The Micro2 is a minature hand held battery operated portable oxygen monitor. It measures oxygen concentration using a long life electro-chemical sensor, which is remote to the display. Oxygen concentration is displayed on a high contrast LCD display with a resolution of 0.1% oxygen. The Micro2 is simple to use and will power down automatically to increase battery life, with a battery condition indicator indicating when the battery needs replacing. Possible applications Checking of pre-mixed gases in diving and other critical applications. Inert gas purge checking in welding applications. Spot checks of ambient oxygen concentrations in areas where oxygen deficency or enrichment are likely. Checking the operation of oxygen concentrators and inert gas generators. Features Resolution 0.1% oxygen Accuracy 1% Fast response temperature compensated sensor. Simple calibration in air by means of shrouded trim pot located at side of unit, alleviating accidental adjustment whilst still giving the operator access to calibrate. Impact resistant 'pocket sized' case sealed to IP55. Uses 1 x PP3 9V Alkaline battery ( Integral battery compartment ) Low battery Voltage indication.
