The Ralston FieldLab Mobile App turns your Bluetooth-enabled Ralston Field Gauges into a complete field pressure and temperature logging solution.
Available free for iOS and Android.
Compatible with Ralston Gauges with Bluetooth.


Monitor multiple measurements in one place instead of tracking readings separately in the field.

Use it for hydrostatic testing, water cross-connection testing, leak testing, pressure and temperature monitoring, and more.

Configure and control data logging tests from your phone or tablet, from the first measurement through final documentation.

Connect two, three, even four Bluetooth Ralston gauges to FieldLab Mobile and monitor and log readings together into one unified Test Run.

Combine pressure and temperature readings, assign each reading to the appropriate Bluetooth-enabled Ralston Field Gauge, and add meaningful labels based on the customer, location, work order, or test point.
FieldLab Mobile is included free and for use with all Bluetooth-equipped Ralston pressure and temperature gauges.

Select engineering units, define logging intervals, and start and stop data collection remotely, giving you one place to follow your measurements throughout the test.

Set Maximum and/or Minimum Limits for a reading and display them visually on charts.
See graphic charts of completed Test Runs for quick review of how pressure and temperature readings changed throughout the test. See peak (high) and valley (low) values at a glance.
Test Runs with different measurement units display on multiple Y-axes for clear multi-variable charts.

Detailed Test Runs include customizable Title, Variable/Reading Labels, and Gauge Names to align with SOPs and provide clear test documentation. Test Runs include reference gauge information and optional calibration dates.
Export test results as PDF or CSV files, or save charts as PNG images for reports and presentations. Reports include reference gauge details and custom reading labels and titles that can be edited in the field, giving your test data the context needed for clear, traceable records and supporting SOP compliance.
