TDS Conductivity Meter with Probe, Measuring Range 2-2000 uS/CM Single freeboard area for excellent backwash

freeboard area for excellent backwash ratios

Solid state switching (SCR power control) with high limit

so usually there is a 1-2 week lead time on meters

there are thousands of Topaz Ultra PSA Oxygen Generators currently in use throughout the world
