Description
W650 Inline Online pH, EC, PPM, TDS & Temperature Meter
The W650 Inline offers the same advanced measurement capabilities and app functionality as the standard W650, but is specifically designed for direct installation into a pipeline. The inline electrodes feature a 3/4" threaded connection, allowing them to be screwed directly into a 3/4" tapping saddle. This enables accurate and continuous measurements directly in flowing water, without the need for a separate measurement chamber. Like the standard W650, the W650 Inline measures pH, EC, PPM, TDS, and temperature in real time and transmits all data via Wi-Fi to the Aqua Master Tools app. All inline electrodes are fully replaceable and designed to withstand water pressure up to 6 bar, making them suitable for pressurised pipelines and dosing systems.
Key features
• Continuous inline monitoring of pH, EC, PPM, TDS, and temperature
• Direct installation into pipelines using a 3/4" tapping saddle
• 3/4" threaded inline electrodes for easy mounting
• Real-time data available anywhere via Wi-Fi and app
• High and low alarms for all parameters
• Guided calibration and calibration reminders
• Unlimited inline devices can be managed in one app
• Compatible with other Aqua Master Tools devices
• Automatic temperature compensation
• Fully replaceable inline electrodes, rated up to 6 bar water pressure
App functionality
The W650 Inline uses the same Aqua Master Tools app and offers identical functionality:
• Live monitoring of all parameters
• Historical data viewing up to 1 year
• Alarm settings for pH, EC, PPM, TDS, and temperature
• Push notifications for alarms
• Guided calibration directly in the app
• Device naming and internal notes
• Central management of multiple inline and non-inline devices
Applications
The W650 Inline is ideal for applications such as:
• Inline dosing systems
• Irrigation and fertigation lines
• Water treatment and filtration systems
• Industrial process water monitoring
• Continuous flow applications where direct pipeline measurement is required
