Oh Wow .......

BTW I'm a long time ION Director and KH Director user via a Doser SA and just migrated to a Profilux 4 from an Apex and absolutely loving the sensor stability.

Thanks Gaël

I assume the quote from the troubleshooting guide contains a typo and should read not MORE than every 3 days?

I will try every 2 days with the timer and see what happens.

Is...

What are the pros and cons of using a timer to start an ION Director measurement every 2-3 days?

Less reagent consumption ....

Less accuracy?

Greater sensor wear?

Which type of timer?

Yes but the tube is fully primed

Is it normal that when venting the internal reagent tube the dosing line parts at the connection to the rubber pump head tube?

Thanks ... found it

I also ordered a set of coffee scales to improve the calibration process for the KHD and the dosers .... I guess it might also come in handy once my IonD arrives

In addition to putting the filter at the end of the sample tube I found tiewrapping the filter in a 25mm pvc tee helped the consistency (and kept the filter where I wanted it)

I found a standard graduated cylinder accurate enough to get whole number accurate but it would be interesting to know

Then I can only suggest raising a ticket to verify the probe is not faulty .... sorry

BTW my waste output is much less than reported too ... to answer the final question in your original post

So you've consumed 320ml of reference solution?

What sample volume are you using?

That's 10, 10, 10 and 10

Consistency is the key ... my KHD records between 9.5 and 10 testing twice a day. Recent Triton N-Doc test shows 9.8.

I could never get Hanna tester to agree so stopped using it.

If the KHD is...

I have a KH Director hooked-up to a Doser 2.1 and very happy

Just replumbed the dosing lines having relocated the kit to a cupboard

Consquently had a spike measurement I would like to delete as...

Same here with same negative result

Same issue for me .... no brush icon in the chart box

Ticket created - thanks for the response

Did the OP see a resolution to this issue?

After a couple of weeks of problem free connection I too have difficulty connecting via the app.

My Doser SA and my (non GHL) controller are...

I can't see any logical reason why connecting in access point mode or connecting through another access point would make any difference.

My SA Doser is connected to my router via WiFi, if I...

You can see graphical data on dKH measurements in the GHL connect app dashboard. You need to add the graphs tile and enable the sensor but it works.

Thanks Vinny that's good news - allows a gradual switch to GHL - i understand that future updates are difficult to predict but would that by any chance coincide with the ION Director launch?

The...

I read that as "it is not possible to see dosing history and KHD adjustments using a stand alone doser"

Thanks Vinny

When you say "see how involved the KHD becomes with adjustments" how do I get that information out of the doser?

I've been running my KHD now for nearly a week and everything is settling down.

Measurements are stable between 10.3 and 10.8 dKH which compares to stable readings on my Hanna Checker between 10.8...
