The Model SC72 Personal Conductivity Meter is an accurate, portable, easy-to-use
conductivity meter. It includes not only self-diagnostic functions, to help ensure validity
of readings, but also data storage functions to allow users to check past data. The meter
is of waterproof construction so that it can safely be used outdoors on a rainy day, and
can also withstand being accidentally dropped into water.
1.1 Features
Water resistant case
When this meter is used with its dedicated sensor, it meets the requirements of class IP67
“Degree of Protection to be Provided by Enclosures” in IEC 60529.
Wide measurement range, and convenient “Auto Range” function
Sensors are available to cover measurement ranges between 0 to 2.000
␮S/cm and 0 to 2
S/cm. Auto-range functions automatically set the optimum measurement range, making
measurement easy.
Automatic temperature compensation
Automatic temperature compensation functions are provided for liquid measurement.
Conductivity referenced to 25
؇C can be obtained in solutions with temperature
coefficients between 0.00 and 9.99%/
؇C. The temperature coefficients for NaCl solutions
are already stored in the meter.
Calendar and time functions
Internal time functions allow “one-touch checking” of measurement date and time.
Data storage function
Up to 300 conductivities and temperature measurements, and their measurement date and
time, can be saved. This function allows you to check past measurement data.
Automatic power off function
The meter will power off automatically if not operated during a preset time interval.
The time interval can be set in one-minute increments in the range 1 to 120 minutes to
meet your application requirements. This automatic power off function can also be
disabled, but it is wise to leave it enabled to conserve the batteries.
Simple alarm clock function
The meter can issue an alarm signal at a specified time. Even when meter power is
turned off, the internal clock can issue an alarm signal.
Internal self-diagnostic functions display messages when appropriate.
Bright easy-to view large LCD
Displays liquid conductivity, liquid temperature, temperature coefficient, date and time.
