Phg-2250 industrial pH meter is an intelligent upgraded product of
industrial pH meter, which can continuously measure and control
the pH value of sewage. This device is applicable to urban sewage
treatment plant, chemical industry, printing and dyeing, paper
making, pharmaceutical industry, electroplating, environmental
protection and other fields.
According to the environment and characteristics of the water
industry, combined with the international power supply standard,
the
electrical design code for special environment is considered, and
the selection of 220V AC (phg-2250a) and safe low voltage 24V
AC, 24V DC (phg-2250b) power supply is added.
Main features:
128 * 64 lattice LCD, large screen dual channel display
Three configuration modes: dual pH, dual ORP, one pH and one ORP
Factory standard configuration Chinese interface, language menu
It can measure the pH / ORP of two channels, control the upper and
lower limits
It can be set to automatic temperature compensation or manual
temperature compensation
PH high limit alarm, low limit alarm two-way relay, the hysteresis
can be adjusted freely
The audible alarm can be switched on and off through the interface
options
LCD backlight can choose energy-saving mode and turn off
automatically at fixed time
High performance CPU, good EMC performance
Password management function to prevent misoperation of non
professionals
