Part #HD50 - Handheld Distance Meter. For hard-to-reach or hazardous locations, such as elevator shafts or open stairways, the HD150 is the reliable choice for all your distance measurement applications. The 58-TLM200 is extremely versatile and safe, measuring indoors, out-doors, and hard-to-reach places or hazardous areas. The 58-TLM200 also measures linear distances, adds and subtracts distances, and calculates area and volume at the touch of a button.

Measures up to 165'
1/16" accuracy across entire range
Performs mulitple functions: distance, area, volume, continuous line, and indirect measuring using Pythagorus calculation
Automatically turns off after 5 minutes if not in use to conserve battery life
4 selectable measuring points: front, 1/4" x 20 mounting thread, rear, rear-pin for corner measurements
The HD50 Handheld Distance measuring device offers the best value for the price in the entire measuring meter category. It's small (smaller than a blackberry) with a rubber grip for easy handling. The HD50 performs all the necessary functions needed by the pros. This "non-contact" measuring of up to 165 ft. (50m) allows one-person to measure difficult-to-reach or hazardous locations. Accuracy of 1/16" (1.5mm) across the entire measuring range reduces measuring errors even over large distances. 'Distance','Area', 'volume', and 'continuous measurement' keys allow direct access to measurement functions, and eliminate math errors.
