Automatic Temperature Compensation many modern pH controllers also read solution temperature and have auto temperature compensation fitted as standard.

We are able to supply pH electrodes with built in ATC and we are also able to supply separate stainless steel auto temperature compensators.

These can be specially sized and have a special temperature sensor inside to suit the instrument in use. Great care must be taken to ensure the correct specification temperature sensor is used. Many large manufacturers use obscure values of ATC fitted inside their electrodes to try to prevent the use of alternative electrodes.

ATP100-10ST Stainless steel automatic temperature compensator temperature range 0 - 100oC mounting by 1/4” BSP male thread, length 100 mm cable length 3m many other variations can be made please ask us.




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.
