Description

The RASI 700 is currently one of the most used emissions gas analyser (NOx meter) in the UK for servicing, commissioning and testing any type of industrial engines such as, natural gas, landfill, biogas, propane and Diesel engines.
The RASI 700 is light, extremely portable and easy to use with long lasting batteries. Batteries are charged trough MINI USB port. It comes with pre configured specific measurement menus which help the operator to make the right selection depending from the application. It avoid the need to keep changing the configuration of the display depending from the measurement task that an engineer need to carry out.
The Basic Kit is equipped with O2, CO(H2)0-20000 ppm, NO and NO2 measurement cells. The more advanced kits can be equipped with NDIR CH4%, CO2% and H2S (EC) to measure the quality of the fuel Gas. These KITs are particularly suitable for commissioning engineers working on BIOGAS or LANDFILL Gas Engines who require to know the CH4% content during the commissioning phase.
All the RASI700’s measures exhaust gas temperature, back pressure and provide Lamba ( Air Ratio) readings.
Each RASI700 is equipped as standard with Bluetooth communication to work together with our MRU4U mobile app or WIN4U Windows software.

True NOx measurement

The continuous & high fluctuation of the NO2 portion in the engine exhaust requires to make separate measurement of both NO and NO2 to provide accurate “True” NOx values of the engine. Equally important is ensure that the Total NOx is reported in the correct way.
The Environmental Agency requires the operator to report the total NOx in mg/m3, in term of NO2 and corrected for O2% reference.

Free mobile app ( IOS/ANDROID) for remote control, Fisualization & reporting

Work faster and safer with our new MRU4U mobile app with specific engine reporting function. Capture and share data with your colleague in a more efficient way. Turn your smart device into a gas analyser. Leave the analyser in the exhaust and be in front of the screen “ Noxing” and “mapping” the engine. Data are saved under a Job Number and additional information such as Delivery Pressure, Engine Load, CH4% content and Engine condition can be entered to be saved together with the exhaust measurements.

Measurement made easy

The RASI700 smart menu guides step by step trough the whole measurement process to make it easy and safe for the operator. The large 3.5 “ TFT graphic colour display provides information relevant to the application and guides the user through the measurements from start to finish. No instrument-specific knowledge is therefore required. Instrument settings, such as correct O2% reference and display values are activated by selecting the application. User can re-name programme and change setting as required.

Higher CO cell 0-20000 ppm and sensor protection by additional purge pump

All the RASI 700 are now equipped as standard with an higher range CO (H2 comp) measurement cell which is able to with-stand CO concentration up to 20000 ppm with-out any dilution. The new cell also have an enhanced NO filter. In addition to this each RASI700 is equipped as standard with a CO purge pump which will protect the cell and prevent saturation from unexpected high CO level.

Special Engine Gas Sampling probe

Each RASI 700 is supplied with a sampling probe which is especially designed for optimal use on engines exhaust measurements. The probe is supplied with a replaceable tip , 365 mm made in stainless Steel with an operating temperature up to 850 °C and 2.7 m Viton sampling line to prevent NO2 abortion. Thanks to the COAX design, integrated type K thermocouple and triple hose, the RASI 700 provides gas,  temperature and back pressure measurement at the same time
