The Vented Logger is a reliable and cost-effective solution for long-term monitoring of groundwater levels and temperatures in wells, wells and open waters. The Heron Vented Logger is also ideal for short-term pump and shock test applications or for wetland and tidal studies.
The direct read cable with built-in vent tube allows the logger to automatically compensate for barometric pressure changes. The sintered Teflon air filter in the direct read head prevents moisture from accumulating in the breather hose. The unique design of the filter does not need to be replaced.
