Product identity

The Buyers Products B40B45 is a DC hour meter built for automotive service and shop environments. It records operating time on equipment powered between 10 and 80 volts DC.

Voltage range limits

The meter functions only within the stated 10 to 80 VDC window. Systems outside this range will not drive the counter, so the device cannot track hours on higher-voltage or lower-voltage circuits.

Panel cut-out diameter

A 1.88 inch diameter opening is required to mount the gauge in a panel or dashboard. Installers must verify that their enclosure can accommodate this exact cut-out size before purchase.

Questions about this item

Should I choose the B40B45 hour meter for a 10 VDC or an 80 VDC system?

The meter operates across the full 10 VDC to 80 VDC range, so a single unit works on any supply within those limits.

What does the 1.88 inch diameter mean when the meter is installed in a panel?

The 1.88 in. diameter is the cut-out size required for a standard round panel opening.

How does the 10-80 VDC input range affect wiring in a real machine?

The wide range lets you connect directly to low or high voltage DC circuits without an external converter.
