Online acid-base concentration meter, conductivity meter, resistivity
Liquisys M OLM223 and OLM253 conductivity meters adopt modular design and are widely used. The basic transmission provides simple measurement and alarm functions, and the software and hardware modules for extended functions can be applied to special occasions. If necessary, expansion modules can be used.

Characteristics and advantages of German AMER acid-base concentration meter
Inductive principle, measuring the concentration of acids, bases, salts, etc. dissolved in liquids
The contact can be set as USP alarm (pre alarm/adjustable)
Directly enter manual contact control, the contact can be set as USP alarm (pre alarm/adjustable)
Scalable basic units:
Two or four contacts are used for:
-Limit contact (also used as temperature)
-P (ID) controller
-Timer for flushing process
-Complete chemical cleaning
Extended software package
-Any current output configuration
-Alarm or timed start of automatic cleaning
-Ultra pure water monitoring system, compliant with USP 23 (limited conductivity sensor)
-Polarity detection (limited conductivity sensor)
-Concentration measurement (%/TDS)
-Compensate for temperature through a table
-Online inspection of measuring units
HART communication protocol
The second current output is used for temperature
