1. Safe precautions

Please follow the operating procedures and
precautions of this manual when using
Do not power on before wiring is completed to

avoid danger.
If you find that the instrument works abnormally

or is damaged during use, please contact us
instead of repairing it yourself.
In order to make the measurement more

accurate, the meters must be calibrated
frequently with sensors.
If your electrode has been purchased for nearly

a year or there is a quality problem with the
electrode, please replace it.
Please power on the instrument to warm up for

30 minutes before calibration.
If the product is updated, this manual may be

changed, but we will not notice.

5. Product Introduction

The pH digital sensor designed by our company for
the aquaculture industry, with a digital interface
(RS485*1), can be used to measure changes in the
pH/ORP value of the aqueous system within the
range
It has a standard RS485 Modbus RTU protocol
interface function, which can communicate with the
host computer remotely
