Replacement and backup battery packs for digital height gauges and height gauge control panels and displays keep tools operating without AC power. Height gauge power supplies, or AC adapters, draw electricity from standard wall outlets, ensuring uninterrupted power over long operating periods. Battery pack chargers for height gauges allow height gauge battery packs to charge when not in use.

Height gauge dust covers protect height gauges from dust, debris, and other particulate or liquid contaminants. They allow for height gauges to be left in their operating position when not in use.

Height gauge control panels have a screen with a keyboard and/or touchscreen and are used to program and control height gauges, and may include an onboard printer. External printers connect to height gauges via common connection ports such as USB or RS232 and allow the operator to product a hard copy of measurements without needing to connect to a computer with SPC software. Accessories include rolls of printer paper.

Components and accesories such as fine adjustment systems may be installed on compatible digital or vernier height gauges to add a manual fine adjustment to manual-travel gauges.
