INTRODUCTION
This Sper Scientic Dissolved Oxygen Meter Kit (Model
850081DOK) comes with dissolved oxygen (DO) probe
(850081DO) and also uses optional, interchangeable probes
to read pH, millivolt (mV)/ oxygen reduction potential (ORP),
conductivity, total dissolved solids (TDS), salinity, and
temperature. Order only the probes required for your current
parameters and add additional probes in the future.
Only 850081DO probe comes with this kit. Other Probes
are optional.
The meter features include readings in °C or °F, automatic
temperature compensation (ATC) and salinity and altitude
compensation for DO measurements.
Additional features include automatic shuto󰀨, minimum
and maximum values, a fold-out easel back and a tripod
mounting screw. Automatically recognizes pH bu󰀨ers 4, 7
and 10 for simple calibration when using optional probes
