Overview
QIWEI PH-110/PH-110A/PH-110AS online pH Meter is an industrial online pH Meter, used for continuous measurement and control of sewage pH value, pH/ORP measurement, upper and lower limit control, current output, digital communication and password management functions. LCD display, real-time observation of data. Among them, PH-110 is a common type, PH-110A has temperature compensation function, PH-110AS has temperature compensation function and can perform data extraction and connection to computer.
Features
1. Can perform pH/ORP measurement, upper and lower limit control, current output, digital communication
2. Factory standard configuration Chinese interface, language menu, can be switched between Chinese and English
3. pH high limit alarm, low limit alarm dual-channel relay, hysteresis can be adjusted freely
4. Can be set to automatic temperature compensation or manual compensation
5. PH-110/PH-110A/PH-110AS pH meter mode isolation transmission port, the maximum loop resistance is greater than 300Ω
6. Audio alarm can be switched on and off, set on or off through interface options
7. The LCD backlight can choose the energy-saving mode and automatically turn off regularly
8, high performance CPU, good electromagnetic compatibility performance
9. Password management function to prevent misuse by non-professionals
Principle
The in-line pH Meter performs pH/ORP measurements via Measurement Electrode (red interface) and Reference Electrode (black interface), supports temperature compensation (manual or automatic), and processes data via a high-performance CPU for continuous measurement and control.
Applications
Continuous measurement and control of pH value
Standards
PH standard solution: 4.00/6 86/9.18
Steps
1. Place the controller in front of the panel
2. Install the upper and lower two fixing clips
3. It can be fixed by locking it with a screw batch.
Notice
• The power interface is 220V, make sure to connect the L and N interfaces correctly
• Temperature compensation interface TEMP1 and TEMP2 for temperature compensation
• Measurement Electrode connection INPUT interface, reference Electrode connection REF interface
• 485 Communication interfaces A and B for digital communication
• 4~ 20mA output terminal connected to mA + and mA-, maximum loop resistance 300Ω
• High and low alarm touch points connect LO and HI interfaces, pay attention to normally open touch points
• Do not connect if the interface NC is not defined
• Permissible Ambient Temperature 0~ 60 ℃, relative humidity ≤ 85% RH
• Use the password management function to prevent misoperation
