Full Description Specification

The HI-981954 is a waterproof portable logging multiparameter meter that monitors up to 9 different water quality parameters.

The multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, and temperature. The probe transmits readings digitally to the meter, where data points can be displayed and logged.

The complete system is simple to setup and easy to use.

Key Features

Calibration: Up to a three-point calibration with five standard buffers and one custom buffer available.

pH in mV option: Useful for diagnostics.

GLP data: Offset, slope, date, time and buffers used

Automatically temperature compensated readings

pH or pH/ORP field replaceable sensors: Gel filled and maintenance free plus double junction for reduced contamination of reference cell.

EC/TDS/Resistivity Features

Calibration: Single-point calibration from six standards

Temperature compensation: Automatic Temperature Compensation; Configurable temperature coefficient range from 0.00 to 6.00%/°C; Choice of reference temperatures at 20 or 25°C; Absolute conductivity can be displayed along with the temperature compensated value.

Auto-ranging

Salinity readings: Practical Salinity Scale (PSU) based on conductivity calibration.

Optional shockproof silicon rubber boot: Specially designed to protect your meter from damage or impact – HI-710034 Orange.

About the Backlit Graphic LCD Display

The HI-981954 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.

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.

GLP Data

HI-981954 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 characteristics.

Data Logging

The HI-981954 allows users to store up to 45,000 continuous or log-on-demand samples with logging intervals from one second to three hours.

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 experience.

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.

PC Connectivity

Logged data can be transferred to a Window’s compatible PC with the included HI-920015 micro USB cable and HI9298194 software.

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.

Rugged Custom Carrying Case

The HI-981954 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.

About the Quick Connect Digital Probe and sensors

The HI-7698195 is a multiparameter pH/EC/Temperature probe for use with the HI-981954 portable meter. It features a Quick Connect DIN that makes a waterproof connection with the meter.

It has colour coded, field replaceable sensors that are quick and easy to install with their screw type connectors that are colour coded for easy sensor port identification.

Sensors are automatically recognised by the probe and meter when connected. Any ports not used on the probe will not have the parameter displayed on the meter.

Sensor replacement is quick and easy with field replaceable, screw type connectors that are colour coded for easy sensor identification. The probe features a multistrand-multiconductor shielded cable with 4m, 10m, 20m, and 40m lengths available. It’s rugged, waterproof design makes it ideal for field use.

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.

Auto-sensor Recognition

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

Automatic Temperature Compensation

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