RIKA SENSOR / DATA CENTER LIQUID COOLING
Conductivity, pH, ORP and turbidity monitoring for CDU and cold plate cooling loops.
FOUR PARAMETERS TO FOLLOW
Select dedicated sensors for the measurements your cooling loop needs.
SENSOR COLLECTION
The RK500-LC series provides four dedicated measurements for liquid cooling water quality monitoring. Choose individual sensors or combine them to follow coolant conditions over time.
RK500-13LC
Track changes in coolant ionic condition. Select Type A or Type B according to the required conductivity range.
Resolution: 1 µS/cm. Response time: 1 second. Type B can be customized to 0-20000 µS/cm. FS = full scale.
RK500-12LC
Follow coolant acidity and alkalinity. Use pH trends to review changes against the requirements of your coolant and equipment.
| Range | 0-14 pH |
|---|---|
| Accuracy | ±0.1 pHAt 25°C |
| Resolution | 0.01 pH |
| Response time | 10 seconds98% response in flowing liquid |
Low-impedance sensitive glass membrane, automatic temperature compensation and internal signal isolation. Main materials: 316L stainless steel + titanium alloy.
RK500-06LC
Track coolant oxidation-reduction potential. ORP adds information about oxidizing and reducing conditions within the cooling circuit.
| Range | -1500 to +1500 mV |
|---|---|
| Accuracy | ±1 mV |
| Resolution | 0.1 mV |
| Response time | 14 seconds98% response in flowing liquid |
Platinum ring electrode and internal signal isolation. Main materials: 316L stainless steel + titanium alloy.
RK500-07LC
Follow coolant cleanliness trends and changes in suspended impurities. Establish a baseline and investigate sustained movement.
| Ranges | 0-10 NTU or 0-100 NTU |
|---|---|
| Accuracy | ±2% of reading or ±0.1 NTUWhichever is greater |
| Resolution | 0.1 NTU |
| Response time | 1 second |
90° nephelometric method with a sapphire measurement window and 316L stainless steel construction. Turbidity alone does not identify contaminant type or particle size.
SHARED TECHNICAL DATA
Based on the four product specifications, V5.2.0. Confirm coolant composition, concentration, material compatibility and process connection before ordering. Measurement ranges describe sensor capability; set alarm limits according to the coolant supplier and equipment requirements.
SYSTEM INTEGRATION
01 / MEASURE
Place the selected EC, pH, ORP and turbidity sensors at representative points in the CDU or cooling loop.
02 / COLLECT
Connect sensor outputs to compatible controller inputs or data collectors. Review signal mapping and communication requirements for the project.
03 / REVIEW
Use your monitoring platform to record trends, display readings and manage alarms for the configured measurements.
Data collection, platform connectivity, trend storage and alarm functions depend on the selected controller or monitoring system. Confirm the required integration architecture with RIKA SENSOR.

LIQUID COOLING PROJECTS
Project examples from RIKA SENSOR. Deployment scale and integration arrangements are specific to each project.
View All Water Quality Monitoring ProjectsSELECTION & INSTALLATION
Share the coolant type and concentration, normal measurement range, temperature and pressure. Select the EC variant and turbidity range for the expected conditions.
A bypass section helps with maintenance. Prefer vertical upward flow or a suitable horizontal location. Avoid turbulence, trapped gas, sediment and positions downstream of pressure reduction.
Keep pH and ORP electrodes at least 15° from horizontal. For turbidity in stainless steel pipes, keep the probe at least 30 mm from the wall and align the measuring holes parallel to flow.
Leave at least 70 mm of outlet clearance for an M16 connector. Follow the model-specific care instructions; pH and ORP electrodes require KCl soaking when not in use.
COMMON QUESTIONS
The listed media are deionized water, PG25 and EG25. Share your coolant formulation and concentration so the sensing method and wetted-material compatibility can be reviewed before ordering.
Select a measurement range for the conditions you expect to measure. Define alarm thresholds from the requirements of your coolant, equipment and operating process, using a stable baseline and appropriate trend review.
EC follows ionic condition, pH follows acidity and alkalinity, ORP follows oxidation-reduction conditions, and turbidity follows cleanliness trends. Review them together with operating conditions and inspection findings to decide when further investigation is needed.
