Potatest Specifications
Microbiological Testing is carried out by using a Single Incubator for the analysis of Faecal and Total Coliforms (switchable 44ºC & 37ºC, accuracy 0.5 deg C). Temperature measurement is with a spirit thermometer. 18 re-useable Aluminium Petri Dishes are supplied as standard. 12v DC power supply to incubator is via an integral 230v AC mains adapter/battery charger, plus electrical lead for 12v DC operation via vehicle dash-board cigarette lighter, and crocodile lead for use with rechargeable battery. Includes specially designed incubator calibration kit.

The Membrane Filtration Unit is supplied complete with Collection Flask, Sampling Cup and Land Line plus Bronze Disc,
Gaskets and O-Rings, and a Vacuum Pump. 200 Pads and Membranes are also supplied as standard with a Pad Dispenser, 38.1g Membrane Lauryl Sulphate Broth for 200 Bacteriological Tests (Faecal and Total Coliforms), 5 no Media Measuring Device (MMD) for the accurate measurement of dried media required for 10 tests. Tweezers, 5 Dropping Pipettes, 2 Plastic Bottles, Hand Lens, Pen, and a tube of Lubrication Grease.

Physico-Chemical Testing is carried out by using a Pocket pH Meter, and a 3-part Turbidity Tube for measuring over the range 5-500JTU. The Potatest also includes a Colour Comparator (capable of analysing over 20 different parameters) with Colour Discs and Reagents for 250 Tests of Chlorine (Free, Total & Combined). Other tests are available upon request.

All the above are housed in a rigid and fully lockable robust Carrying Case and supplied complete with full operating instructions and Water Quality Report Sheets and a small Carry Sack for handling consumables in the field
