1. The polymer filling makes the reference junction potential very stable.
2. The diffusion potential is very stable; large-area diaphragm surrounds the glass diaphragm bubbles,
so that the distance from the reference diaphragm to the glass diaphragm is near and constant; the ions
diffused from diaphragm and the glass electrode quickly form a complete measurement circuit to respond
quickly, so that the diffusion potential is not easy to be affected by the outside flow rate and is thus very stable!
3. As the diaphragm adopts the polymer filling and there is small and stable amount of overflowing electrolyte,
it shall not pollute the measured pure water. Therefore, the above-mentioned features of the composite
electrode make it ideal for measuring PH value of high-purity water!
| Measuring range | 0-14pH |
| Temperature range | 0-50ºC |
| Accuracy | ≤ 0.02PH |
| Response time | ≤ l0sec |
| Slope | ≥96% |
| Zero point potential | E0=7PH±0.3 |
| Internal resistance | ≤ 50MΩ (25ºC) |
| Drift | ≤ 0.03PH/24h no accumulation |
| Installation | Rotary locking type and tail 3/4 thread (Rotate the electrode for 1/4 circle to insert it into or take it out of the process.) |
| Application | It is widely used for measurement of all kinds of pure water and high-purity water in such places as thermal power plants (with the flow cell). |

Shanghai BOQU Instrument Co.,Ltd was established in 2007, and located in Kangqiao Town Pudong New
Area Shanghai. It is the professional manufacturer of electrochemical instrumentation and electrode combine
with the R&D, production and sales. The main products include pH, ORP, conductivity, ion concentration,
dissolved oxygen, turbidity, alkali acid concentration and electrode etc.
BOQU was found since 2007, now has more 100 staff and engineers, instruments has be exported to
over 100 countires.,Now BOQU has been named as High-Tech Enterprice by goverment,ISO,CE, SGS is
our common certicates. the core technology of electrode ,controller and 50+ software property is our
based. all instruments has been recognized by National Metrology Bureau.there is many small factories
in China, you should be carefully if they provide you very low price. this is tips for you in free.
pp bag, paper box. sponge, seaworthy box, Wooden box;
Mainly product: pH Sensor etc
The BOQU Instrument is a young, energetic, and professional team. We will continue to focus on R&D and
manufacturing of high-end water quality monitoring instruments and sensors. we keep to create benefits for our
customers, We work hard for the material and spiritual aspects of all employees and contribute to the progress
and development of humanity. forever to guard the earth's water quality.
