MICRO-DIVER. Launched May 2006. The smallest Diver in the range, just 18mm in diameter and small enough to fit in standard 19mm internal diameter monitoring wells.

CERA-DIVER - Newly launched, May 2006. The same size as the Mini-Diver, but constructed entirely in ceramic to prevent any possibility of corrosion in aggressive groundwater.

MINI-DIVER - The original diver, now enhanced with new electronics and now even shorter in length. The Diver is available in various measuring ranges.

CTD DIVER - Measures groundwater level, temperature and conductivity.  It measures 22mmOD by 183mm long. Ceramic construction.

The standard warranty for all Divers is 3 years.

POCKET-DIVER, pictured above. To facilitate the field use of Divers with the aid of a Pocket-PC or PDA, Van Essen has also introduced the Pocket-Diver software package. The software permits Divers to be programmed and/or readout in the field. Pocket-Diver comes in two versions: Pocket-Diver Reader enables the field readout of measurement data, whilst Pocket-Diver Manager also offers the field programming option. For this purpose the Divers are connected to a readout unit or via an interface cable to the Diver Read Cable.
