2021 New Style Conductivity TDS Sensor with RS485 4-20mA - CS1540 pH Sensor – Chunye Detail:
•CS1540 pH electrode adopts the most advanced solid dielectric in the world and large-area PTFE liquid junction. Not easy to block, easy to maintain.
•The long-distance reference diffusion path greatly prolongs the service life of the electrode in harsh environments. The newly designed glass bulb increases the bulb area, prevents the generation of interfering bubbles in the internal buffer, and makes the measurement more reliable.
•Adopt Titanium alloy shell, upper and lower PG13.5 pipe thread, easy to install, no need for sheath, and low installation cost. The electrode is integrated with pH, reference, solution grounding.
•The electrode adopts high-quality low-noise cable, which can make the signal output longer than 20 meters without interference.
•The electrode is made of ultra-bottom impedance-sensitive glass film, and it also has the characteristics of fast response, accurate measurement, good stability, and not easy to hydrolyze in the case of low conductivity and high purity water.
