OTA Online PH Transmitter with two settable 0/4~20mA current outputs
DUC2-PH-H-A pH transmitter is the latest intelligent integrated industrial transmitter developed by our company. It adopts a new design mode, high performance, high reliability and LCD display. It is specially designed for chemical, power station, electronic and It is developed to measure the pH of water in industries such as fermentation.
The pH transmitter is an industrial pH meter for continuous measurement. The preamplifier adopts high-quality high-impedance amplifier, and the pH electrode adopts three composite pH electrodes. The instrument has the characteristics of high measurement accuracy, fast response speed, small size, convenient installation and maintenance, etc.
The instrument adopts two-point calibration method, and the two-wire system uses 4~20mA output; the four-wire system uses 24V power supply and 4~20mA output. Because the meter transmits pH signal by current mode, it has strong anti-interference ability and long transmission distance.

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 about warranty ?
A: Warranty: 12 months, Lifetime maintenance
Q5. What are the applications of dissolved oxygen analyzers?
A: Sewage/Surface water monitoring/Aquaculture water bodies/Urban sewage treatment/Industrial wastewater treatment /Aquariums
