Oakton ® Acorn Ion 5 and Ion 6 Meters

Oakton ® Acorn  Ion 5 and Ion 6 Meters

Direct readout of ion concentration units
mV measurement mode allows you to check electrode performance.
Compact size fits right in pocket.

±500 mV range is compatible with almost all ISE electrodes.


These rugged, economical meters are very easy to use. Choose from two models. Both feature hold and auto-off functions, splash-resistant keypad and large LCD.
Meters include four AAA batteries, instructions, and a protective rubber boot which offers sturdy protection for meter and acts as meter stand for benchtop use.

Ion 6 Meter measures ion concentration (in ppm), pH, mV and °C.
