Best Price for Total Dissolved Solids Tester Meter - CS1778D Digital pH Sensor – Chunye Detail:
•Using large-area low-resistance sensitive film bulb ≤30MΩ (at 25℃), suitable for usage in ultra-pure water
•Using gel electrolyte and solid electrolyte salt bridge. Pool electrode is composed of two different colloidal electrolytes. This unique technology ensures longer electrode life and reliable stability
•It can be equipped with PT100, PT1000, 2.252K, 10K and other thermistors for temperature compensation
•It adopts advanced solid dielectric and large area PTFE liquid junction. It is not easy to be blocked and 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 and prevents the generation of interfering bubbles in the internal buffer, making the measurement more reliable.
•The electrode adopts high-quality low-noise cables, which can make the signal output length longer than 20 meters without interference. Pure water composite electrodes are widely used in circulating water, pure water, RO water and other occasions
