Description Videos Show Reviews Taylor Test Kit sureCHECK Safety Plus, Alkalinity/Bromine & Chlorine (hi range), DPD/pH (Trouble -Shooter) Taylors sureCHECK test kits are designed for spa and pool owners who have low bather loads and test theirwater between visits from a service technician or tripsto their pool supplies store. This series uses the samequality reagents as Taylors kits for professional analysts.Buyers have a choice of three progressively more sophisticatedmodels: Safety Test, Safety Plus, and Total Balance, asdescribed below.Every sureCHECK kit is available in our classic casethesolid blue, injection-molded plastic kit which is so durable itcan be refilled season after season. Tabs on every case makethem easy to hang from hooks.

Chlorine Other halogens and oxidized manganese may cause positive interference. pH Iron > 10 ppm may cause negative interference. pH Sanitizer levels > approx. 10 ppm may cause a blue-purple color resulting in false high readings. Wait for sanitizer level to decrease to normal levels and retest to assure an accurate reading. Total Alkalinity High halogen level may change indicator reaction from green/red to blue/yellow; to prevent, add thiosulfate prior to testing. REAGENT SHELF LIFE All reagents have a shelf life, whether they are liquids, powders, crystals, tablets, or test-strip pads. If kept dry, powders and crystals are very stable; acids are also long lived. Date of manufacture is not the controlling factor when it comes to shelf lifestorage conditions are more important. As with all perishables, reagents are sensitive to environmental influences and will last longer under controlled conditions . To this end, we recommend: Storing reagents at a consistent temperature in the range if3685F (229C); extreme temperature fluctuation, say from a refrigerator to a hot car trunk, causes reagents to deteriorate. Keeping them out of prolonged direct sunlight. (Note: their brown plastic bottles help protect very light-sensitive reagents.) Segregating reagents from containers of treatment chemicals. Replacingcaps immediately and tightening them carefully so that exposure to air and humidity is limited. Avoidingswitching bottle caps, placing bottle caps on soiled surfaces, repouring reagents into contaminated containers, or touching test strip pads. Taylor formulates its reagents to remain effective for at least one year, with only very few exceptions (molybdenum indicator in liquid form is one; after four months old it should be tested against a standard periodically). As a general precaution, replace all reagents more than one year old, or at the beginning of a new testing season .
