The AutoMeter Spek-Pro 2-1/6 Gauge Voltmeter with Peak Memory is a precision electrical system diagnostic tool designed for vehicles requiring real-time voltage monitoring and transient peak capture. This analog voltmeter reads from 0 to 16 volts across a full-sweep dial, providing immediate visibility into charging system performance, battery condition, and electrical load states during operation. The 2-1/16-inch diameter black face mount integrates into dash configurations or panel installations where continuous voltage observation is critical to diagnosing electrical anomalies.
Peak Memory functionality captures the highest voltage spike encountered during a test cycle, allowing technicians and vehicle operators to identify transient events that standard meters miss. The full-sweep analog gauge provides smooth needle response and eliminates the lag found in digital displays, making it easier to observe voltage fluctuations during engine cranking, load application, or electrical fault conditions. The electric operation and calibrated 0–16V range suit both standard 12-volt and auxiliary 24-volt systems, depending on application configuration. Compact dimensions (4.7 × 4.5 × 4.9 inches) and lightweight construction (0.65 lbs) enable rapid installation in mobile diagnostic setups or permanent vehicle mounting.
This gauge serves automotive technicians, off-road operators, marine installations, and fleet maintenance personnel who need reliable voltage trending without dependence on digital displays or external power sources. The peak-hold feature is particularly valuable during cold-start testing, alternator assessment under varying loads, and battery condition evaluation in field environments where transient voltage behavior reveals hidden electrical faults. AutoMeter's analog design prioritizes reliability in dust, vibration, and temperature extremes where electronic instrument failure creates diagnostic blind spots.
