The sensION156 is structured in six configurations for your convenience: pH/Conductivity, pH/Dissolved Oxygen, and pH/ Conductivity/Dissolved Oxygen. Depending on which configuration you order, the meter will come complete with a pH electrode, buffers (4.01 and 7.00), four AA batteries, a four-pole conductivity probe (1-meter cable) conductivity standard, a Dissolved Oxygen probe (1-meter cable), two DO membranes, filling solutions, beakers, a quick reference card, and an illustrated manual.
