HI 991300 and HI 991301
pH/EC/TDS MULTIPARAMETER METERS
HI 991300 and HI 991301 have been designed to offer you pH, electrolytic-
conductivity, total dissolved solids and temperature measurements all in a slim,
lightweight, portable unit. For greater precision in your application, both models are
available, each with different conductivity ranges. From purified to brine waters,
just choose the model for your range of measurement.
The HI 1288 pre-amplified multiparameter probe features an easy to clean flat tip
sensor and a cloth junction that can be pulled longer to increase the life of the probe.
User selectable features include different TDS factors from 0.45 to 1.00, and a
range of temperature coefficients (ß) from 0.0 to 2.4% for greater consistency
and reproducibility.
These instruments easily fit in the palm of your hand and the bottom probe connection
ensures the electrode cable doesn’t get in your way. The large, multi-level LCD
displays the primary reading, temperature and calibration guides simultaneously.
• Waterproof to IP 67
• Multi-level LCD display
The meters display the current
measurement simultaneously with
the current temperature. A quick-
guide is also displayed to aid users
in instrument operation.
• HOLD
The Hold button freezes readings
on the display for manual recording.
• Automatic Temperature
Compensation
• Automatic 1 or 2 point calibration
• BEPS
BEPS (Battery Error Prevention
System) alerts the user in the event
that low battery power could
adversely affect readings.
• Battery % displayed on startup.
• Heavy-duty
The enclosure of these waterproof
meters are made of tough ABS
plastic for harsh environments.
• Easy to clean and keep clean
