GENERAL DESCRIPTION
2. GENERAL DESCRIPTION
Partof Hanna Instruments pool-line family,HI981954 is awaterproof portable logging multiparameter
system (meter and probe), that monitors up to 11 different water quality parameters (5 measured,
6 calculated) such as pH, ORP, conductivity, and temperature.
The HI7698195 microprocessor-based intelligent multisensor probe can use the HI7698194-1 sensor
for pH and ORP (or the HI7698194-0 sensor for pH) measurements, and the HI7698194-3 sensor
for conductivity and associated parameters. The probe also has an integrated temperature sensor that
allows for automatic temperature compensation of pH, conductivity and is supplied with a removable
protective shield.
The HI981954 features a graphic, backlit display that automatically sizes the digits to fit the screen
with on-screen graphing capability. Each parameter is fully configurable.
HI981954 is a rugged instrument, the ideal solution for a variety of water quality measurements.
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.
Main Features
• Rugged, water-resistant meter and waterproof probe
• Monitors up to 11 different water quality parameters
• Graphical display of logged data on backlit LCD screen
• Auto recognition of the probe and field-replaceable, color-coded sensors
• Quick calibration feature
• Auto-ranging for EC readings
• Log-on-demand and automatic logging on meter for all parameters
• Dedicated help key for context sensitive help
• USB interface for PC communication
• Long battery life with alkaline batteries
• Good Laboratory Practice feature. Automatically stores the last 5 calibrations
