VanEssen Mini-Diver Laboratory Water Magnetic switches for zeroing and

Magnetic switches for zeroing and calibrating and an infrared communications link eliminate outside pin connections and associated corrosion problems

a stainless steel sensor mounting bracket and clamps

without the problems of other devices

so both samples and the well are protected from disturbance or the danger of cross-well contamination

all models having a voice notes capability

VanEssen Mini-Diver Laboratory Water Magnetic switches for zeroing andThe 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
