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.

The PermaNet system from Halma Water Management (UK) transmits leak data collected from Permalog+ loggers directly to an office computer wirelessly via network radio or SMS repeater. The effectiveness of Permalog®
technology
has been proven all around the world – from Las Vegas to Beijing – and in some of the harshest conditions on earth. Easily installed on pipe fittings, the loggers listen for the noise made by water leaking from pipes and, when a potential leak is detected, they enter an alarm state and transmit a radio signal to indicate a "LEAK" condition.
Loggers can be quickly deployed and used repeatedly with no disruption to the surrounding area or to the water supply, and the precise location of each logger can be recorded onto detailed GPS mapping software as it is put into the ground. Each is immersion-tested to IP68, enabling continuous operation even in flooded chambers. They are powered by low cost, replaceable batteries and are tough enough to ensure that long-term low leakage levels can be achieved and held easily, with minimum maintenance.
PermaNet can be configured to send an automatic alert whenever one of the loggers reports a potential leak, meaning leakage teams' speed of response and accuracy of deployment can be maximised. This increased efficiency means that both new and existing leaks can be targeted more quickly; saving more water, and reducing the risk to surrounding infrastructure.
A complete network of devices creates a powerful system to supply up- to-date flow data and effective water management. Leak sizes can be determined by matching daily leak alarms with flow data, and problem zones can be brought quickly and effectively under control.
A new development called ALMOS (Acoustic Leak Monitoring Online System) now uses this data, in con - junction with popular online mapping technology, to provide a live, on-screen tracking application for deployed Permalog loggers from any internet- connected PC, without any specialist software. The location and leak status of each logger is displayed directly and accurately on a map of the area, with further information available at the click of a button.

Measure: Conductivity Resistivity TDS pH
ORP mV or ppm Free Chlorine
Temperature and more...
Ultrameter II With all new features and functions …
The Ultrameter II still delivers the most accurate dissolved solids measurements of any instrumentation and the greatest degree of accuracy available for pH, ORP and Temperature measurements, but has been redesigned to include an LSI/Hardness Calculator, Free Chlorine Measurements and Bluetooth®
data transfer with the optional bluDock™ accessory.
The LSI calculator makes it easy to analyse the scaling nature of water in the lab or in the field. The calculator computes the saturation index of a sample based on measured and inferred values for pH, temperature, hardness and alkalinity. You can then change any of these values in user adjust mode to analyse the effect of the change on water balance. User mode also allows you to input measured values for alkalinity and hardness as determined by other independent testing for a precise saturation index value.
Within the LSI Calculator is a Hardness calculator that allows you to select either ppm or grains of hardness units.
Free chlorine measurements are mathematically derived from Oxidation Reduction Potential measurements. The mV to ppm free chlorine conversion algorithm is based on a published conversion curve and bench testing performed at the Myron L Company. With this new feature Myron L instruments can measure a dynamic range of sanitiser concentrations that is wider than the range of a colorimetric test kit.
With the bluDock™ accessory package, the Ultrameter II can now also transfer data wirelessly using Bluetooth® technology.
The Ultrameter II also features KCl, NaCl, 442™ and User-defined solution modes for proper solution modelling in diverse applications. Autoranging allows instrument to maintain resolution for solutions with widely varying concentrations. The pH/ORP sensor is user replaceable and can be calibrated to 1, 2 or 3 points depending on requirements. 4-wire conductivity cell construction, extremely stable circuitry and proprietary conversion algorithms deliver reliable repeatable results.
Ultrameter II is compact, portable, waterproof and buoyant, easy to calibrate and easy to use. Call the Myron L Company today to see why customers are saying this is the instrument they've been waiting for.
