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
