Principle
In PH measurement, the used electrode is also known as the primary battery. The primary battery
is a system, whose role is to transfer chemical energy into electrical energy. The voltage of the
battery is called the electromotive force (EMF). This electromotive force (EMF) is composed of
two half-batteries. One half-battery is called the measuring electrode, and its potential is related
to the specific ion activity; the other half-battery is the reference battery, often called the reference
electrode, which is generally interlinked with the measurement solution, and connected to the
measuring instrument.

Features of PH Electrode:
1.It adopts the world-class solid dielectric and a large area of PCE liquid for junction,difficult to block
and easy maintenance
2.Long-distance reference diffusion channel greatly extends the service life of
electrodes in the harsh environment
3. A new design of glass bulb increases the bulb area, prevent bubble formation
interference within the buffer, makes the measurement more reliable.
4.It adopts PPS/PC casing and the upper and lower 3/4NPT pipe thread, so it is easy for installation
and there is no need of the jacket, thus saving the installation cost.
5.The electrode adopts the high-quality low-noise cable, which makes the signal output length less
than 20 meters free of interference.
6.There is no need for additional dielectric and there is a little amount of maintenance.
7.High measurement accuracy, fast echoing and good repeatability.
8.Reference electrode with silver ions Ag/AgCL
9.Proper operation shall make service life longer.
10.It can be installed in the reaction tank or pipe laterally or vertically.
11.The electrode can be replaced by a similar electrode made by any other country.

Q2: How do you guarantee the quality?
A: One year's guarantee from date on B/L. Normally. If it's quality problem, we promise to return goods or funds.
Q3: Is OEM available?
A: Yes, all goods can be custom made by your requirements, including packing, LOGO print, etc.
Q4: Can we buy 1 pc for sample testing?
A: Yes, we are glad to send 1pc for quality testing if we have stock of the model you required.
Q5: How to deliver the goods for trial order or small order?
A : For small order, we prefer to choose international express, such as DHL, TNT, EMS , FedEx
which are faster and more convenient for customer. Also, we cooperate with an express agent that can give us a big discount for express fee which is much lower than that quoted by official. For the goods with detachable battery, the express fee can be lower down if the goods is sent out without battery.
