Backlit Graphic LCD Display

The HI981954 features a backlit graphic LCD
with on-screen help and the capability to
display up to nine parameters simultaneously.
The graphic display allows for the use of virtual
keys to provide for an intuitive user interface.

Automatic Temperature

Integrated temperature sensor allows for
automatic temperature compensation of pH
and conductivity measurements.

Waterproof Protection

The meter is enclosed in an IP67 rated
waterproof casing and can withstand
immersion in water at a depth of 1 m for up
to 30 minutes. The probe features an IP68
rating for continuous immersion in water

Dedicated Help Key

Contextual help is always available through a
dedicated “HELP” key. Clear tutorial messages
and directions are available on-screen to
quickly and easily guide users through
setup and calibration. The help information
displayed is relative to the setting/option
being viewed.

GLP Data

HI981954 includes a GLP feature that allows
users to view calibration data and calibration
expiration information at the touch of a key.
Calibration data includes date, time, buffers/
standards used for calibration, and slope

PC Connectivity

Logged data can be transferred to a Window’s
compatible PC with the included HI920015
micro USB cable and HI9298194 software.

Quick Connect Digital Probe

The HI7698195 probe features a Quick
Connect DIN connector that makes a
waterproof connection with the meter.

Long Battery Life

The display of the meter has a battery icon
indicator to show the remaining power.
The meter uses four 1.5V AA batteries that
provide up to 360 hours of battery life.

Color Coded, Field Replaceable

Sensor replacement is quick and easy with field
replaceable, screw type connectors that are
color coded for easy sensor port identification

Data Logging

The HI981954 allows users to store up
to 45,000 continuous or log-on-demand
samples with logging intervals from one
second to three hours.

Standard or Quick Calibration

Quick Calibration provides a speedy, single
point calibration for pH and conductivity.
Standard pH calibration options are available for
calibrating up to three points from a selection
of five standard buffers and one custom buffer.
Conductivity calibration is a single point from six
standard selections or one custom standard.

Intuitive Keypad

The fitted rubber keypad has dedicated keys
for power, backlight, up/down arrows, help
and alphanumeric characters. The meter also
features two virtual soft keys that navigate
the user through the configuration of each
parameter, meter setup, and logging of data.
The interface is intuitive for any user’s level of

Auto-sensor Recognition

The probe and meter automatically recognize
the sensors that are connected. Any ports not
used on the probe will not have the parameter
displayed or be configurable.

Rugged Custom Carrying Case

The HI981954 meter, probe, and all accessories are supplied in a rugged carrying case designed to provide years of use. The inside compartment of the carrying case is thermoformed to securely hold and protect all of the components.
