Alkalinity
Quantitatively, alkalinity is the capacity of the water to react with acid to a specific pH end point. Alkalinity is an important test parameter in a number of industrial water uses, notably in boiler water treatment. Boilers and steam raising plants are normally operated under conditions of high alkalinity to minimise corrosion. Monitoring of alkalinity is an important control test.
Natural and treated waters may contain a variety of dissolved alkaline substances such as carbonates, bicarbonates, hydroxides, and, to a lesser extent, borates, phosphates and silicates. In waters of neutral pH, the alkalinity derives from the presence of bicarbonates.
Total Alkalinity is an important test in determining the aggressiveness or scale tendency of the water. If the total alkalinity is low the water may be aggressive and cause corrosion to pipework and structures. If the total alkalinity is high, the water may more readily promote scale formation. Alkalinity control is therefore an important part of many water treatment programmes.
The following products are available to test for Alkalinity:
Comparator Kits
Comparator tests use visual standards to assess the colour produced when reagents are added to a sample of water. Tablet reagents are used with these kits for maximum simplicity and convenience.
CoolPoolTester
Gone are the days of comparing colours on a chart - with the Coolpooltester, all readings are shown on the digital display! A low-cost photometer designed for home pool and spa owners.
Photometer 7100
The Photometer 7100 is fully integrated with the Palintest system of water analysis. It offers a great value instrumental analysis for an extensive range of water tests.
Photometer 7500
The Palintest Photometer 7500 takes portable water testing to new heights. The smooth good looks cover a solidly engineered instrument with a high specification and high performance.
Photometer 8000
The Palintest Photometer 8000 sets a new standard for water quality testing and ease of operation. It is designed to provide accurate and fast analysis for even the busiest test labs.
Pooltest 25 Professional Plus
The Pooltest 25 Professional Plus features simple selection of over 25 pre-programmed tests. The instrument can store up to 500 test results in its on-board memory and can be interfaced with spreadsheets or pool management software applications.
Pooltest 6
The Pooltest 6 is a quick, accurate and reliable instrument to test for Alkalinity, Bromine, Chlorine, pH, Calcium Hardness and Cyanuric Acid.
Pooltest 9
The Pooltest 9 Professional Pool Photometer builds on the phenomenal success of its predecessor the Pooltest 9, with the same ease of use that made its predecessor the best selling pool photometer in the world. Now with extended chlorine measuring range.
Visual Comparators
Comparator discs have for many years been the standard method of testing commercial and public pools. Aquatic Life Ltd. offers a full range of kits based on the Palintest Comparator and Disc system for the pool operator.
