Portable sludge interface level meter


Portable meter for sludge interface level Mod.HANDY 7900

Designed for spot measurements of the interface sludge level in sedimentation basins, it is suitable for the use in wwtp and in all those process where sedimentation basins are used.   This analyser is composed of an immersion probe, an electronic unit and a connecting cable.
The immersion probe is an optical sensor including IR light source and IR light receiver (positioned at an angle of 180° from each other).     The probe is made of PVDF and is very sturdy;  the cable is sealed into the probe and cable outlet is from watertight cable gland: so forth the probe can be immersed down to 5 m; the special reinforced cable-to-probe connection assures great  protection against all possible mechanical stresses due to immersion and lifting of the probe operated using the cable.  For this purpose the polyurethane cable, length 6 meters,  is internally Kevlar reinforced.
The portable electronic unit   is very sturdy and  handy; it includes a slide switch for power ON and power OFF, a trimmer for the sensitivity adjustment, a LED and a buzzer for the indication of the sludge interface level.
Power supply is from rechargeable battery,  8,4 V, 170 mA/h (average autonomy is 1h 15min with lit display). The instrument accepts a 12 VDC auxiliary power supply (rear connector) that is also used to charge the battery.
The analyser is supplied c/w a properly dimensioned  carrying case  with waist belt including  fixing strips for the probe and for the cable.   This system leaves the operator hands free while he moves to reach the measuring position.  The electronic unit can be used directly inside the case so that during measures  it is fixed on the operator waist belt, therefore the operator has always a hand free during the measure.
Operating temperature limits are 5 to 50 °C, with relative humidity 0-90% non condensing.
The analyser is factory calibrated.   Before each the use connect the probe and adjust sensitivity if required.
