Redox

Portable Redox Meters

Portable Redox Meters Portable Redox meters are those instruments which can be taken out on to the plant or into the field and used to accurately measure the Redox of a wide range of solutions from process ;vessels to swimming pool water, lakes or rivers. Automated water & Effluent Ltd (AWE Direct) currently offer two styles of portable Redox instrument the increasingly popular stick type and the traditional hand held type with a separate electrode attached to the instrument with a cable.

Redox Transmitters

transmit

The Redox Transmitter is instruments for mounting close say within 3 metres (10’) of the Redox electrode system. The best Redox transmitters have a display and calibration controls for zero and span so the system maybe calibrated or buffered local to the electrode.Effluent Ltd. The current output is an industry standard 4 – 20 mA output with the same two wire which power the 24 VDC transmitter carrying the current output.

Redox Controllers

controllers

Redox Controllers are Redox instruments which has the ability to operate a remote device the output can either by a relay which switches at a preset Redox value or an analog control signal. The analog control signal must not be confused with a recorder output, which is a linear output corresponding to the measuring range of the instrument and should not be used for control.

Redox Electrodes

electrode

A good quality electrode is the secret to any Redox measurement application Automated water & Effluent Ltd (AWE Direct) carry a wide range of electrodes for many applications in water and waste water treatment. Our range includes dip electrodes for immersion into open tanks pits and sumps, insertion electrodes where the electrode becomes part of the pipework and inline electrodes where the solution flows through an electrode holder.

Redox Simulator

calibrate

The APS2 Redox & mV simulator is a source of precise mV signals for calibrating Redox and mV meters. It is substituted for the service electrode and maybe also be used to check the serviceability of extension cables and of wiring within the meters themselves.

Redox Buffers

buffers

Redox Buffers calibrating a Redox electrode and instrument is often referred to as buffering the system. The electrode is removed cleaned and immersed in a solution of a know Redox value and the instrument is set to read this value. This is usually carried out for 2 values so the zero and span can be accurately set. Automated water & Effluent Ltd (AWE Direct) offer buffers in values of 4.00, 7.00, 9.00 and 10.00 Redox either as liquid or powder to mix your own buffer solution.

AWE Direct News:- New Teflon Junction pH Electrodes and Redox Electrodes

We are now able to supply our P8000-10B series high performance combination pH electrodes with a porous teflon liquid junction, and our R8000-10B series of high performance combination redox electrodes with a porous liquid junction.

The new range of P8000 pH Electrodes and R8000 Redox Electrodes are ideal for solutions which are incompatible with ceramic. Some chemical blends involving strong acids or strong alkali solutions can slowly dissolve the ceramic junction. Other substances can block the ceramic junction such as biological effluents which contain fats, oils or greases. 

The P8000-10B porous teflon liquid junction pH electrodes and R8000-10B high performance liquid teflon junction redox electrodes aim to eliminate these concerns.

Portable pH Tester

Portable pH testers and portable pH meters are usually separated into two different types.

Stick Type pH Tester

The stick type pH tester with a replaceable reference. These easy to use pH testers allow the user to insert the instrument into a sample of a solution, directly into a process such as a tank, sump, lake or reservoir. The units have simple push button calibration with buffer recognition and auto temperature compensation. They are often simple to use and the electrode reference can easily be replaced.

Portable pH Meter

A portable pH meter differs from a stick type pH Tester in a number of ways. Usually a portable pH Meter will allow the user to connect an external pH electrode to the device. This allows the user to test not only the pH value of the electrode but also the electrodes response time. This is particularly useful in testing with a pH electrode is nearing the end of it's life span or to diagnose incorrect buffering or connections of a pH electrode or pH controller. In addition pH meters can normally offer an additional benefits not included on Stick type pH Testers. This includes measurement of other disciplines including Conductivity Measurement, Redox Measurement and Temperature Measurement as well as temperature compensation.
