•	Sufficient reagents and strips are provided to perform 100 tests.

•	The manufacturer offers the same kit with instructions in both English and Bangla languages (ref. no. 28178-00)

•	A replacement kit for reagents only is available (manufacturer ref. no. 28232-00).

5) 0005522 - Visual Arsenic Detection Kit, 200 This kit is manufactured by Wagtech International Ltd. Berkshire, UK. •	Manufacturer reference Wag-WT0950, Visual Arsenic Detection Pack-200

•	The kit features a reaction vessel with a unique tri-filter cap, which removes excess arsine gas as well as any hydrogen sulphide which may also be given off as a by-product of the reaction.

•	Measuring range (color scale graduation): <10, 20-40, 50, 60-80, 100, 100-200, 200-300, 300-400, 400-500µg / liter (ppb).

•	The results can be compared visually with the color scale or the filter holder inserted in the photometer of the digital Arsenator (UNICEF item no. 0005523) to get a digital readout of the results.

•	The kit contains the following: two reagents (one in tablet form and the other in pre-measured individually packed sachets), a reaction vessel, a dilution graduated tube, four filter holders for the collection and detection of arsenic, four filter holders (scrubber) for the elimination and removal of any arsine gas, four hydrogen sulphide filters, a color comparison chart, and waste disposal bags.

•	Sufficient tablets, powder sachets and filters are provided to perform 200 tests.

6) 0005523 - Digital Arsenator – (mentioned earlier) This kit is manufactured by Wagtech International Ltd. Berkshire, UK. •	Manufacturer reference: Wag-WT0900, Wagtech Digital Arsenator. •	The Digital Arsenator is a fully portable arsenic detection system featuring a portable battery-operated digital photometer capable of giving accurate digital readings of the discoloration of the filters as a result of the reaction of the two reagents with the arsenic in water. It gives a direct readout in (ppb) of arsenic in water specifically within the critical range of 2 µg/ liter (ppb) to 100 µg/ liter (ppb). The photometer includes a timing device to monitor the length of the chemical reaction.
