Yokogawa SC72 Personal Handheld Conductivity Meter - Manual (Page 11)

IM 12D03D02-01E 1-6
1. Outline
1.6 Sensor Part Names and Functions
Four types of sensors are available for use with the Model SC72 Personal Conductivity
Meter:
(1) sensor for high purity water measurement (cell constant 0.05 cm -1 ),
(2) general-purpose sensor (cell constant 5 cm -1 ),
(3) chemical-resistant sensor (cell constant 50 cm -1 ), and
(4) sensor for high-conductivity measurement (cell constant 50 cm -1 ). Check the model
number and cell constant on the name plate to confirm which type of sensor you
have.
