INTRODUCTION
This Sper Scientic Water Quality Meter (Model 850081)
uses optional, interchangeable probes to read pH, millivolt
(mV)/ oxygen reduction potential (ORP), conductivity, total
dissolved solids (TDS), salinity, dissolved oxygen (DO) and
temperature with optional probes. Order only the probes
required for your current parameters and add additional
probes in the future.
All probes are optional and not included with the meter.
The meter automatically recognizes pH buers 4, 7 and 10
for simple calibration. Other features include readings in
°C or °F, automatic temperature compensation (ATC) and
salinity and altitude compensation for DO measurements.
An RS232 port enables communication with a computer.
Additional features include automatic shuto, minimum
and maximum values, a fold-out easel back and a tripod
mounting screw.
