III. BENEFITS

1. Instant Measurement: Instead of investing in an expensive fixed monitoring system, users can quickly check water quality parameters at any time within seconds.

2. Digital Data Management: Store measurement data and view charts directly on a smartphone, eliminating manual record-keeping, reducing errors, and making it easier to compare readings over time.

3. Cost Efficiency: A single meter can be used with different types of sensor probes, helping optimize equipment investment costs.

IV. OPERATING PRINCIPLE

1. The device measures pH, dissolved oxygen (DO), and temperature in liquids at one-second intervals and displays the readings directly on its LCD screen. When measured values exceed the configured thresholds, the device activates an audible alarm.

2. The device connects to the Internet via Wi-Fi and transmits measurement data to a mobile application. Users can remotely monitor and configure the device through the Navis app, available on the Apple App Store and Google Play, anytime and anywhere with an Internet connection.

3. Sensor Readings / Main Screen Display: These are real-time values received from the sensors, including dissolved oxygen (DO), pH, and temperature measurements.

4. User-Defined Alarm Thresholds: These are DO or pH values configured by the user for comparison with actual sensor readings. Based on this comparison, the device determines whether to activate or deactivate the audible alarm and sends notifications to the user's mobile phone.

Operating Modes

The device supports two operating modes: CONTROL and MONITOR.

1. CONTROL Mode: The output control terminals are enabled and operate according to the configured settings.

2. MONITOR Mode: The output control terminals are disabled. Only the sensors and external alarm buzzer remain operational.

V. ERRORS, WARNINGS, AND TROUBLESHOOTING

When an error or warning occurs, the corresponding error or warning message appears on the screen. At the same time, the audible alarm is activated, and the warning indicator light flashes.

Users must identify and resolve the error to ensure that the device can continue operating properly.
