The 'AGA' Mini-test is designed for testing proper function in the field; without need of complex, expensive test instruments.
The Mini-test is suitable for use with the following, Interspiro marques:
Complete with instructions, the kit is easily used by divers and fire-fighters to adjust or check:
In fact, this little box enables skilled operatives to make field adjustment*, testing all relevant areas of performance to 'the book'; whilst, given a few minutes training, those who are not technicians can easily check the equipment is working to parameters laid down in user hand-books.
Small enough to fit the technician's work case, this is an invaluable addition to his standard kit, which is likely only to offer static, rather than dynamic results.
* It should be noted that the Mini-test is designed primarlily to give 'go/no-go' indications, the water bottle and tube acting as a crude manometer; the weighted end kept close to the bottle bottom. Relatively accurate manometer readings may be taken, if technicians mark the dip-tube in millimetres - each graduation therefore representing 10 Pa, read from the upper water meniscus to the meniscus mark in the dip-tube.
Our own, field technicians attach a graduated rule to the dip-tube, so that pressure differences may be read to within +/- 1mm water gauge (+/- 10 Pa). Thus, readings are obtained, with care, that permit testing adjustments to within the specifications laid down in approved service manuals.
