Description
Zinc occurs in small amounts in almost all igneous rocks. Zinc imparts an undesirable astringent taste to water. Tests indicate that 5% of a population could distinguish between zinc-free water and water containing zinc at a level of 4mg/litre (as zinc sulfate)*. Water containing zinc at concentrations above the range 3–5 mg/litre also tends to appear opalescent and develops a greasy film when boiled and has an undesirable astringent taste.
In natural surface waters, the concentration of zinc is usually below 10 μg/litre, and in ground waters, 10–40 μg/litre*. In tapwater, the zinc concentration can be much higher as a result of the leaching of zinc from piping and fittings*. Drinking-water usually makes a negligible contribution to zinc intake unless high concentrations of zinc occur as a result of corrosion of pipings and fittings. Under certain circumstances, tapwater can provide up to 10% of the daily intake*.

Benefits of testing for Zinc:
- A certain amount of zinc is required, but an excessive amount can lead to zinc poisoning.
- Symptoms can include fever, nausea, vomiting, stomach cramps and diarrhoea, sometimes accompanied by bleeding and abdominal cramps.
- Increased daily dosage above the recommended dietary allowance has also resulted in copper deficiencies and the impairment of various immune responses.
- A daily dietary requirement of zinc of 0.3mg/kg of body weight and a provisional maximum tolerable daily intake (PMTDI) of 1.0 mg/kg of body weight (35) has been proposed. The daily requirement for adult humans is 15–22 mg/day*.
These patented Zinc Check water quality test strips are easy to use and designed to eliminate the need for breakable meters that require calibration:
- Simple Dip-Wait-Read Testing Method.
- Test strips are stored in a plastic container with a detailed colour chart to protect them.
- Ideal for quick and reliable testing of water.
- Accurate results are achieved in under one minute.
- This product is safe and easy to use since there are no chemicals to mix, an MSDS is not required.
- Factory-calibrated water quality test strips.
- Since there is no glass required to run the test, it is ideal for use in controlled areas.
Suitable for: fresh water samples, including water from taps, wells, springs, boreholes, ponds, as well as rain water
Content: 50 strips
Sensitivity: 0, 2, 5, 10, 20, 40, 100 mg/l
Interferences: Similar colour development may occur in the pressence of Cu+2 (>0.1ppm), Mn+2 (>5ppm) and Fe+2 (>10ppm).
Total Test Time: 23 seconds
How to Use:
- Dip one strip into a water sample for 3 seconds.
- Remove the strip and shake once to remove excess water.
- Wait 20 seconds for the colour to develop, and match with the closest colour match to determine your concentration of Zinc. Complete colour matching within 20 seconds.
Please note: Most interferences from other metals can be overcome by adjusting the pH between 4.0 to 5.5 and adding sufficient Sodium Thiosulfate before test analysis. Since Zinc also forms a weak Thiosulfate complex, this test is empirical and demands the use of identical techniques for sample with and without the Thiosulfate. Store in a cool, dry (below 32°C) place and away from excess heat and direct sunlight.
Keep away from children and pets. Avoid contact of test areas on strips with skin & eyes, do not ingest or expose to acids.
