Introduction to PHG-2 Industrial Acidity Meter

The PHG-2 online pH acidity meter is a dedicated acidity meter for the industrial field. It has built-in imported high-quality chips and components, which ensures that the PHG -2 industrial acidity meter has good stability and reliable measurement data during long-term testing. Its resolution is 0.01pH. The PHG-2 industrial acidity meter has dual functions of PH/ORP and can be freely converted to meet the needs of different users. Its automatic correction and temperature compensation functions greatly reduce operating procedures.

PHG-2 online pH acidity meter is suitable for acidity detection in industrial sewage pools. It is Orilon's main industrial acidity meter product.

Features and advantages

1. PHG-2 industrial acidity meter has built-in imported chips and components to ensure long-term stable and reliable operation of the instrument;

FAQ
QWhat industrial scenarios is this pH meter suitable for?
A PHG-2 is particularly suitable for wastewater monitoring in chemical, Eletroplating or printing and dyeing plants, because its isolation signal output and relay control can resist interference, and it can also automatically adjust the water quality in conjunction with dosing equipment.
QWhich one do you need to measure PH and ORP values at the same time?
A Select PHG-2 on the line, it can switch the PH/ORP dual mode with one key, the operational amplifier has high accuracy, and the positive and negative values are symmetrical when measuring the Oxidation-reduction potential, and the data is more accurate.
QWhat pH meters can be used for industrial wastewater treatment?
A PHG-2 industrial on-line pH meter is designed for industrial wastewater with automatic temperature compensation and antimony electrode mode, which can stably monitor the acid and alkalinity changes of sewage tanks.
QDo you need to calibrate the ph meter before each use?
A Twice a week.
QIs there an industrial online pH meter with GB/T11165 standard?
A This AOLILONG industrial online pH meter is fine!
