This unit
The Fluke 189 is a high-resolution True RMS digital multimeter built for professional electronics troubleshooting, service, and preventive maintenance. Its dual 5½-digit display - primary 50,000 counts, secondary 5,000 counts - combined with a 40 Hz analog bar graph delivers real-time signal observation across AC and DC domains. With 0.025% basic DC voltage accuracy and 100 kHz AC bandwidth, the 189 captures precise measurements in complex industrial and field environments.
Data logging stores up to 3 days of continuous readings with timestamp correlation, enabling intermittent fault detection without bench presence. MIN/MAX/AVG recording with peak capture as fast as 250 µs pinpoints transient anomalies.

Fluke 189 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Fluke 189. Calibration covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Fluke 189 faults: vacuum gauge filament failure (ionization gauges), spectrophotometer D2 lamp end-of-life, wavelength motor failure, strain indicator front-panel binding post corrosion, pH electrode conditioning failure. Most specialty laboratory instruments fail at their electromechanical interfaces first — vacuum gauge connectors and filament assemblies, spectrophotometer lamp housings and motor drives, strain indicator binding post corrosion. Component-level repair is standard; manufacturer support for legacy instruments is often limited, making third-party bench repair the practical path.
