Gravity: Analog ORP Sensor PRO

SKU: SEN0464

Gravity: Analog ORP Sensor PRO is an upgraded industrial ORP sensor. It uses a platinum indicator electrode and silver-silver chloride reference electrode, enabling 24-hour online ORP monitoring with enhanced durability. The new signal converter adds a stable voltage reference, so readings aren’t affected by supply voltage fluctuations. Accessories include screws, copper columns, and waterproof connectors for easy ORP monitoring system setup.
