PHG-3081 Industrial PH MeterDetailed product description：

The PHG-3081 industrial pH meter is the latest generation of high-end instrument with Chinese (English) microcomputer, featuring Chinese (English) display, single operation, full intelligence, multifunctionality, high measurement performance, and strong environmental adaptability. This table is a highly intelligent online continuous monitoring instrument, consisting of two parts: sensors and secondary meters. Can be equipped with three composite or two composite electrodes to meet various usage scenarios. It can be widely used for continuous monitoring of pH values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

Characteristics of PHG-3081 Industrial PH Meter:
New layout design, cast aluminum shell, metallic texture, creating a high-end E-era water instrument!
Simple menu structure and text-based dialogue: Compared with traditional instruments, DOG-2082 has added a lot of functions, but due to the use of a categorized menu structure and microcomputer like operation methods, it is clearer and more convenient to use. No need to memorize the operation steps and sequence; You don't need an instruction manual, just follow the prompts on the screen to operate.
Intelligence: Adopting high-precision AD conversion and single-chip microcomputer processing technology, it can complete various functions such as pH and temperature measurement, automatic temperature compensation, and instrument self checking.
Reliability: Components are integrated onto a single circuit board, eliminating the need for complex functional switches, adjustment knobs, and potentiometers.
Dual high impedance input: using the latest devices, the dual high impedance input impedance is as high as 1012 Ω, with strong anti-interference ability;
Solution grounding: eliminate interference from the grounding circuit.
Current isolation output: using photoelectric coupling isolation technology, strong anti-interference ability, and can be transmitted remotely;
Communication interface: It can be easily connected to a computer for monitoring and communication.
Automatic temperature compensation: Automatic temperature compensation within 0-99.9 ℃.
Waterproof and dustproof design: protection level IP54, suitable for outdoor use.
Adopting a menu structure, similar to microcomputer operation, the operation is simple, with Chinese prompts throughout the operation steps, and can be easily completed without the need for an instruction manual.
Multi parameter screen display: Display pH value, input mV (or output current), temperature, time, and status on the same screen.
