ChekNsee Drinking Water Potability Test Kit (CNC2) is a specialized screening kit designed to detect the coliform group of bacteria in drinking water. Coliform bacteria are found in sewage and the intestines of humans and animals, and their presence generally indicates that harmful disease-causing bacteria may also be present.

This kit allows you to check water from all kinds of sources — taps, purifiers, coolers, storage tanks, rivers, ponds, springs, borewells, and more. The test is extremely simple, requires no laboratory or technical expertise, and can be carried out by anybody, anywhere: homes, offices, factories, shops, banks, hospitals, hotels, schools, hostels, and clinics.

Water contaminated with bacteria is a major cause of water-borne diseases such as diarrhoea, dysentery, typhoid, paratyphoid, gastroenteritis, and cholera. Detecting these dangerous but invisible predators is normally the domain of a microbiologist working in a sterile laboratory. Not anymore. Modern science has made water testing so easy and convenient that anyone can do it at home.

The kit uses a simple colour-change method. Just collect the water sample in the provided bottle, mix it with the pre-loaded media bud, keep it in a warm place for 18–24 hours, and observe the result. If the liquid remains purple, the water is potable. If it turns yellow, bacterial contamination may be present and the water should not be consumed until the source is corrected.

Regular use of ChekNsee ensures safe water quality, helps detect contamination early, supports routine testing, improves safety standards, reduces health risks, and delivers consistent, reliable results.

Frequently Asked Questions - CHEKNSEE Drinking Water Potability Test Kit

Q1. Is ChekNsee easy for normal household users?

Yes. The kit is designed as a simple consumer screening product with straightforward handling and a clear colour-based result format. No technical background is needed.

Q2. Can I use it for water from my water purifier?

Yes. Many users want to test the water they actually drink from a purifier outlet rather than assuming the purifier is always working perfectly. It is especially useful after purifier service or when filters are overdue.

Q3. Does ChekNsee replace a laboratory test?

No. It is a screening test meant for early warning and consumer-level monitoring. If the result turns yellow or if you need official or comprehensive analysis, use an accredited laboratory or contact the appropriate local authority.

Q4. What if the water looks clear but the test turns yellow?

Visual clarity is not enough to judge microbiological hygiene. If the bottle turns yellow, treat the water as unsuitable for drinking until the cause has been investigated and corrected.

Q5. How often should I test my drinking water?

Frequency depends on your water source and risk factors. Many consumers use it after purifier maintenance, tank cleaning, monsoon events, plumbing work, or whenever they have doubts about water safety.

Q6. Can I use it for school, office, or hostel drinking water?

Yes. It can be useful for consumer-oriented drinking water screening in shared spaces such as schools, hostels, offices, clinics, guest facilities, and common water coolers.

Q7. What sources of water can be tested with this kit?

You can test water from taps, RO purifiers, UV purifiers, storage tanks (overhead and underground), borewells, water coolers, dispensers, rivers, ponds, springs, and municipal supply lines.

Q8. What does "no colour change" mean?

If the liquid in the bottle remains purple after 18–24 hours, the water did not show a positive reaction for coliform bacteria under the test conditions and is considered potable. Continue normal hygiene practices and repeat screening periodically.

Q9. What should I do if the water turns yellow?

Do not drink the water. Switch to a safe alternative source immediately. Inspect your purifier, storage tank, pipeline, or local supply conditions. Seek confirmatory laboratory testing if required.

Q10. Is an incubator or any special equipment needed?

No. The kit is designed to work at room temperature or in any warm place. No incubator, autoclave, or other laboratory equipment is required.
