Discuss this service →Ultrasonic Flow Measurement & Verification
Non-invasive clamp-on liquid flow measurement for operating pipework using our Dynasonics TFX Ultra (DTFXB-ZN-DKNN-FN) and QT621 portable ultrasonic flowmeters. Suitable for temporary surveys, flow verification, troubleshooting and pump/valve performance checks without cutting into the pipe.
Request flow measurement →Earth Ground Loop & Leakage Current Checks
Earth-ground loop resistance and AC leakage-current checks on suitable multi-grounded systems using the Fluke 1630-2 FC clamp. The clamp method can test without disconnecting parallel grounds and is useful where auxiliary stakes are impractical.
Request earth testing →Vibration & Machine Condition Screening
Front-line vibration screening for motors, pumps, fans and other rotating machinery using the Fluke 805 FC. The Fluke 805ES external sensor extends measurements to crowded, guarded and difficult-to-reach locations for condition trending and maintenance decisions.
Request vibration screening →Multi-Point Power Quality Monitoring
Power-quality surveys using four Elcontrol NanoVIP CUBE analyzers, enabling coordinated measurements at multiple distribution points. We assess voltage, current, power, power factor, harmonics, load balance and electrical operating trends to support troubleshooting and energy-performance investigations.
