARANTEE:
1.2.1. In accordance with the terms and conditions herewith, GrainPro Inc. fully guarantees the quality
