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

Electronic Comparison on NAPT Samples

The Labfit Robotic system 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

Future AS-3000 Upgrades

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.
