Module FLXA21
Thông số kỹ thuật Yokogawa FLXA21
■ Measurement
Object/Sensor
Type
• pH/Oxidation-reduction Potential (pH/ORP) (analog
sensor)
• Conductivity (SC)
• Inductive Conductivity (ISC)
• Dissolved Oxygen (DO)
• pH/Oxidation-reduction Potential (pH/ORP) (digital
sensor)
Note: The
available
measurement
object
depends
on a
sensor
module
installed
on the analyzer.
