Senz Redox tester

This easy to use and lightweight Redox potential value tester is ideal for oxidation-reduction potential (ORP) measurements.

The instrument is suitable for a wide variety of applications, e.g. monitoring water, pollution, chromatic wastes, oxidation of cyanide, bleaching of pulp etc.

The Redox tester is housed in a robust, water resistant case and measures mV over the range of 999 to -999 mV with a 1 mV resolution and an accuracy of ±40 mV.

Dissolved Oxygen Electrode(s) Maintenance

ETI instruments include the WalkLAB Dissolved Oxygen meter and the Senz Redox (ORP) tester.

Always rinse the electrode in distilled water between each test.

The membrane must be kept wet at all times. When not in use the probe should be stored with the tip in a beaker of deionised water or for longer periods (overnight) in the protective sheath supplied, with a sponge in the bottom of the cap soaked in deionised water.

Before use, or after replacing a membrane (WalkLAB), ensure that the probe has been given sufficient time to polarise. Refer to the Instruction Manual for details.

Membrane replacement and electrolyte replenishment/replacement is recommended if readings become sluggish or the electrode does not respond.

Cleaning: In normal use it should only be necessary to rinse the probe in deionised water between each determination, however when using the electrode in liquors, sludge, or polymers, etc., a coating may be deposited on the membrane causing slow response or drifting. This can be reduced by rinsing in deionised water. In such samples more frequent membrane replacement may be required.

When replacing membranes ensure that no air bubbles are trapped in the KCl (electrolyte) fill solution, and check visually to see that the membrane is not damaged or creased when screwed on.
