Repair No
Calibration No
Free Support No

Overview

The SR50 measured elapsed time between emission and return of an ultrasonic pulse. An independent air temperature measurement was required. The SR50 output SDI-12, pulse train, or serial ASCII. Output options were configured with internal jumpers.

The "-L" on a product model indicates that the cable length is specified at the time of order.
