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:

  1. Dip one strip into a water sample for 3 seconds.
  2. Remove the strip and shake once to remove excess water.
  3. 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.
