Pressuredaq was designed to take advantage of available technology to simplify the recording of pressure data for pressure tests. The system is well suited to replace conventional circular and strip recorders that are currently being used in pressure testing applications.
The system is easily portable, weathertight, and simple to use. Pressuredaq has a self-explanatory front page: simply set your transducer range for each channel, select the data recording rate, then click “Start Recording”. It’s that simple. With the included Datagrapher software, viewing your data as a graph is a simple process, too. Just click “Get Data” and it’s automatically loaded and scaled.
