LETZTEST Tube
An easy-to-use presence/absence test for detecting fecal bacteria in water samples. This ready-to-use test is ideal for routine monitoring of drinking water systems in remote locations. The presence of fecal bacteria in water is a clear indication of contamination from human or animal excrement, which carries a high risk of pathogenic microorganisms causing severe waterborne diseases (e.g. Cholera). Monitoring fecal bacteria is crucial to ensure safe drinking water and safeguard public health. According to the World Health Organization (WHO) drinking water guidelines, safe water must not contain any fecal indicator bacteria. (Reference: WHO Guidelines for Drinking-water Quality, Fourth Edition, 2011, page 36)

The presence of fecal bacteria in water is a clear indication of contamination from human or animal excrement, which carries a high risk of pathogenic microorganisms causing severe waterborne diseases (e.g. Cholera). Monitoring fecal bacteria is crucial to ensure safe drinking water and safeguard public health. According to the World Health Organization (WHO) drinking water guidelines, safe water must not contain any fecal indicator bacteria.

LETZTEST Turbidity Tube
Simple, Safe and Independent. A very practical and very easy to use tool for visual measurement of water turbidity which is very often convincing in practice. An essential test prior to water treatment by chlorination (Note: Chlorine is an effective disinfectant where water turbidity is below 5 NTU) and in ongoing water quality monitoring.
LETZTEST pH | Chlorine Tester
The LETZTEST pH | Chlorine Tester is an easy to use tool for measuring free/residual chlorine, total chlorine and pH (acidity) of water samples which is very often convincing in practice. Why measuring chlorine and pH? In many cases testers want to know if a water was disinfected or if the residual chlorine (=free chlorine) level is still sufficient to protect the drinking water from recontamination. The ideal level of free-residual chlorine is said to be 0.2-0.5 mg/L. Disinfection with chlorine is more effective at a pH value below 7.5.
LETZTEST Visual Color Comparator Kit
The LETZTEST Visual Color Comparator Kit is an easy to use and comprehensive tool for measuring Alkalinity | Aluminum | Ammonia | Chloride | Chlorine free and total | Copper | Colour | Fluoride | Iron | Manganese | Nitrate | Nitrite | pH | Phosphate | Total Hardness and many more parameters. Priority parameters defined by the World Health Organisation to monitor easily with this kit: Residual Chlorine: Ensures water is disinfected and safe from disease causing bacteria of fecal origin. Ideal level is 0.2-0.5 mg/L. Chlorination of water systems is more efficient at pH < 7.5 and turbidity < 5 NTU. Fluoride: Watch for teeth mottling at 1.5-4 mg/L, or skeletal fluorosis at > 4 mg/L. WHO limit: 1.5 mg/L. Nitrate: High levels harm infants and pregnant women, causing blue baby syndrome and birth defects. WHO limit: 50 mg/L. Manganese: Affects water taste, odor, and appearance. Can lead to water rejection by consumers. WHO limit: 0.4 mg/L.
