The AquaMaster C800 Pro and AquaMaster C800 Inline Pro are professional-grade EC (electrical conductivity) and temperature meters designed for precise monitoring of nutrient solution strength in hydroponic, coco, soil and commercial growing systems. Available as a handheld portable meter or a continuous inline monitor, the C800 range delivers reliable, accurate EC readings to help growers optimise feeding schedules and maximise plant performance.

Both models are ideal for hydroponics, greenhouse cultivation, fertigation systems, reservoirs, irrigation lines and commercial agriculture. Whether you need a portable EC tester for spot checks or a permanent inline EC monitor for real-time tracking, the AquaMaster C800 range offers a dependable solution.

The system can be operated via the intuitive color touchscreen, which displays real-time values, alarm status, and historical data. For additional functionality, the C800 connects to the free Aqua Master Tools app (iOS/Android) via WiFi, giving you:

• The ability to store nutrient dosing schedules in the cloud and reuse them later
• Instant alarm notifications directly to your smartphone
• Access to real-time and historical graphs
• Remote adjustment of all dosing settings, set points, alarms, and calibration reminders
• Remote management of multiple devices from one app

Both the controller and the app allow you to view up to 12 months of historical measurements and alarms, giving you full insight and control over your system at all times.

• C800 Inline Pro – Fixed inline EC monitor for continuous measurement within irrigation systems and recirculating setups.

C800 Pro – Portable EC & Temperature Meter

The C800 Pro is a robust handheld digital EC meter designed for quick and accurate testing of nutrient solutions. Its ergonomic housing and clear digital display make it perfect for growers who regularly test reservoirs, mixing tanks and runoff.

Key Features

• Measures EC (mS/cm) and temperature
• High-accuracy digital conductivity sensor
• Easy calibration for long-term precision
• Clear, easy-to-read display
• Water-resistant durable housing
• Suitable for hydroponic nutrient solutions and irrigation water

Maintaining correct EC levels is essential for preventing overfeeding or underfeeding. The C800 Pro provides dependable readings so you can fine-tune nutrient strength for maximum yield and healthy root development.

C800 Inline Pro – Continuous Inline EC Monitor

The C800 Inline Pro is designed for growers who require constant EC monitoring within their irrigation or recirculating systems. Installed directly into pipework, it provides continuous real-time conductivity and temperature readings without the need for manual testing.

Key Features

• Continuous inline EC monitoring
• Measures EC and temperature in real time
• Ideal for recirculating hydroponic systems
• Durable industrial-grade probe
• Suitable for professional and commercial grow operations

This model is particularly valuable in large-scale grow rooms, greenhouses and commercial fertigation systems where stable nutrient strength is critical to crop consistency.

Why Monitor EC & Temperature?

Electrical conductivity (EC) indicates the concentration of dissolved fertiliser salts in your nutrient solution. Keeping EC within the correct range prevents nutrient burn, deficiencies and poor plant development. Integrated temperature monitoring ensures nutrient solution stability and supports healthy root-zone conditions.

The AquaMaster C800 range provides the accuracy and reliability required for serious growers.

Combining with Automated Peristaltic Dosers

This controller really comes into its own when combined with the modular dosing pumps. Combine it with a single pH doser to control pH fluctuations, and up to 5 nutrient dosers to supply the nutrient of your choice (sp up to 6 pumps in total). You don't need to aquire a complete set of pumps from the offset, it's possible to purchase just the pH or nutrient dosers and add others on later.
