Pahl\u00e9n test tablets 212971 are reagent tablets for measuring calcium hardness in pool water. They are used together with a Pahl\u00e9n photometer, where the tablets are dissolved in a water sample so the instrument can read the result. Calcium hardness is checked as part of routine water balance control alongside pH and disinfectant levels.<\/p>\n
Item no. 212971 is supplied as a pack of 10 tablets for calcium hardness measurement, marked 1-2. The pack measures 8.5 x 10.5 x 4 cm and weighs 0.065 kg. It is a consumable, so a new pack is needed once the tablets are used up.<\/p>\n
The tablets are listed by Pahl\u00e9n for the Autocheck 3i and Autocheck 15 measuring instruments. They are intended for calcium hardness readings on these units and are not a stand-alone test on their own. The instrument itself is ordered separately.<\/p>\n
Pahl\u00e9n lists measuring glasses for the Autocheck range, item no. 212981 with \u00d8 24 mm for Autocheck I, II and III and item no. 212982 with \u00d8 16 mm for Autocheck II. A tablet crusher and stirring rod is available as item no. 212985. These accessories are supplied separately from the tablet pack.<\/p>","protected":false},"excerpt":{"rendered":"
