• Graduation: 0-10-25-50-100-250-500 mg/L 100 strips/pk
• Measurement of total sulphite requires further sample preparation
• Sulphite is utilised as an oxygen scavenger in process and boiler water, sulphite levels therefore need to be frequently monitored to prevent over treatment
• Also used for food analysis e.g. fruit juice testing, sulphurated foods (e.g. fresh and dried fruits), shellfish, crustaceans and minced meat products which use sulphur based products to prolong shelf-life
• Used to monitor production and quality of wine
• Compatible with sulphite, bisulphite and metabisulphite ions

• 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.

• 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: 0-100-200-400-600-800-1000 mg/L Peroxide
• 100 strips/pk
• Peroxide 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
• Therefore these strips provide assurance that disinfection has taken place correctly by providing a semi-quantitative result
• Appropriate for measuring inorganic peroxides in aqueous liquids Also suitable for disinfecting and rinsing solutions e.g. food technology, laundries and in swimming pool water

• 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: 0-500-1000-1500-2000 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: 0-0.5-1-5-10-25 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

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.

• 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

J-QUANT® Peracetic These J-QUANT® Peracetic Acid test strips can quickly and reliably measure the level of peracetic acid in liquids. These strips provide consistent results with their easy to use method within 45 seconds of sampling. Peracetic acid is commonly found in disinfectants and is one of the most effective oxiders available. J-QUANT® Peracetic Acid test strips are not influenced by hydrogen peroxide based products if used correctly. Peracetic Acid 50 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. Peracetic Acid 500 This range is used in healthcare, pharmaceuticals, cosmetics, agriculture and the food and beverage industry. 

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.

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.
