DR-1050
Depth Recorder

The DR-1050 is a small (38mm diameter, 220mm long), self-contained, submersible depth or pressure recorder. Pressure measurements are made to 24-bit resolution. The DR-1050 is calibrated to an accuracy of ±0.05 % full scale using NIST traceable standards.

Each unit employs an absolute pressure gauge, with ranges selectable from 10 dBars (10 metres of water) to 6.600 dBar making the unit suitable for a wide range of applications from borehole testing and groundwater monitoring to deep ocean. For groundwater measurement, a barometric reference may be used to record the atmospheric pressure over the local area. An optional underwater serial output permits triggering of sampling apparatus at preset depths.
