Gould Instruments

Features
Read full description

Gould Instruments is the field companion for technicians who test and certify fire-safety and water systems. Connect to your Bluetooth flowmeter, run the test, capture the readings, and hand over a finished report before you leave the site. BUILT FOR THE EQUIPMENT YOU ACTUALLY SERVICE • Fire hydrants and hydrant flow tests • Fire sprinkler systems • Fire hose reels • Fire booster pumps • Fire supply mains • Backflow prevention devices • Thermostatic mixing valves (TMVs) • Emergency showers and eyewash stations • Hydrostatic pressure tests BLUETOOTH GAUGE, NO MANUAL TRANSCRIPTION Pair directly with your Gould flowmeter over Bluetooth Low Energy. Live pressure and flow readings stream straight into the app, plot on a chart as the test runs, and are recorded against the right asset — no clipboard, no re-typing numbers back at the office. The app remembers your last gauge and reconnects automatically. WORKS WHERE THE WORK IS Plant rooms, basements, remote sites — the app is offline-first. Everything you record is stored on the device and syncs to the cloud once you're back in range. Start a job with no signal, finish it, and let it upload later. Nothing waits on a network you don't have. REPORTS ON THE SPOT Generate a professional test report the moment the job is done, complete with your test data, site photos and an on-screen customer signature. Upload your own document template so every report goes out in your company's format. Review past reports in the app and share them straight from your device. ASSET LABELS AND QR SCANNING Print QR labels for equipment straight from the app, then scan them on your next visit and the asset's serial number and description fill themselves in — no squinting at a faded plate. Tap to focus makes scanning quick even in poor plant-room light. Owner and tester contact details get labels too, so anyone on site can scan them into their phone. OWNERS, TEST KITS AND RETEST REMINDERS Keep your owner contacts and test kit register in one place, with each kit's serial and verification date on hand for the report. Every report you complete schedules its own retest reminder, so the next service date turns up on your phone instead of on a spreadsheet. EVERYTHING IN ONE PLACE • Live gauge readings with test charts • Site photos attached to the right test • Customer signature capture • Owner contacts and test kit register • Automatic retest reminders • Past reports kept on the device • Automatic cloud sync and backup Gould Instruments turns a day of paperwork into a day of testing.
