ORP Sensor Manufacturer and Supplier in Ahmedabad
Aranka Instruments LLP is a reputed ORP Sensor Manufacturer and Supplier in Ahmedabad, Gujarat, India, offering high-quality sensors designed to accurately measure the oxidation-reduction potential (ORP) of liquids in industrial, laboratory, and environmental applications. Our sensors are built for durability, stability, and precision, ensuring consistent performance even in harsh process conditions.
An ORP (Oxidation-Reduction Potential) sensor measures the ability of a solution to either gain or lose electrons, which indicates its oxidizing or reducing strength. It operates by detecting the voltage difference between a noble metal electrode (typically platinum or gold) and a reference electrode, representing the electron activity within the solution. This measurement helps determine the chemical balance, water quality, and disinfection effectiveness in various systems.
Aranka’s ORP Sensors are widely used in water treatment plants, swimming pools, wastewater monitoring, chemical processing, and electroplating industries. With reliable construction and easy calibration, they integrate seamlessly with controllers, transmitters, and PLC systems for automated monitoring and control.

Frequently Asked Questions (FAQ)
What is an ORP sensor used for?
An ORP sensor measures the oxidation or reduction potential of a liquid, indicating how strongly it can gain or lose electrons. It is used to monitor water quality, disinfection, and chemical balance in various processes.
How does an ORP sensor work?
The sensor measures the voltage between a noble metal (platinum or gold) electrode and a reference electrode. This voltage reflects the electron activity and helps determine whether the solution is oxidizing or reducing in nature.
What is the typical ORP range?
Most ORP readings range between -1000 mV to +1000 mV. Positive values indicate oxidation potential, while negative values indicate reduction potential.
Where are ORP sensors commonly used?
ORP sensors are widely used in wastewater treatment plants, swimming pools, cooling towers, electroplating units, and chemical industries for monitoring redox reactions and water quality.
How should an ORP sensor be maintained?
Regular cleaning with distilled water, periodic calibration using ORP standard solutions, and proper storage when not in use help ensure accurate and long-lasting performance.
Do you offer customized ORP sensors?
Yes, as a leading ORP Sensor Manufacturer in Ahmedabad, Aranka Instruments provides custom designs based on process media, temperature range, and installation type.
