Rika Sensor is a weather sensor manufacturer and environmental monitoring solution provider with 10+ years of industry experience.
PRODUCT DESCRIPTION
The RK500-15 is a high-precision ammonia nitrogen sensor designed for rapid, reliable measurement of ammonium ions (NH₄⁺) in aqueous environments. Utilizing a PVC-membrane ammonium ion electrode with integrated temperature compensation, this sensor delivers fast, stable readings while minimizing maintenance requirements. Its unique design features a slow-release internal reference solution through a microporous salt bridge, significantly extending electrode lifespan compared to conventional industrial electrodes.
Key Features
•Advanced Sensing Technology: PVC-membrane electrode ensures accurate NH₄⁺ detection in water.
•Magnetic Isolation: Enhanced anti-interference capability for stable performance in complex environments.
•All-in-One Design: No external modules required, simplifying installation and operation.
•Dual Output Compatibility: Supports both 4-20mA analog and RS485 digital interfaces for flexible system integration.
•Versatile Installation: Immersion or pipeline mounting options; includes a 1-meter installation bracket with NPT3/4 threaded connector.
•Longevity: Extended electrode life due to slow-release internal reference fluid.
