Drinking Water Probe for Cold Low Conductivity Waters
With the many variations seen in the quality of drinking water in different regions, there are occasions when a standard pH electrode proves to be unsuitable for measuring the pH quality of the water. Sentek (UK) have done a great deal of research with different types of glass, and also reference systems, which has enabled them to come up with an electrode which does meet this criteria. The P11 Drinking Water Probe is ideal for particularly cold low conductivity water of low ionic strength.
Reader Reply Card no 89 A Revolution in On-Line Liquid Analysis
BioTector Analytical Systems Ltd. (Ireland) manufactures an innovative range of on-line liquid analysers, which apply a totally new approach to eliminating the many problems associated with on-line TOC, TN and TP measurement.
The BioTector is designed to analyse everything – from clean water to the most corrosive & polluted samples, with no filtering requirements. It’s patented oxidation method is what makes the BioTector unique. This oxidation process, known as Two Stage Advanced Oxidation (TSAO) is extremely aggressive and is therefore totally self-cleaning (Hydroxyl Radicals at an oxidation potential of 2.8 is only below fluorine). The reaction is unaffected by Chlorides (salts) up to 30% and the system can handle oils, fats and calcium up to 12.5%. Hence the BioTector is deemed to be the most reliable on-line liquid analyser on the market, with 6 month service intervals and <99.7% uptime with an accuracy of +/- 3%. It is designed so that there is no drift and therefore calibration is not required for the correct operation of the system.
The BioTector makes direct measurements without dilution in 6.5 minutes (TOC) and on a wide variety of ranges from 0-5mg c/l all the way up to 100,000mg c/l. Up to 86,000 samples per year can be successfully measured by the
BioTector and the analysers can be calibrated to read TOC, TN, NO3, TKN, TP, COD, BOD, TC, TIC and VOC. There are now over 500 BioTector units installed worldwide, many of which are operating in applications that would have been impossible with conventional technologies.

New Hand-Held Photometer for Chlorine Analysis with Powder and Tablet Reagents
SEAGUARD® String System
The Tintometer Ltd (UK) has introduced a compact, easy-to-use, portable photometer to enable the measurement of Chlorine from 0.01 – 6.0 mg/l. The compact, ergonomic, waterproof (IP 68) design is ideal for the measurement of waste and drinking water and beverages both in the laboratory and in the field.
Uniquely, the MD100 from Lovibond® can be used to measure
Chlorine using both powder and/or tablet reagents with specific calibration for both reagent types. Users no longer need to make the choice at time of instrument selection, avoiding limitation in options further along the line or, inadvisably, using tablet reagents in a powder specific instrument or vice versa.
The MD 100 includes a One Time Zero (OTZ) function enabling one time calibration for multi-tests and multi-occasions, saving valuable time when taking measurements with the backlit display clearly presenting the accurate, reproducible results every time.
