Cera Diver

Cera Diver

Overview

Hydrolab Quanta Meter

The ceramic Cera Diver is designed specifically for monitoring groundwater in potentially corrosive conditions, such as brackish water and seawater. Robust and durable, the Cera Diver is a perfect for mining areas where the groundwater and surface water may have high concentrations of acidity and metals due to dewatering.

Measuring 90mm in length and 22mm in diameter, this highly reliable and compact Diver registers groundwater levels with an accuracy of 0.05% (Full Scale). It is equipped with a memory capable of storing 48,000 measurements per parameter. This is sufficient enough to perform one measurement every ten minutes for an entire year.

Features & Benefits

  • Records groundwater level and temperature.
  • Small ranges available for increased accuracy.
  • robust corrosion resistant housing.
  • No need to continually replace batteries, Internal battery power supply (8-10 years depending on use).
  • hermetically sealed in stainless steel housing.
  • Memory (non-volatile) for max. 48,000 measurements.
  • Various models available: 10m, 20m, 50m, 100m.

Applications

  • Pumping and slug tests.
  • Dewatering applications, drainage basins and recharge areas.
  • Stream gauging, lake levels and reservoirs.
  • Harbour and tidal fluctuation monitoring.
  • Wetlands and stormwater run-off monitoring.
  • Long term water level monitoring in narrow monitoring wells (19mm).
