SECTION 1

INTRODUCTION

The versatile sens

ion

™8 Dissolved Oxygen Meter, shown in

Figure 1, easily measures dissolved oxygen in aqueous solutions.

Important features include measurement in % saturation;
autocalibration; a 99-point internal datalogging function; and
altitude, barometric pressure, and salinity correction. The meter is
microprocessor-controlled, has a sealed keypad, and can send
data to a printer or computer.

The DO probe can also be equipped with the available BOD
apparatus kit which allows it to be used in conjunction with an
electromagnetic stir stand for BOD measurements.
