HANDY 3000 -gb
Portable analyser for Oxygen in air Mod.HANDY 3000
Designed for the measure of oxygen in air and suitable for the use in plants using nitrogen, liquid or gas, and other gases (non incendive) that may cause oxygen depletion in ambient air. In these cases the measure of the oxygen concentration in ambient air is a safety requirement for the health of the operators. This analyser is composed of a probe, an electronic unit and a connecting cable.
The probe includes a 2 electrodes galvanic cell, with good sensitivity and fast response time.
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; the special reinforced cable-to-probe connection assures great protection against all possible mechanical stresses due to positioning of the probe operated using the cable. For this purpose the polyurethane cable, length 6 meters, is internally Kevlar reinforced.
The portable, microprocessor based, electronic unit is very sturdy and handy, has a wide, good visibility, OLED display and a watertight membrane keypad. The instrument receives the O2 and temperature signal from the probe, operates the temperature compensation of the measure and displays O2 value and air temperature.
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.
Measuring range is 0-20,000 ppm with 1 ppb resolution and ± 5 ppb accuracy The instruction manual includes tables for the conversion “ppm value to O2 % value”.
Operating temperature limits are 5 to 50 °C, with relative humidity 0-90% non condensing.
The weight of probe with integral cable is approx 600 g; the electronic unit weights approx. 350 g; probe dimensions are 42 mm diameter, 240 mm length; electronic unit: 48x96x100 mm.
The analyser is factory calibrated. Zero calibration is usually never required, however the instrument includes a dual point calibration procedure, zero point is calibrated in a nirtrogen flow (a calibration vessel is supplied) while the slope is very easily calibrated in air (in well aerated room or outdoor).
