The HBM-102B inline ORP transmitter is a compact and reliable solution for
industrial redox monitoring.
Designed for panel mounting (DIN96),
it integrates seamlessly into a wide range of process control systems —
ideal for ORP monitoring in water treatment, chemical processing,
and other demanding applications.
This redox transmitter for industrial use features
automatic stability control, simplifying calibration
while continuously assessing the condition of the ORP electrode.
Its finely adjustable high and low alarm outputs
ensure smooth system operation with precise reaction thresholds.
The HBM-102B supports various ORP electrodes,
including versions with replaceable measuring chips,
as well as immersion and flow-through sensors —
all tested in harsh industrial conditions.
For enhanced performance, the transmitter includes a dedicated cleaner output
that can directly control electrode cleaning systems
such as air jets, chemical rinsing, or mechanical brushes.
This reduces maintenance needs
and ensures long-term measurement stability.
Whether you're optimizing ORP in water treatment
or maintaining redox control in complex environments,
the HBM-102B delivers dependable performance
and intelligent automation in a compact format.
ORP (Oxidation-Reduction Potential) describes a substance’s tendency to either gain or lose electrons. It reflects how strongly a substance can act as an oxidizing agent (electron acceptor) or a reducing agent (electron donor). ORP is measured in millivolts (mV) and can have positive or negative values.
A positive ORP value indicates a strong oxidizing environment. Substances like chlorine or ozone, commonly used for disinfection, typically show high positive ORP readings. In contrast, negative ORP values point to strong reducing conditions, often associated with metals, antioxidants, or organic matter.
ORP transmitters play a key role in water treatment and quality monitoring. In drinking water systems, high ORP levels generally indicate effective disinfection, while lower values may suggest microbial activity or contamination risks.
In aquaculture, hydroponics, and agriculture, ORP measurement helps control water quality and maintain ideal conditions for plant growth and aquatic life.
Overall, ORP provides valuable insight into the chemical characteristics of a solution and its ability to drive or resist oxidation-reduction reactions. This makes it a critical parameter in process control, environmental monitoring, and industrial automation.
