Water Level Indicators
Humboldt water level indicators are designed for monitoring water levels in dams, reservoirs, wells, bores and underground cavities. These compact units include a handheld wire spool with an indicator module, a measuring cable and a probe to measure readings in feet and centimetres. The indicator module is further integrated with a power switch control (ON-OFF), test button, red light & horn for remote signalling and a sensitivity control to adjust to varying water conditions. Choose from an array of these water level indicators available in 150, 300 and 500 feet depth variants on Raptor Supplies.
