產(chǎn)品介紹
微型地下水自動(dòng)監(jiān)測(cè)儀的直徑只有18mm,長(zhǎng)度為90mm，是體積小、精度高的地下水水位水溫自動(dòng)監(jiān)測(cè)儀。它是為孔徑很小的監(jiān)測(cè)孔專(zhuān)門(mén)設(shè)計(jì)的，其內(nèi)存可儲(chǔ)存48000組測(cè)量值，如以每10分鐘測(cè)量一次的頻率進(jìn)行測(cè)量，可以連續(xù)監(jiān)測(cè)1年。Micro-Diver可以用固定頻率、變頻率進(jìn)行監(jiān)測(cè)，還可以用于抽水試驗(yàn)的水位水溫監(jiān)測(cè)。

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.
