850 Precision Altimeter
The Imagenex Model 850 Precision Altimeter accurately measures the range to the bottom, surface, obstacles or objects. It is a completely self-contained unit, less than 2” in diameter and approximately 7” long, making it ideal to use for many applications. With your choice of 500 kHz or 200 kHz, it requires only power and an RS-232 or RS-485 serial interface to an external device.
