Portable pH and ISE Meters
Information
Orion’s Portable Meters are compact, battery operated and
microprocessor
controlled for all measurement needs. All meters feature a
custom digital
LCD display, which simultaneously displays temperature along
with
measurement results. Ideal for field, plant, or laboratory
use, each meter is
lightweight and designed to fit comfortably in the hand.
A flip stand allows easy use in the lab.
The Orion 210Aplus is a basic pH meter that features 2 point
autocalibration.
The Orion 230Aplus is a pH meter that features
autocalibration and
automatic temperature compensation, millivolt, relative
millivolt and (EH)
ORP mode.
The Orion 250Aplus has all the features of the 230Aplus plus
3 point auto
calibration and RS232-C output for use with the Orion 900A
printer or
other serial peripherals.
The Orion 290Aplus adds concentration measurements and an
internal
datalogging function to make a truly versatile meter for pH
or ISE analysis.
This manual contains instructions for all four meters. See
the calibration
and measurement section for details on your particular
meter. The general
information section contains descriptions of hardware which
pertain to all
meters. The Temperature Compensation and Troubleshooting
sections
contain information applicable to all meters.
