Water Sensor
–
Parts Per Million (PPM)
The PPM option incorporates a water moisture sensor into the fluid circuit of the portable analyser.
The sensor offers real time measurement of absolute water content in ppm (parts per million) and
outputs a value up to the fluids saturation point.
As per BS EN 590 diesel fuel should contain no more than 200ppm (0.02%) of water.
The sensor is calibrated specifically for use with diesel fuel, use with other fluid types will provide
inaccurate readings.
Note: If the fluid sample contains free water or has a water content of above 300ppm (cloudy/hazy
appearance) it should not be passed through the portable analyser. Samples above 300ppm will
cause the sensor to lock out. If this occurs, clean dry diesel (<100ppm) will need to be flushed
through the unit for 15 minutes to 2 hours (depending on level of exposure), where the readings will
gradually fall back within its normal operating range.
