Oxygen and pH value / Water<br />
Oil-Test Paper and<br />
pH Test Paper<br />
To test for oil in water or in soil<br />
and to find hydrocarbons, especially<br />
in fuel (Diesel) and motor oil.<br />
Even if the water is self-coloured,<br />
a deep blue colouring of the test<br />
tape indicates even a small oil content.<br />

Watertest Laboratory<br />
A really compact box – laboratory for a fast analysis of waters (e.g. drinking,<br />
water, surface water, water of aquaria). All the applied chemicals are<br />
neutral in reaction to the environment, which means, none of the test<br />
solu tions endanger water. The used test solutions can be disposed of<br />
via the home waste water system. Sufficient for 50 to 60 tests:<br />
• Ammonium 0.05 – 10 mg/l<br />
• Nitrate 10 – 80 mg/l<br />
• Nitrite 0.02 – 1.0 mg/l<br />
• Phosphate 0.5 – 6.0 mg/l<br />
• ph-Value 5.0 – 9.0<br />
• 1 Drop = 1° German hardness (dh).<br />
