The 25 key keypad puts the most used functions at your finger tips. For those of you who still wish to hear your meter “clicks”, the internal speaker will let you hear them without a headset, and can sound a tone when you press a key or when the AquaCalc displays a message.

The user interface has been designed to make taking stream discharge measurements easier. With the larger display it is possible to see up to three observations in a vertical on the same screen, plus measurement settings and messages. Plus a continuous display of estimated instantaneous velocity so that you can see what the stream is doing before you begin your “official” observation.

The menu system, combined with three “soft-keys”, whose functions can be changed as needed, give the user easy access to the AquaCalc’s capabilities.

Hardware design includes a rugged case with full gaskets designed to withstand directed hard spray (international standard for water resistant of IP65), scratch resistant display lens, integrated USB port with protective cap, and a custom designed mounting bracket.

The AquaCalc’s measurements can be downloaded to a computer using the included AquaCalc DataLink 3 and displayed in graphs and reports. The AquaCalc Excel Analyzer file will allow you to import and edit measurements after they have been downloaded to you computer.
