Before using this product, make sure that it is entirely suitable for your
specic application and for the environment in which it is used.
Operation of this instrument may cause unacceptable interferences to other
electronic equipment, thus requiring the operator to take all necessary steps
to correct interferences. Any variation introduced by the user to the supplied
equipment may degrade the instrument’s EMC performance.
To avoid damages or burns, do not put the instrument in microwave ovens.
For your and the instrument’s safety, do not use or store the instrument in
hazardous environments.

Description

edge™ enables the user to make fast, accurate measurements of commonly
measured laboratory parameters using one of the Hanna edge™ digital
sensors for pH, Conductivity or Dissolved Oxygen. The digital sensors are
individually serialized and identied by the meter. Once connected to the
meter, they are ready to measure their individual parameters along with
temperature.
The clean user interface permits you to adapt edge™ to your exact
measurement requirements. The intuitive design simplies conguration,
calibration, measurement, data logging and transfer of data to a USB thumb
drive or computer. edge™ also oers a basic operation mode that streamlines
measurement conguration and is useful for many routine applications.
Every feature and measurement detail is designed to give you an edge in
measurement technology.
edge™ is versatile in many ways. The slim meter and probe can be used
remotely as a portable device (using its rechargeable battery) or used in its
bench or wall cradles (that also power the meter) as a line-powered laboratory
instrument.

The main operating modes of edge™ are setup, calibration, measurement,
data logging, and data export. Follow this general outline of steps to get you
started in taking measurements. The following topics are expanded upon in
the sections that follow in this manual.
1. Familiarize yourself to the design features of this unique meter.
2. Decide how the meter will be used and set up the wall or bench cradle in
a clean area near line power.
3. Turn edge™ on using the ON/OFF button located on the top of the meter.
4. Plug in the probe required for measurement.
5. SETUP the measurement parameters required for the measurement you
will be making.
6. Calibrate the sensor/probe.
You are now ready for measurements.
Bench Cradle Setup

socket. edge™ can be also powered by
connecting with a USB cable directly to
a PC.
Note: edge™ is supplied with a
rechargeable battery inside, which
ensures about 8 hours of continuouse
use. Whenever edge™ is connected to
the power adapter or to a PC, the battery
is recharging.
Connect the connector of the probe to
the probe input located on the bottom of
edge™. Make sure the probe is completely
connected. If the probe is recognized,

edge™ oers a basic operation mode that streamlines measurement
conguration for pH and EC measurements and is useful for many routine
applications. Basic pH SETUP reduces parameter selection to the basic set.
The meter limits calibration to 5 standard pH buers; 6.86, 7.01, 4.01, 9.18
and 10.01 buers. All pH measurements will display, log and export with 0.01
pH resolution. Interval logging is also eliminated. Manual and Manual stability

meter defaults setting to common parameters and auto ranges measurements
automatically. The Basic EC meter may be used for conductivity and TDS
measurements (salinity is not available). Interval logging is also eliminated.
Manual and Manual medium stability Log on demand are still functional.
Note:
• If powering edge™ through the micro USB connector to a PC, a SETUP
parameter will require the choice “LOG ON EDGE”.
• 1000 log records can be stored into the Edge memory. This memory
is shared between all measurement types (pH, EC, DO) and all logging
types (Manual, Manual Stability, Interval logs)
• The maximum number of records for an Interval Lot is 600 records
(provided log space is available).
The maximum number of Interval Lots that may be
stored is 100. If a 101st lot is attempted, “MAX LOTS”
will be displayed. Some lots will need to be deleted.
The lot numbering is up to 999 and restarts if all LOT
logs are deleted. The maximum number of records
that may be stored in a MANUAL or STABILITY lot is
200 records.
If the log memory is full during any logging session,
the “LOG FULL“ message will be displayed on the 3rd

Basic vs
Standard
pH mode
For optimum pH measurements, follow these steps:
1. Understand the benets and features of Standard and Basic Operation.
2. Set up edge™ meter by conguring preferences.
3. Calibration
4. Measurement
The “Standard” pH operation includes up to a 5-point buer calibration, use
of custom buers, choice of displaying 0.001 pH resolution, use of the full
diagnostic features of Calibration Check™ (that includes buers used, probe
condition, response time and messages indicating a contaminated buer
or pH sensor requiring maintenance during calibration). Additional Sensor
Check™ indicators are available if using HI 11311 or HI 12301 pH electrodes.
These include a continuous diagnostic to detect if the electrode is broken
or the reference junction has been compromised by sample contamination
or fouling. The Standard pH operation also includes full logging capability
including Interval, Manual log on demand and Manual log on stability.
“Basic” pH operation provides a simplied SETUP menu; there are no decisions
to make regarding the pH measurement itself. The meter will display 0.01
pH resolution and permit a 3-point buer calibration from the following
pH buers; 4.01, 6.86, 7.01, 9.18 or 10.01. Calibration Check™ and Sensor
Check™ features are limited to messages during calibration. Calibration
reminders are also not available. The GLP will still provide oset, slope,
buers used and a calibration date. The Basic pH operation includes Manual
log on demand and Manual log on stability (medium setting).
Note: When changing from Standard to Basic operation in SETUP, previous
calibration data will be cleared. A prompt will force the user to facilitate this.
