詳細信息 在線詢價

微型地下水自動監(jiān)測儀的直徑只有18mm,長度為90mm,是世界上體積最小小、精度的地下水水位水溫自動監(jiān)測儀。它是為孔徑很小的監(jiān)測孔專門設(shè)計的,其內(nèi)存可儲存48000組測量值,如以每10分鐘測量一次的頻率進行測量,可以連續(xù)監(jiān)測1年。Micro-Diver可以用固定頻率、變頻率進行監(jiān)測,還可以用于抽水試驗的水位水溫監(jiān)測。

Compact Size

Measuring only 88 mm (3.46") in length and 18 mm (0.71") in diameter, the Micro-Diver is the smallest Diver capable of accurately recording groundwater levels and temperature.

The Micro-Diver is specifically designed for monitoring wells or drive-points too small to accommodate larger dataloggers.

In addition to its compact size, the Micro-Diver’s memory capacity can store up to 48,000 measurements per parameter - almost one measurement every ten minutes for an entire year.

 

Features

Ø  Compact size: Ø 18 mm - length 88 mm

Ø  48,000 records of time stamp, pressure and temperature

Ø  30-Point Pressure Factory Calibration

Ø  Pre-programmed and user defined pumping tests

 

Benefits

Ø  Fits ¾ inch drive points and piezometers

Ø  Event based, averaging and pumping tests sample methods to conserve memory

Ø  Cost effective frequent, long-term measuring

Ø  Reliable and accurate data

Ø  No need to search through extraneous data

Ø  Fits any application

 

Applications

Ø  Groundwater monitoring projects

Ø  Direct push/Drive point piezometers

Ø  Pumping tests and slug tests

Ø  Estuary and wetlands monitoring

Ø  Groundwater monitoring network automation

Ø  Aquifer storage and recovery projects

Ø  Long term water level monitoring
