Water Sterilisation Testing Kit

Sterilising a large amount of water is fairly straightforward- tip the right amount of chemicals in and the job is done…or is it? It is very hard to know if you have added the right amount of steriliser to water in order to kill off all potential bugs so a kit is needed to test the sterilised water to confirm it is actually safe to drink and the British army introduced a little kit in the Second World War to do just that. This continued to be manufactured and used right through until at least the 1960s and today we are taking a look at a 1962 dated example. This little kit comes in a green painted wooden box with a webbing handle attached to allow it to be easily carried:

There is no mistaking the contents of this box as they are painted nice and clearly on the lid:

The date, a War Department arrow and the letters WD are painted on the front:

Opening the kit up reveals the contents:

The underside of the lid gives the user instructions on how to test the treated water:

In order to do this, the box contains two white melamine beaker, each marked with a /|\ mark on the base:

Unbderneath these beakers are the rest of the tools in the kit, each held in place with a little swivelling metal retention tab:

The complete contents of the box are the two beakers, two metal rods to stir, a small measuring spoon and a bottle of testing tablets:

The tablets are held in a small plastic bottle, with a label sellotaped to the outside indicting that it holds 100 natura red water testing tablets:

These were manufactured by T & W Bailey of London:

This little kit is in remarkable condition and I doubt it has ever been used, although I am not about to count the tablets to ensure there are still 100 of them!
