Gravity Analog ORP Sensor – 5V BNC Probe

QAR 345.00/ unit

Description

The Gravity Analog ORP Sensor Meter for Arduino is designed to measure oxidation-reduction potential (ORP) in water quality monitoring applications. It provides a wide measuring range of ±2000mV with linear output characteristics for simplified calibration and integration. The module operates at 5V and interfaces directly with Arduino through an analog signal, requiring minimal external circuitry. Equipped with a BNC-connected ORP probe and onboard zero calibration button, it ensures stable and reliable measurements. Ideal for water treatment systems, sanitation monitoring, laboratory testing, and environmental analysis. Attention： The bottle cap of the probe contains protective liquid (3.3mol/L KCL). Even if the bottle cap is screwed tightly, some protective liquid may still leak around the bottle cap, forming white crystals. But as long as there is still protective liquid in the bottle cap, it will not affect the life and accuracy of the probe. So please use it with confidence. It is recommended that the white crystals be poured back into the protective liquid in the bottle cap.
