Description

The RASI 700 BIO is a portable biogas analyser ideal for measuring gas in landfill, biogas, and waste water treatment plants.

The unit can be configured to measure 02, CO2%, CH4%, H2S and additionally H2 and CO to match the needs of the operators working in landfill applications.

In addition, the analyser provides temperature and pressure readings ( differential, gauge and absolute) as standard, and optionally can measure gas flow by using our unique 3 ways straight pitot tube which enable the user to sample and display gas velocity, gas quality and temperature at the same time.

The gas analyser is powered by high efficiency Li-ION rechargeable batteries which ensure a full day of operation with one single charge. Batteries are charged trough standard USB port.

The biogas readings are presented on its large 3.5″ TFT  6 lines colour display.

The RASI700 BIO is equipped as standard with an extensive data logging function and site administration facility with pre-load measurement points such as well ID’s . Up to 16000 data can be stored in the analyser internal memory and exported to SD card for future analysis on a PC. No specific software is required.

The RASI700 BIO is compatible with our new mobile phone app (both IOS and ANDROID devices) which allow to use your phone to save stream data, save data and generate PDF report. The mobile app also provide GPS position

The RASI700 BIO requires only one calibration per year

The unit is supplied as standard with a light carrying case which contain USB charger lead, wall charger, in-car charger, tubing,  manual and a 12 month valid calibration certificate.
