VTM125B
This 52mm mechanical voltmeter is manufactured to military OE specifications with the NSN part number 6625-01-180-6542. It is designed as a replacement component for Humvee M998 vehicles, and also fits M35 and M939 series military trucks. The gauge monitors battery and generator voltage with a reading accuracy of ±0.2V, serving military vehicle repair distributors and government fleet contractors. The unit features a round dial with color-coded BATT and GEN zones, and a thickened housing with IP54 dustproof rating. Two alternative models, DY206B and DY203D, share the same installation dimensions as VTM125B, providing flexible options for commercial parts procurement.
The voltmeter adopts a mechanical movement structure, with voltage reading error controlled within ±0.2V across its measuring range. During product development, each design undergoes over 500 vibration and temperature cycle tests to validate structural stability. The unit also completes 2000 hours of continuous power-on aging testing, with pointer movement remaining smooth without jamming after the test.
The outer casing is made of iron with a thickened structure, reaching IP54 dustproof level. This construction provides resistance to mud, dust and moisture in field operating environments. The metal terminals receive anti-corrosion treatment, and the pointer shaft uses wear-resistant materials to support long-term operation.
The 52mm round dial is divided into color-coded BATT and GEN areas. This layout allows vehicle operators to identify voltage readings with reduced visual scanning time, supporting operation during off-road driving conditions.
The voltmeter is engineered to match the installation specifications of Humvee M998 vehicles, and is also compatible with M35 and M939 series military trucks. It serves as a direct replacement part for the original factory voltage gauge on these models.
The gauge uses a standard 52mm mounting size, matching the dashboard cutout dimensions of target vehicles. It is equipped with a double-terminal connector that aligns with original wiring harness dimensions. No additional modification is required for installation, which can shorten vehicle maintenance downtime for repair operations.
