- 6-in-1 WiFi pH/EC/TDS/SALT/SG/Temp controller and monitor: simultaneously measures and displays pH and one selectable parameter from EC, TDS, SALT, SG, or TEMP. Switch modes to view the data you need. - Includes 2 BNC electrodes (one for pH, one for EC/TDS/SALT/SG), plus 1 temperature probe and 1 output power socket. Both electrodes are detachable and easily replaceable. - LCD with backlight for clear readings and the ability to monitor multiple parameters at a glance, even in low light conditions. - WiFi connectivity and a companion app to view current and historical data on your smartphone, with alerts for abnormally high or low values and data logs. - Practical use scenarios: - Hydroponics and aquaponics systems: keep pH and conductivity (EC/TDS) within optimal range to support plant growth and fish health; receive real-time alerts to prevent crop stress. - Pool, spa, and drinking water maintenance: monitor pH alongside a second parameter (EC/TDS/SALT/SG) and temperature to ensure safe and comfortable water conditions; remote monitoring helps with routine checks. - Small laboratories or beverage/food processing: track water quality during experiments or production, with easy sensor replacement and remote logs for quality control. - Benefits and performance: 1 unit handles multiple critical water quality parameters, reducing equipment clutter; detachable, replaceable sensors simplify maintenance; built-in display for local readings plus remote data access and alarms for proactive management.
