• Graduation: 0-0.5-1-5-10-25 mg/L Nitrate
• 100 strips/pk
• This test measures low levels of nitrite used mainly in environmental analysis, surface water investigations and aquaristics
• This test determines the level of nitrite in boiling water and cooling water
• These strips can also be determine the concentration of nitrite in wine and seafood

• Strips can be held in the specimen until the final colour change is observed, they can be used consistently with minimal risk in weakly buffered solutions
• Colours can be matched accurately with the colour chart as there is no cross-contamination between the pads on the strip.
• No specimen contamination
• Slim packaging provides portability and safety
• Nothing to prepare before use
• Consistent batch to batch measurements against accurately printed colour charts

• Graduation: 0-500-1000-1500-2000 mg/L Peroxide100 strips/pk
• J-QUANT® Peroxide 25 test strips are an excellent choice for testing residual peroxide in production equipment levels after disinfection.
• The test strip will show a value of 0 mg/l if there is no peroxide in the sample therefore the process can move forward.
• The finished product is also tested for peroxide if it is made from a number of parts that have been disinfected with peroxide as a final check

• Graduation: 0-10-25-50-250-500 mg/L Nitrate
• 100 strips/pk
• Regular testing of nitrate levels in food is important e.g. potatoes and in preservatives as high levels can affect the quality and consumer health
• Nitrate is derived from the decomposition of animals and plants
• Nitrate is more frequently measured than ammonium in ponds and aquariums to maintain the quality of water
• J-QUANT® Nitrate 500 ensures a rapid and safe way to check nitrate levels

Before fermentation, Johnson Test Papers’ Wine pH test strips are used to test the pH of the juice. They can also be used to test the pH of kombucha tea and cider. These strips work within the pH range 2.8 - 4.4. The optimum pH of yeast is between 5.2 - 5.5, which falls within the measuring capacity of the narrow-range Beer pH test strip (pH 4.6 - 6.2), to test for beer mash.

J-QUANT® Chlorine

Chlorine in solution such as chlorinated disinfectants or sanitisers can be measured easily and rapidly with this basic, reliable and cost effective test.

There are no reagents to mix as everything is on the test strip for the reaction to occur.

Depending on the level being determined, a solid result can be seen in less than one minute.

• Graduation: 0-2-5-10-20-40-80 mg/L Nitrate
• 100 strips/pk
• Colour changing
• Nitrite can provide an indication of contamination in the environment.
• Aquarium, industry, wastewater and drinking water analysis is, therefore, an appropriate list of examples where nitrite measurement is possible.
• Nitrite build up in aquacultures and fish farming through the breakdown of organic matter can impair the filtration units ultimately causing harm to the fish.
• It is very important therefore to test for nitrites in this environment.

J-QUANT® Fluoride J-QUANT® Fluoride 100 Test Strips are used for determining the amount of fluoride in tap water supplied by local water supply companies. They assist by providing a semi-quantitative value either below or above predetermined guidelines and allow for quick assessment of the amount of fluoride. Carrying out the test by including sodium dithionite in the sample will prevent the white discolouration generated by chlorates and bromates without influencing the result.

• Graduation: 0-100-150-200-250-300-400-500 mg/L
• PAA 100 strips/pk
• Used in healthcare, pharmaceuticals, cosmetics, agriculture and the food and beverage industry.
• In these industries the disinfectants are usually in concentrate form that need diluting before use.
• Due to its measuring range this test is suited to testing for the effective levels of peracetic acid in such disinfectants.
• Peracetic acid is unstable therefore frequent testing is required.

• Graduation: 0-500-1000-1500-2000 mg/L PAA
• 100 strips/pk
• Peracetic acid based disinfectants usually come in concentrate form to save on shipping charges and require diluting before use.
• Depending on the industry and the disinfecting purpose different concentration levels are required. Due to its measuring range this test is suited to testing for the effective levels of peracetic acid in such disinfectants.
• Therefore these strips provide assurance that disinfection has taken place correctly by providing a semi-quantitative result Peracetic acid is unstable therefore frequent testing is required.

• Graduation: 0-5-10-20-30-50 mg/L
• PAA 100 strips/pk
• In the drinks industry, bottles and packages and disinfected using peracetic acid, which are then washed out to remove the residual disinfectant.
• These simple products can rapidly test for peracetic acid residue after rinsing to check that it has been removed.

• Graduation: 0-1-3-10-30-100 mg/L Peroxide
• 100 strips/pk
• Useful for many applications, e.g. In chemical laboratories, organic solvents containing peroxide can be checked as they could explode upon heating.
• Soak the test pad in the solvent sample then allow to dry
• Add a drop of distilled/demineralised water and if the pad remains white then there is no peroxide present.
• Testing for residual peroxide where high strength disinfectants are utilised for cleaning such as the dairy industry, drinking water, pools and hot tubs
