Description

In the ever-increasing need and awareness for health and safety, water has become a focus point for proper disinfection treatment as aftereffects of industrialization can become a danger for contamination of water via direct contact. Water is a critical control point of contact where proper treatment can greatly reduce these microbes, thereby reducing the chances of illness and pollution.

While traditional ORP meters are hard to get or use, this Analog ORP Meter is a highly compact ORP monitoring system that fits into your Arduino. This design configuration allows the user to accurately monitor ORP without having to add any additional circuitry or components to your design. Communication with the Analog ORP Meter is done using only simple wiring and programming.

Applications:

Water Quality Testing
Aquaculture
Marine Science
Hydroponic Gardening
General Chemistry

Features:

Analog ORP Meter can be done using only simple wiring
Zero calibration button
Power Indicator LED
ORP Probe with BNC Connector

Package Includes:

1 x ORP probe (BNC connector)

1 x ORP probe circuit board

1 x Analog cable
