Milwaukee pH Controller replacement probes

[mutley29]

Hi All

 

I'm not sure whether its early on a Sunday or just me but i don't seem to be able to find replacement probes for this Controller:

Premium Aquatics

 

The controller probe in my sump at the moment is telling me my pH is dropping to 7.6 even after calibrating , but salifert tests are telling me it's all good at 8.2

 

So i was wondering if the probe was on it's last legs and needed replacing

 

Anyone know where to purchase said probes

 

Any help appreciated

Did you replace the battery?

It's on a Power supply 12 VDC adapter

Hmm well, another thing you could try is perhaps to soak the probe in vinegar to clear off any build up...
