The AS-3000 pH & EC Analyzers
The Benefits of Automation in General






Reduced labor costs
No staffing issues – sick, holidays etc.
High throughput of samples > ~ 20,000 samples/yr
Only accepts results from programmable settings
Very low cost for Automation
Capital expenditure quickly amortized
Why the AS-3000’s?
The LabFit automated AS-3000 analyzer provides
consistent results and eliminates inherent operator
errors which are unavoidable doing pH & EC’s
manually.
Each sample is consistently handled in exactly the
same manner.
It will only record results according to
programmable settings

reduces potential errors from
manual pH determinations

How the Method Works





AS3010D will analyze all samples for pH & buffer
without technician intervention
pH’s are determined before buffer determination
Buffer is added and stirred while pH is being read in
adjacent row
Buffer reaction time with soil is determined by
individual laboratories
After reaction time, the AS3010D automatically reads
the buffered samples


New Control Box to increase speed
Completely new software package
Easier to use and configure
New 10 probe pH analyser within the
next few months
AS-3000 Upgrades

A new Control Box without a PLC. The benefit will be that
there will be no more delays between movements, ie it will
be faster. Also no more PLC problems, losing it’s brain etc.

A completely new software package not using Citect. Much
simpler system. Easy to use human interface, but with
more functionality.
