Palintest Total Alkalinity Test Tablets in a 250 tablet bottle - Total Alkalinity in a range of 0 - 500mg/l 
  What is Total Alkalinity? This is a measure of all the alkaline materials in the pool water. In the pH range found in pool waters, the alkalinity is likely to be present in the form of Sodium Bicarbonate. At the correct level, the pH will not alter rapidly as the water is said to be buffered. If the total alkalinity is below 80 p.p.m. then the water will be insufficiently buffered and if it is above 200 p.p.m it will be excessively buffered. In either case the effect of the addition of chemicals will be difficult to control. 
 Total Alkalinity - 250 Tablets - Add one tablet to sample in a stoppered container. Shake to disintegrate tablet. Repeat until yellow colour changes to bright red. 
 Total Alkalinity can then be calculated as: 50ml sample container = number of tablets added multiplied by 40 then minus 20 to give you your Total Alkalinity reading. i.e. 6 tablets added, so (6 x 40) - 20 = 220 mg/l 100ml sample container = number of tablets added multiplied by 20 then minus 10 to give you your Total Alkalinity reading. i.e. 11 tablets added, so (11 x 20) - 10 = 210 mg/l As you can see from the above examples it is more tablet efficient to use a 50ml stoppered sample of water for testing.

 DPD3 - To Test Combined levels AP033/1 DPD3-XT (HR) Tablets x 250 - High Range 0-10ppm Combined Levels - Only to be used with High Range Photometers. 
 This Palintest Chlorine/10 test uses the DPD method developed by Dr A T Palin and now internationally recognised as the standard method of testing for chlorine and other disinfectant residuals. In the Palintest DPD method, the reagents are provided in tablet form for maximum convenience and simplicity of use. Free chlorine reacts with diethyl-p-phenylene diamine (DPD) in buffered solution to produce a pink coloration. The intensity of the colour is proportional to the free chlorine concentration. Subsequent addition of excess potassium iodide induces a further reaction with any combined chlorine present. The colour intensity is now proportional to the total chlorine concentration; the increase in intensity represents the combined chlorine concentration. In this way, it is possible to differentiate between free and combined chlorine present in the sample. The colour intensities are measured using a Palintest Photometer. The DPD Oxystop tablet is added after measurement for free chlorine but before the DPD XT tablet. It prevents the reaction between shock treatment chemicals and potassium iodide which would give a positive response.
