Data Record Digital PH Meter With Two SPST Relays For Industrial Processing Control
This set of digital PH/ORP analyzer is developed and produced based on digital requirements. It is divided into two basic models: potentiometric PH glass electrode and platinum ORP electrode.
When the meter is connected to a pH electrode with temperature compensation function, this menu needs to be set according to the type of temperature electrode. If you need to manually input the compensation temperature, you can select "Manual Compensation" and set the manual compensation temperature.
The instrument acts as a slave on the network and supports Modbus RTU communication protocol.

FAQ
Q1. Does the instrument have a self-diagnostic function and how
does it prompt?
A: The pH meter has self-diagnosis function.When the instrument is
in calibration and maintenance,it can diagnose the PH/ORP sensor,if
there is improper operation or poor PH/ORP sensor characteristics,
the screen makes an image display and advises the user to
re-maintain or replace the sensor.
Q2. What are the special advantages of the pH instruments?
A: The instrument can not only compensate the temperature of the
test sample by connecting the temperature sensor, but also
self-check the working temperature of the instrument in real time.
When the working temperature of the instrument changes, the
instrument compensates the hardware change caused by the
temperature drift. Make the test results more accurate, this is a
patented technology.
Q3: Is there any stock?
A: Yes,we have materials in stock to help you to get the samples as
soon as we can
Q4: How to track my Order?
A: After shipped, we will email you the tracking number.
Q5: How about warranty ?
A: Warranty: 12 months, Lifetime maintenance
Q6: How about after-sales service?
A : We are 24 hours online, if you have any problem,pls contact us
directly.
Q7: Any discount?
A : For bulk purchase or distribution agents, we will apply the
