SHANGHAI BOQU INSTRUMENT COMPANY

PHG-2091 Online pH / ORP Analyzer is one of the intelligent online chemical analysis

instruments, is a widely used in thermal power, chemical fertilizer, metallurgy, environmental

protection, pharmaceutical, biochemical, food and tap water solution PH value or OPR Value and

temperature of the continuous monitoring.

Continuous monitoring data through the transmission output connection recorder to achieve

remote monitoring and recording, you can also connect the RS485 interface through the

MODBUS-RTU protocol can be easily connected to the computer to achieve monitoring and

recording.

Board modular design, assembly configuration more convenient.
