Data loggers GSR 120NT and GSR 120NTG

The GSR 120 logger family consists of two data loggers: type GSR 120NT, which measures and registers level (or pressure) and temperature and type GSR 120NTG, which in addition to level (pressure) and temperature measurements records also the conductivity of the media (water). They are characterized by a compact immersion housing made from stainless steel, battery or external power supply, communication connection RS 485 and the possibility of connecting a GSM modem for wireless data transmission.
Application: monitoring of groundwater, surface rivers and lakes, wells, ...
