賓得ETH-502電子經(jīng)緯儀產(chǎn)品介紹（中文）
賓得ETH-502電子經(jīng)緯儀是一款高精度工程測量儀器，采用雙面板液晶中文顯示設(shè)計，操作直觀便捷。該儀器具備30倍放大倍率，有效孔徑45mm，視場角1°30’，最短視距1.35米，測角精度達(dá)到2秒級，最小顯示刻度可切換至1秒/5秒模式。主機(jī)集成化設(shè)計，含電池僅重4.5-4.6kg，便于野外作業(yè)攜帶。儀器支持盤左盤右雙面測量，垂直角可自動轉(zhuǎn)換為坡度百分比，水平角具備任意位置置零和鎖定功能。采用Hi-MH2000mAh充電電池或堿性干電池供電，續(xù)航時間分別達(dá)20小時和25小時，并配備自動關(guān)機(jī)功能以延長使用時間。光學(xué)系統(tǒng)經(jīng)過優(yōu)化，在弱光環(huán)境下仍能保持清晰成像，望遠(yuǎn)鏡調(diào)焦范圍覆蓋0.5米至無限遠(yuǎn)。雙面16×2字符LCD顯示屏可同步顯示垂直角與水平角數(shù)據(jù)，支持度分秒格式切換。儀器具備JIS4級防水性能，橫水準(zhǔn)氣泡精度30"/2mm，圓氣泡精度8 /2mm，適用于建筑安裝、道路橋梁、礦山測繪等多種工程場景。136
Pentax ETH-502 Electronic Theodolite Product Introduction (English)
The Pentax ETH-502 Electronic Theodolite is a precision engineering instrument featuring dual-panel LCD displays with Chinese/English interface. With 30x magnification and 45mm effective aperture, it provides a 1°30 field of view and 1.35m minimum focusing distance, achieving 2-second angle measurement accuracy with 1-second/5-second display resolution options. The compact main unit weighs only 4.5-4.6kg including battery, optimized for field operations. It supports face-left/face-right measurements with vertical angle conversion to slope percentage, and offers horizontal angle zero-setting at any position plus locking function. Powered by 2000mAh Hi-MH rechargeable battery (20-hour runtime) or alkaline batteries (25-hour runtime), it includes auto power-off function for energy efficiency. The enhanced optical system ensures clear imaging in low-light conditions, with telescope focusing range from 0.5m to infinity. Dual 16×2 character LCD screens simultaneously display vertical/horizontal angles in DEG/MIN/SEC format. Featuring JIS4 waterproof rating, 30"/2mm lateral level bubble and 8 /2mm circular bubble, it s widely used in construction alignment, bridge monitoring, mining survey and other technical applications. The instrument combines operational simplicity with reliable performance for professional measurement tasks.41419
