SECTION 1 INTRODUCTION
This manual describes the operation and use of the Hach
sens
ion
™
1 Portable pH/mV/Temperature Meter (see Figure 1).
This meter features a custom digital LCD display which
simultaneously shows temperature and measurement results. This
meter has all the features of a simple pH meter plus a millivolt
mode, IP67 waterproof design, electrode holder, ergonomic
design, and automatic buffer recognition.
The electrode holder on the back of the instrument allows the user
to store the electrode and meter in one convenient package when
not in use. The electrode holder is designed so the user can slip a
vinyl electrode cover over the electrode tip, creating a humid
environment that allows the electrode membrane to remain
hydrated when not in use (see Figure 2 Electrode Holder).
The meter is designed to be maintenance-free. If the meter gets
dirty, wipe the surface with a damp cloth. Use a cotton-tipped
applicator to clean or dry the connectors if they get wet.
