Mini-Diver
Cost-Effective
The Mini-Diver is based on an ingenious and proven concept and is acknowledged as the most reliable instrument for the autonomous measuring and recording of groundwater level and temperature.
Its internal memory of 24,000 measurements per parameter provides sufficient capacity to perform nearly one measurement every ten minutes for six months.
For each measurement, the Diver registers the date ａnd time, groundwater level, and temperature.
