Remote Dissolved Oxygen Controller (Mains-Powered)

Description

Designed and built in the UK, the Intuifish Remote Dissolved Oxygen Controller provides continuous dissolved oxygen and water temperature monitoring, helping fisheries identify potential problems before they impact fish welfare.

This monitoring-only configuration is supplied with an IP67-rated mains power supply and continuously uploads readings to the Intuifish platform, allowing you to view live conditions, analyse historical trends, and receive instant alerts when dissolved oxygen levels fall below your chosen thresholds.

Ideal for fisheries that already have existing aeration systems or simply require monitoring and alerting, the system delivers professional-grade water quality monitoring without ongoing subscription fees.

Currently deployed at 25 venues and responsible for over 76303 dissolved oxygen readings.

• Continuous Remote Monitoring – 24/7 dissolved oxygen and water temperature monitoring with live data available from anywhere.
• Instant Alerts — Receive notifications when dissolved oxygen levels fall outside your configured limits.
• No Subscription Fees — Includes lifetime access to the Intuifish monitoring platform at no additional cost.
• Online Dashboard & Data History — Review historical readings, trends, and environmental conditions from your smartphone, tablet, or PC.
• Simple Installation — Supplied with an IP67-rated mains power supply for straightforward deployment.
• Built for Fisheries — Developed using real-world fishery management experience and designed specifically for aquatic environments.
• Aeration Control — A low-voltage on-board signal relay opens up connection possibilities to control a wide array of aeration equipment via SMS text messaging, low dissolved oxygen thresholds and timers. 
• Reliable SMS-Based Control — While many monitoring systems rely on complex apps and internet-connected interfaces, Intuifish uses proven SMS technology for alerts and system configuration. This provides a simple, reliable way to receive notifications and adjust settings remotely without requiring dedicated apps, software updates, or constant internet connectivity. The result is a system that remains easy to use, dependable, and accessible from virtually any mobile phone.

Important Notice(s):

1) This listing is for; 1x Remote Dissolved Oxygen Controller supplied with a 15M Probe Cable with inline-float and a 30CM IP67 13A Mains to 12V Power Supply. Other configurations are available in our shop if you need a solar-powered system, or a mains system which includes the components required for aeration switching. However, all Intuifish Remote Dissolved Oxygen Controllers use the same core hardware and software platform. Whether supplied as a monitoring-only unit, with aeration control, or as a solar-powered system, every configuration can be upgraded or reconfigured as your requirements change. This allows fisheries to start with the solution they need today while retaining the flexibility to add aeration control or move between mains and solar power in the future without replacing the entire system.

2) Our preference is to receive your chosen SIM card to our address prior to us shipping your order, in order we can fully test with your chosen network provider and ensure your equipment is fully ‘plug & play’ on arrival to you. Lots of our customers user either Lebara or Spusu but all UK networks can be used with our equipment.
