Comes in a nice storage box


Contents
Tester, 2 Glass Cuvettes, Instructions, Laminated quick reference card and 6 reagents

Straightforward to use, switch on add 10ml of water to be tested to cuvette and place in checker then press button to zero

Checker then asks for sample with reagent added

Press button which starts a 3 min timer

After which it gives reading

Which in my case is 0.00, and even with the max tolerance would only give 0.04 so well happy with it.
Would be interesting to compare it side by side with the more expensive version
