CONTENTS 1 INTRODUCTION
The Model 2410 pH meter/simulator is a
battery-operated instrument designed for
measuring pH, Redox and temperature when
used with the appropriate sensors. It can also
be used as a simulator for injecting input
signals when servicing pH instruments.
The unit can inject any pH value from 0 to
14 pH and any millivolt value from –1000 to
1000 mV in 1 mV increments. A high
impedance output (1x10
9 Ω ) can be switched
into the circuit to simulate the resistance of a
glass electrode. A 100k
Ω reference check is
also available for detection of reference to
earth leaks.
