Date Record RS485 Interface PH Water Analyzer For Water Quality Monitoring
DUC2-PH-S-D pH controllers all use imported chips and components, and the surface-mounted production process is adopted to ensure stable and reliable operation of the instrument;
Simultaneous display of multiple parameters: It can display pH value, temperature value, high alarm setting value, low alarm value at the same time Point alarm setting value, whether the meter is in high or low alarm state, and the current time.
All parameters are clear at a glance. The PH value corresponding to the unique 4-20 mA current output is reversible and can be set to any value, which can bring more special convenience to users. It adopts waterproof and gas-proof fully sealed shell, which can be used in very harsh environmental conditions, and the protection level reaches IP66.

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. Does the operation interface support customization?
Yes, our operation interface can be tailored to customers' needs.
Q4.Can our company's logo be added to your company's products?
Of course, we support OEM services for customers.
Q5.DO your controller with OTA function?
Yes. our DUC2-PH-S Controller with OTA function.
Q6.How long is the warranty period?
The company guarantees the instrument for one year (12 months) from the date of leaving the factory, and the consumables and wearing parts in the equipment are not covered by the warranty.
