Big Discount Diy Salinity Meter - Online pH/ORP Meter T4000 – Chunye

Function

Industrial on-line PH/ORP meter is an on-line water quality monitoring and control instrument with microprocessor.

PH electrodes or ORP electrodes of different types are widely used in power plant, petrochemical industry, metallurgical electronics, mining industry, paper industry, biological fermentation engineering, medicine, food and beverage, environmental water treatment, aquaculture, modern agriculture, etc.

The pH (acid, alkalinity) value, ORP (oxidation, reduction potential) value and temperature value of aqueous solution were continuously monitored and controlled.

Typical Use

The instrument is equipped with different types of pH or ORP sensors. Widely used in power plants, petrochemical industry, metallurgical electronics, mining, paper industry, biological fermentation engineering, medicine, food and beverage, environmental protection water treatment, aquaculture, modern agricultural planting and other industries. The pH (acidity and alkalinity) value, ORP (redox potential) value and temperature value of water solution were continuously monitored and controlled.

Features

1.Color LCD display
2.Intelligent menu operation
3.Multiple automatic calibration
4.Differential signal measurement mode, stable and reliable
5.Manual and automatic temperature compensation
6.Two relay control switches
7.4-20mA & RS485,Multiple output modes
8.Multi parameter display simultaneously shows – pH/ORP, Temp, current,etc.
9.Password protection to prevent misoperation by non-staff.
10.The matching installation accessories make the installation of the controller in complex working conditions more stable and reliable.
11.High & low alarm and hysteresis control. Various alarm outputs. In addition to the standard two-way normally open contact design, the option of normally closed contacts is also added to make the dosing control more targeted.
12.The 3-terminal waterproof sealing joint effectively prevents
water vapor from entering, and isolates the input, output and power supply, and the stability is greatly improved. High resilience silicone keys, easy to use, can use combination keys, easier to operate.
13.The outer shell is coated with protective metal paint, and
safety capacitors are added to the power board, which improves the strong magnetic anti-interference ability of industrial field equipment. The shell is made of PPS material for more corrosion resistance. The sealed and waterproof back cover can effectively prevent water vapor from entering, dustproof, waterproof, and corrosion-proof, which greatly improves the protection capability of the whole machine.

Electrical connections

Electrical connection The connection between the instrument and the sensor: the power supply, output signal, relay alarm contact and the connection between the sensor and the instrument are all inside the instrument. The length of the lead wire for the fixed electrode is usually 5-10 meters, and the corresponding label or color on the sensor Insert the wire into the corresponding terminal inside the instrument and tighten it.
