DZH-30 Electronic Altimeter

Product Overview

This instrument is a digital height-measuring device, suitable for measuring tree height in forestry surveys and also applicable to applications requiring distance, angle, and height measurement, such as power line inspection, tower erection, freight handling, telecommunications, and railway maintenance. It features distance and angle measurement (AD) functions, enabling simultaneous measurement of angle, slant range, and horizontal distance. It also offers two-point height measurement (2H) and three-point height measurement (3H) modes. The instrument employs a laser sight for aiming and is powered by a rechargeable lithium battery, providing approximately 8 hours of continuous operation on a full charge; if no operation is performed for 5 minutes, the instrument automatically shuts down. It can store and display up to 996 height measurement records. Height compensation is available in handheld mode, and a distance offset can be set. The instrument supports both handheld and fixed mounting; when used in fixed mode, it must be mounted on a tripod.
