What are some Industrial Challenges?

Process applications present some major challenges to the pH measurement system. The most common are long distances between the sample and the meter, high and low temperature extremes, electrical interferences, high pressure, poisoning or fouling of the junction/reference electrode and chemical or physical breakage. For each of these factors, Hanna Instruments has developed specific solutions in the form of electrode features to address these issues. The result is excellent performance for these types of process applications.

What is Ground Loop Matching Pin Technology?

Fluctuation of readings and short electrode life can be related to a ground loop problem. This is very common in industrial measurement systems. The solution is an electrode with a ground loop matching pin which is standard in all of the HI 1000 series. Many transmitters and controllers include a differential input which effectively eliminates this problem. Hanna's 500, 600 and 21/22 series controllers all have this feature. The life of the electrodes will be greatly extended and the labor and time to change out electrodes will be minimized. Bottom line: these pH probes will save the user time and money.

"HANNA pH meters have stood by me through thick and thin, the most reliable, easy, and accurate way to gain ph data. and don't even get me started on the tech support, I wish everybody was as nice, knowledable and friendly as your people are thanks again for your dedication and accuracy in scientific instruments."
