Gecko Low Water Sensor, model 1102 Chrome (SKU 9920-400775), is a precision water-level detector designed to protect your aquatic systems from dry-running pumps and compromised filtration. Built for reliability in damp environments, its chrome-plated housing resists corrosion and blends with modern gear—from reef tanks to hydroponic reservoirs.
This sensor isn't just an isolated device. It’s engineered to work within the Aquatic Industries lineup, pairing with the Hesso Passport Ensemble and HydroBaths Sensatron networks to deliver centralized monitoring, alerts, and automated responses. A discreet, robust chrome body keeps its appearance and performance intact over years of use.
Place the sensor at the reservoir’s lowest point to ensure early notification of water loss. Pair it with your control system to automatically pause pumps or trigger alarms when the threshold is reached. For best results, test the threshold and alerts monthly, and keep wiring dry and connections secure to maintain long-term reliability.
Ideal for hobbyists and professionals who demand dependable water-level monitoring in compact spaces. If you operate reef aquariums, planted tanks, hydroponic systems, or HydroBath maintenance setups, the Gecko 1102 Chrome delivers precise feedback and a polished look that matches premium equipment.
