AMER online pH/ORP meter from Germany, produced in Germany with quality assurance.
The Liquisys M OPM223 and OPM253 online pH/ORP meters adopt modular design and are widely used. The basic type of pH meter transmitter provides simple measurement and alarm functions, and after modularization of software and hardware, it can be applied to special occasions. If necessary, expansion modules can be used.

application
sewage treatment
Neutralization
Detoxification (electroplating)
water treatment
hydrological monitoring

FEATURES AND BENEFITS
On site installation or disk mounted transmitter
general use
- pHValue and oxidation-reduction measurement（mVperhaps%）It can be cut off through software switches
Simple operation
-Reasonable menu style structure, displayed in six languages, making configuration more convenient
-Two line display can simultaneously display measurement values and temperature
-Calibration is simple, with the help ofCALKey implementation for two-point calibration
Use safety
-Overvoltage (lightning) protection, compliant withEN61000-4-5standard
-Manual contact output control
-Rationality testing of calibration
-User defined configuration of alarm contacts and fault currents
Scalable basic units:
2A or4A contact point is used for:
-Limit contact (also used as temperature)
- P(ID)controller
-Timer for flushing process
