Which form of chlorine do you want to measure?
Free chlorine is a measure of how much chlorine is free and available to sanitise. That is, how much chlorine has not yet reacted with contaminants in the water and is therefore available to kill harmful bacteria and algae. Free chlorine occurs in two forms: hypochlorous acid and hypochlorite ion.
Combined chlorine is a measure of chloramines. Chloramines are the by-products of hypochlorous acid’s reactions with contaminants. Once hypochlorous acid has ‘combined’ with harmful substances in the water (such as sweat in the case of swimming pool water), chloramines are formed. Think of them as waste products that need to be removed from the water. There is no way to directly test for combined chlorine, instead we need to test for total chlorine.
Total chlorine is simply a measure of both free chlorine and combined chlorine. To work out combined chlorine, subtract your free chlorine reading from your total chlorine reading.
total chlorine – free chlorine = combined chlorine

PEHANON is a special pH indicator test strip which has the following benefits:
Any sample colour has the same effect on both the reference colours and the reactive pad. This ensures unadulterated readings in coloured solutions. The user can be sure to get accurate pH values.
An invisible hydrophobic barrier just above the top colour field prevents capillary action of the test solution beyond this point. The handle will remain dry and clean, whatever the sample is. This makes using the strip very safe.
pH values can be determined without a separate colour chart. Workers can use single strips instead of complete packs with colour chart, which makes PEHANON economic.
14 different measuring ranges available. Find the ideal strip for your application!

Arsenic in solutions has to be converted into arsine with zinc and hydrochloric acid and purged from the solution. Arsenic test paper must not be dipped into the solution, it works only in the gas phase.
Store Arsenic Test Paper in a cool, dry place. Avoid exposure to sunlight and moisture.
For the quick and easy determination of the relative atmospheric humidity.
Moisture sensitive goods, such as electronics and optical systems, have to be stored at low atmospheric humidity. They are usually packed in sealed plastic bags together with a desiccant. Moisture Indicator Paper is used to determine if the desiccant is active and if moisture is effectively kept away from the goods.
Moisture Indicator Paper is simply exposed to the atmosphere in question. When the color of the pad does not change anymore, the humidity can be read off.

For the quick and easy determination of water hardness.
Water hardness is determined by the amount of calcium and magnesium ions present in the water. Water hardness plays an important role in a wide variety of industries and applications.
Hard water can cause calcification and soft water can be corrosive, and so monitoring water hardness is very important for the protection of machinery, appliances, pipes, heating units and swimming pools, for example. Hard water inhibits the lathering of soap, so more detergent has to be used in hard water to achieve the same cleaning results as in soft water. Hard water can also adversely affect the taste and appearance of food. Some examples of industries where water hardness must be monitored include the food processing industry, laundry and sanitation, aquaculture, drinking water, textile and water treatment industries.
Water is often simply classified as “soft” or “hard”. The following values generally apply to these terms:
>50 ppm CaCO3 = very soft water
50 – 120 ppm CaCO3 = soft water
120–240 ppm CaCO3 = medium hard water
240–360 ppm CaCO3 = hard water
< 360 ppm CaCO3 = very hard water
AQUADUR water hardness test strips are available in a wide variety of different gradations and packaging options.
AQUADUR water hardness test strips are the ideal choice to quickly, easily and reliably determine water hardness.

For the fast and reliable determination of EDTA (Ethylendiaminetetraacetate), NTA (Nitrilotriacetic acid) and other complexing agents in solutions. The easy dip & read procedure provides a reliable result within 15 seconds.
Complexing agents such as EDTA or NTA are frequently used as additives in washing and cleaning agents, cosmetics, the photo and paper industries. Since such additives are poorly biodegradable, the dosage used must be carefully measured. QUANTOFIX EDTA test strips are ideal for checking the concentration. The absence of such complexing agents can also be established with these test strips.
In proteomics labs EDTA is also used to regenerate Ni- and Co-precharged chromatography columns (HPLC columns) which are used to purify recombinant proteins. Prior to the successive analysis, QUANTOFIX EDTA is used to control if EDTA has completely rinsed out. This may dramatically reduce the rinse time and therefore increase the throughput and the capacity.
The following complexing agents can also be tested with this method:
– Nitrilotriacetic acid (NTA, commercial name: Titriplex® I)
– 1,2-Cyclohexylenedinitrilotetraacetic acid (commercial name: Titriplex® IV)
– Diethylenetriaminepentaacetic acid (commercial name: Titriplex® V)
– Bis(aminoethyl)-glycolether-N,N,N‘,N‘-tetraacetic acid (commercial name: Titriplex® VI)
Conversion factor: 1 mg/L EDTA = 0.7 mg/L NTA
Directions for use
Dip the test strip into the sample for 1 second. Shake off excess liquid. Wait 15 seconds. Compare test field with the colour scale. If EDTA is present, the test field turns orange to yellow depending on the concentration. Should EDTA not be present, the test field turns red.

For the quick and easy determination of nitrite and pH in cooling lubricants. The easy dip & read procedure provides a reliable result within 1 minute.
QUANTOFIX Nitrite/pH is ideal for monitoring two important parameters in cooling lubricants. The nitrite test is an indicator for bacterial growth in the cooling lubricant cycle. It allows early counteractive measures and therefore increases the lifetime of the cooling lubricant. An added benefit is significant cost savings. A weekly determination of the nitrite concentration is also recommended to protect workers from carcinogenic nitrosamine. High levels of nitrite in the cooling lubricant foster the formation of this carcinogenic compound.
The pH test is specially optimized for the demands of cooling lubricant analysis. Short testing cycles allow an early detection of pH changes. Counteractive measures can be performed to keep the pH at the optimal level. This ensures optimal protection against corrosion, inhibits bacterial growth and therefore reduces maintenance costs.
Directions for use
Take a sample (do not hold the test strip in flowing cooling lubricant). Dip QUANTOFIX Nitrite/pH test strip with all test fields into the sample for 1 second. Shake off excess liquid. Wait 60 seconds. Compare test fields with the colour scale.
