Just for clarity so everyone has the right info on all units, the GHL Wifi Doser 2 comes with built in ATO AWC plus Temp, can in the future have any PAB device GHL makes connected to it, for example the possibility of power bars?. It also can be expanded up to 16 pumps, comes in a non rusting case. You can have just 1 pump if you really wanted.
German engineered and built
1-16 stepper motor pumps
ATO+AWC
Temp port
PAB port for future PAB device connections (Profilux Address Bus)
It also has 4 ports for stirrers.
WIFI Built in and USB port
port for future independent touch screen option
German built stepper motor driven
doses down to .01ml
plus 2 year warranty.
All APPS plus cloud based, and software
As GHL Doser 2 is Wifi built in it does not need the added expense of a bridge to get online. So when looking at the price points always take this sort of thing into account
It does not need a controller to run it either. The controller is your smart phone/device or computer
Just wanted to add for clarity so the whole debate is even and correct info shared.
I see that it started to be an advertisment thread, so to be honest with all above I want to clarify some important points about Kore 5th doser because some of above information's looks like little intentional misrepresentation by comparing the possibilities , but maybe I'm wrong
I think that we can compare GHL Doser 2 with Kore 5th PRO because they have similar prices(
GHL - 559,00 USD,
Kore - 539,00 USD)
1. Kore 5th is completly built and designed in Poland
2. Kore 5th have 5 very precise peristaltic pumps and doser can be expanded up to next 4 pcs pumps - total 9. I cant imagine any setup which will need more a specially that doser can do water changes(AWC) and ATO(refill) by included in set DC pumps.
Using included DC pump for ATO give us still possibility using all 5 peristaltic pumps.
If for ATO is used dosing pump - from original 4 pumps left only 3(so sure, slave can be needed). Additionally, if doser use peristaltil pumps for AWC+ATO work
only one dosing pump left for Customer. I think its VERY important information.
3. Kore have ATO+AWC funcionality not only built in - but also offer it from the beginning because this
set include all needed equipment - like
2pcs floating level sensors(up/bottom level) and
one optical sensor. Can ATO or AWC work(precisly) without level sensors?
Thats why Kore 5th include this sensors in set(without additional cost). This three level sensors can be connected to doser in the same time(can be configured as main ATO sensors, bottom/up level sensors, high water alarm sensors etc).
4. Kore include digitial temp sensor in price and it can monitor aquarium temperature(turning on/off sound alarm if its needed).
This temp sensor is include in set.
5. Kore 5th have digital input/output port for ANY future expension kits(like pH monitoring, relays,heater/aquarium cooler etc. First device which can be connected to this port is Magnetic Stirrer which was presented here:
http://www.advancedaquarist.com/blog/pacific-suns-kore-5th-magnetic-stirrer
and will be available since January 2015. MSRP = 99,00 euro.
All other modules/features are already in development - like special cooled container for dosing corals food(with auto emptying tubings from liquid after dose).
So limitations in the development are also limited only by the imagination

6. Kore work in Bluetooth communication layer, but
IF anybody will want to use it by internet(?) its possible to connect it via incoming Cube wireless bridge(BT<>Wifi).
7. Kore 5th resolution is 0.01ml which can be achieved using best quality Japanese DC motors. On this movie it's shown how precise they are(single dose 0.01ml - doser need three doses to "built" single drop):
http://www.advancedaquarist.com/blo...e-5th-dosing-pump-with-new-dropdose-dispenser
If GHL Doser 2 can work with the same resolution its very good and enough for aquatic industry(previously they shared info thats resolution is 0.1ml).
8. Two years of warranty and 5 years warranty for non-rusting cover(because its made from ferromagnetic stainless steel with powder coated layer).
Finally I have to agree with Michael:
"So when looking at the price points always take this sort of thing into account".
Both dosers have their own cons and pros a specially if we will compare what Customer can get "in package" together with doser(like all level/remp and for what he have to pay to be able use advertised funcionality.
GHL is proven and good known company but we see some actions which are atrying to depreciate our product(quality or included options).
I think that time will tell all, lets users rate this product.
"Just wanted to add for clarity so the whole debate is even and correct info shared."
Like always I really appreciate discuss with Michael from AquaDigital

Thank you.
