Laboratories using a deioniser system to generate deionised water in house should test the water produced regularly, to ensure the system is working well and producing required water purity.
In standard water the conductivity result will change by around 2 per °C change. In deionised water the effectof temperature is amplified, and can reach as high as 10percentage per °C change.
Only some meters can easily read the low conductivity levels found in DI water. Meters or electrodes which are not specifically designed for DI water will be very slow to give results and may drift -not be able to settle on one value for an accurate reading. The Myron 6PFC Ultrameter is able to read ultrapure and DI water easily and has built in automatic temperature compensation for accurate results.
While making it ideal for field work or work around a site, The simple to use, handheld unit is also very robust.
This meter also has being added benefit able to measure pH, TDS, ORP and free chlorine. The InLab 742 ISM probe by Mettler Toledo is specifically designed for high purity water, and has built in temperature compensation by an integrated temperature sensor.
This is compatible with a Mettler range Toledo meters, including portable Seven2Go series conductivity meters. This is compatible with a Mettler range Toledo meters, including portable Seven2Go series conductivity meters.
