RIKA SENSOR / DATA CENTER LIQUID COOLING
Online ORP monitoring for liquid cooling.
OVERVIEW
The RK500-06LC measures coolant ORP in liquid cooling systems, including data centers. It uses a platinum ring electrode and supports continuous online monitoring.
ORP stands for oxidation-reduction potential. Measured in millivolts (mV), it reflects how oxidizing or reducing the coolant is. Excessive oxidation can accelerate corrosion of metal components in the cooling system.
APPLICATION
Follow ORP changes as coolant circulates. Review readings and trends against the operating requirements for your coolant and equipment.
The conceptual diagram shows an ORP sensor on a return-line bypass, with a signal connection to a controller. Use ORP readings alongside other relevant coolant measurements and maintenance observations when deciding what action to take.
PRODUCT FEATURES
Designed for online ORP measurement in oxidizing and reducing environments. Internal signal isolation helps reduce electrical interference.
Measures from -1500 to +1500 mV, with a specified accuracy of ±1 mV and a resolution of 0.1 mV. The specified response time is 14 seconds to 98% response in flowing liquid.
Simultaneous 4-20 mA and RS485 outputs connect to compatible monitoring equipment. The sensor operates on 7-30 VDC and consumes less than 0.2 W.

Specification V5.2.0. Confirm the coolant type, concentration and material compatibility before ordering. The electrode requires KCl soaking when not in use; see the care instructions below.
INSTALLATION
Install on a bypass pipe for easier maintenance. Choose a location with steady flow and no obvious turbulence. Vertical upward flow is preferred; a suitable horizontal pipe is also acceptable.
Keep the ORP sensor at least 15° from the horizontal line.
Avoid high-point gas traps, low-point sediment zones, vertical downward flow and positions downstream of pressure-reducing sections. Bubbles and deposits can affect readings.
For the M16 connector, leave at least 70 mm of cable outlet clearance to prevent excessive bending.
ELECTRODE CARE
Remove the protective cap in front of the electrode before placing the sensor into service.
Soak the electrode in 3 mol/L KCl solution or saturated KCl solution.
Do not store it immersed in distilled water, deionized water or tap water with very low ion content.
Follow the cleaning procedure in the product specification for the type of contamination present.
The specification recommends cleaning with tap water every 6 months, according to the working environment.
SPECIFY YOUR RK500-06LC
Share your coolant type and concentration, required ORP range, operating temperature and pressure, process connection, and controller input requirements. Include your preferred cable connection and length, if known.
Our team can help review the process connection, cable option and sensor configuration for your cooling loop.
