## FieldLab Mobile Description
FieldLab Mobile is a powerful test-and-measurement app compatible with Ralston Instruments Gauges. Connect one or more Ralston Gauges to your iPhone or iPad via Bluetooth and perform tests and monitor live pressure and temperature readings.

LOG MULTIPLE GAUGES IN A SINGLE TEST RUN       
Connect multiple Ralston gauges at once and record pressure and temperature from every sensor simultaneously. Each reading is logged with a precise timestamp, so your complete test data lives in one place.

VIEW ALL READINGS ON ONE GRAPH              
All test readings appear on a single, time-based pressure and/or temperature chart. View multiple pressure and temperature trends together to spot correlations and pinpoint exactly when changes occurred during your test.

EXPORT TRACEABLE REPORTS              
Every export includes detailed information about the gauges used in the test: Manufacturer, model, and serial number, so your records meet traceability requirements. Share your results in the format that fits your workflow:
• PDF: A formatted test report with a reading summary showing high, low, and average values, the full chart, and a complete data table. Ready to email, print, or file for regulatory records.
• CSV: The full test run in a spreadsheet-compatible format for further analysis.
• Graph image: A simple color PNG image of the test run graph showing all readings, pressure, and/or temperature axis. 

EDITABLE TEST RUN TITLES, REFERENCES & READING NAMES            
Name your Test Run outputs to match work orders, customers or any SOP. Assign custom names to each pressure and temperature readings before or after a test. Label readings by location, function, or whatever makes sense for the job. When you review the graph or share the report, every data point is clearly identified. Name your gauges for asset tracking, nicknames, or any reference to help with traceability requirements. 

WORK FROM A SAFE DISTANCE              
Bluetooth connectivity lets you monitor tests from a safe distance while maintaining full visibility of live readings on your device, even from the cab of your truck or job-site trailer. Test data is logged on the gauge, so even if you lose connection, your data will be collected back to the FieldLab Mobile App when you reconnect. 

CHOOSE THE RIGHT GAUGE FOR YOUR APPLICATION              
Ralston offers a wide range of Bluetooth-equipped gauges, all compatible with FieldLab Mobile:
• Pressure gauges in ranges from vacuum to 30,000 PSI
• Dual pressure gauges with two independent sensors in a single unit
• Dual pressure + temperature gauges with temp measurement up to 302 F (150 C)
• Temperature-only gauges with temp measurement up to 302 F (150 C)

All models feature +/-0.1% full-span accuracy, a rugged IP67-rated housing that's dustproof and waterproof up to 1-meter submersion, and are powered by replaceable AA batteries. The gauges log data independently, so even if you walk out of Bluetooth range during a test, your test continues to log without interruption on the gauges and remains safe there until you reconnect.
