“We are looking to order an additional PH Probe (Model 648) just the same as the ones we have purchased before.   We are trying to use it with a Oakton PH150 and I think you guys were able to wire it up to work with those when we first purchased. We have a floating probe that we use to check PH levels at a different time and we want to get away from the non-durable probes we have been using. “

“Sensors are working well, we added in a few more in our process and I wanted to have a couple spares on hand.”

“All our pH/ORP sensors are working very well – we will be starting up a new process in the next month or so and will likely need a few more sensors.”

“Performed perfectly.” 

In a high scaling environment where the probe is submerged. Used with a GLI 53 pH controller in the USA.

“Equipment is working great. We set up a 648 probe on our brine feed line coming into the plant and have had no issues so far.”

“The probe is working very well so far, no issues there. We currently have the probe in a “stripping” tank, it is filled with slurry and HCL. The slurry is thick and is stirred with a large mixer inserted in the top of the tank. If the slurry is not mixed sufficiently, it will harden, this makes it very difficult to pump out of the tank. The pH in this tank is very critical to our process, we must keep it at a 2 (1.95-2.05 band). The temperature in this tank is about 45°C. We currently have the probe threaded into a piece of pvc pipe and stuck down into the top of the tank (away from the mixer blades).”

The ”3 test probes installed currently all reading amazing!!!!”

from an Electrical and Instrumentation Supervisor at a major mining company in Canada using the IC Controls Model 607 pH sensor and Model 648 pH Sensor to resolve ground loop problems and extend sensor life in their hydrometallurgical beneficiation process.
