This PH-ORP 2000 is small in size, light
in weight, easy to carry. Although
complex and advanced, it is convenient
to use and operate. Its ruggedness will
allow many years of use if proper
operating techniques are followed.
Please read the following instructions

processing, clean or wastewater control and
neutralization processes. Though the construction
of the pH/ORP Controller complies with safety
regulations currently in force, improper use could
lead to hazards for the user or a third-party.
Therefore, the operating instructions must be read
and understood by the persons involved before
