You’re not wasting it if you’re using the KHD to control and keep your kH stable 
If you’re just monitoring, I suppose you could consider it being wasted, in future firmware this will be addressed, this is only an issue for a Doser/KHD combo, if you’re using a ProfiLux, this is not an issue.

Sorry guys but I am going to step in here and say that my KH Director is happily recording my KH values @ 4 times per day. I have a happy little trend of the last 12 days roughly. For whatever reason it took 2 days before i could see the trend in myghl but it as worked perfectly ever since. I am very curious to know what the bubbles are in the reagent line but i have managed to get past this by keeping the line extremely short, only very tiny bubbles are generated before they go through the director. The blip on my trend is me tinkering.
@dragon99 I cannot complain about the unit. It works perfectly fine although there really should be more documentation for setup and control including pictures. Just make sure that the first thing you do is to update the firmware on all the equipment, nothing worked correctly for me until i did that, once that was done no more issues and to be honest i have no regrets buying the unit at all. I work away from home for 3 months at a time so for me this is a lifesaver.

True, that's the primary reason for having it. But I like pretty graphs. Always better to be informed than just have to trust that a device is working.You’re not wasting it if you’re using the KHD to control and keep your kH stable

Oh yes for what it is worth I actually have my unit altering the dosing.........I didnt have the luxury of spending time monitoring and playing with the system before going live. It has worked very well. I would have preferred a true PID loop for the dosing but GHLs method seems to work just fine.

An update on my first month... as can be seen below my readings are relatively stable, the blips although frustrating are now explainable, some being caused by bubbles forming in the reagent which is well documented, I put a new bottle on a few days ago and there does seem to be less bubbles forming, I don’t know whether this is a change in manufacturing or less temp swings etc in storage and transport. A major own goal I was scoring was as my waste container filled it covered the end of my vent tube, which causes the major reading errors seen, again I think this is documented enough now so others keep them well above the maximum fill level. I have found a consistant discrepancy between KHD and Hanna phosphorus ULR readings, over the entire month and dozens of readings on both hanna and KHD and my KHD reads a consistent 0.6 DKH lower than the hanna, and I even changed hanna reagents to double check as there can be some variance in those and I saw exactly the same readings, my conundrum now is which is correct? I have now set my KHD with a +10% reading so that they are the same now. As long as there consistent I’m not that concerned but I am wondering if I’m running at 6.5 or the 7.1 I want? I am going to get some other test kits to verify readings, and go from there. My data has always been recorded, but I downloaded the latest software before installing.

We should see more of them go out today/tomorrow, we received 1 pallet today, and another should be delivered by tomorrow. Depending on where your pre-order falls in line, I think the majority of pre-orders will be fulfilled with both of these shipments.
Are you in our Facebook group? We have been posting updates in there as well.

We're hoping for the pallet delivery early in the day, TODAY.
As long as the pallet arrives before 3PM, we're hoping to get the majority shipped out by Wednesday.
To our disappointment; the pallet was not picked up from Customs hold by the carrier until Friday mid day. I guess if the UK can't have KFC Chicken, we can't have KHD's.

I can check, I ordered the white slave doser khd combo a week or so before Thanksgiving. Problem is there's several different combos. Black, white, slave, stand alone. I will check though
Looks like order #2013. I'll keep my fingers crossed for ya, and everyone else! Hopefully the 2 pallets that came in within the last week get everyone taken care of!

I did the same accept in black. About the same time period so hoping to get my notice real soon too. Thanks.
