RK500-12 (Liquid cooling) pH Sensor-M16 connector
PRODUCT DESCRIPTION
The RK500-12 liquid-cooled pH sensor is tailored for precise monitoring of liquid cooling systems, addressing the critical impact of cooling liquid cleanliness on system stability. As the stable operation of liquid cooling systems hinges on the purity of the cooling liquid—where contaminants like particulate matter, corrosion products, and microbial impurities can reduce heat dissipation efficiency, clog pipelines, corrode components, and even trigger system failures or downtime accidents—this sensor serves as a key monitoring tool. It utilizes advanced glass electrode technology paired with a high-precision signal processing chip to accurately measure pH values, sensitively capturing subtle changes in the acidity or alkalinity of the cooling liquid. Whether operating in acidic or alkaline environments, it delivers accurate and stable monitoring data, laying a reliable foundation for evaluating the operating status of liquid cooling systems and preventing hazards caused by imbalanced pH levels.

Installation & Fixed
● Install sensor on bypass pipe section for ease of maintenance.
● Install sensor on bypass pipe section for ease of maintenance.
●Choose a location with stable fluid flow and no obvious turbulence to ensure
measurement accuracy and stability.
● Optimal position: vertical upward flow (Pos. ④). If site conditions are limited,
horizontal piping (Pos. ②) is also acceptable.
● Do not install in high-point gas traps (Pos. ⑤) or low-point sediment zones (Pos.
③), as bubbles or deposits may affect accuracy or damage the sensor.
● Do not install on vertical downward flow (Pos. ①) to prevent degassing and
measurement drift.
●Do not install downstream of pressure-reducing sections to avoid degassing
from sudden pressure drop.
●Avoid bubble generation near the measurement window in all installations.
●With M16 connector, keep ≥70 mm outlet clearance to prevent cable damage from over-bending.●When installing the pH sensor, keep it at least 15° from the horizontal line (Fig. ⑥).
