J2-2 Optical Theodolite Product Introduction (English)
The J2-2 optical theodolite is a precision optical angle-measuring instrument suitable for engineering surveys, industrial measurements and geodetic surveys. It features an erect-image telescope with bright and clear field of view, providing excellent imaging quality. The telescope offers 30x magnification with a 40mm objective lens aperture, minimum sighting distance of 2 meters and multiplication constant of 100. Equipped with a digital reading system, the instrument ensures quick and reliable measurement data acquisition. The vertical circle incorporates an automatic index compensator, making vertical angle measurements more convenient and accurate. The J2-2 adopts an elevated and widened integrated bracket design that is compatible with various infrared distance meters. With horizontal direction standard deviation of ±2″ per set and vertical angle measurement standard deviation of ±6″, it meets high-precision measurement requirements. This instrument is widely used in triangulation and traverse surveys, precision engineering measurements, tunnel and mine construction surveys, cadastral surveys, deformation monitoring, and can also be applied in large machinery installation and metrology work. The instrument weighs 6kg net and features a three-screw base design for convenient field operation. 12421
產(chǎn)品特點與技術(shù)優(yōu)勢
J2-2光學(xué)經(jīng)緯儀采用半運動軸系設(shè)計，具有摩擦力矩小、耐磨性好的特點，軸系中的鋼珠和軸套錐面具有自動歸心作用，溫度變化對儀器影響較小。讀數(shù)系統(tǒng)采用對徑符合數(shù)字讀數(shù)方式，使用透射式度盤和1:1透鏡轉(zhuǎn)像系統(tǒng)，配合移動光楔測微器實現(xiàn)精確測量。望遠鏡鏡筒上下均裝有光學(xué)粗瞄準器，便于正倒鏡觀測時進行粗瞄。儀器內(nèi)置反光板，可在夜間觀測時照明分劃板。分劃板附有保護玻璃，可清除污點而不損傷十字絲。儀器采用懸擺式補償器，能有效消除儀器整平后的殘余誤差對豎盤讀數(shù)的影響，補償精度達±0.3″，補償范圍為±3′。71317
Product Features and Technical Advantages
The J2-2 optical theodolite employs a semi-kinematic axis system design with low friction torque and excellent wear resistance. The steel balls and conical surfaces in the axis system provide automatic centering function with minimal temperature influence. The reading system adopts diametrical coincidence digital reading method, utilizing transmitted circle and 1:1 lens imaging system combined with movable optical wedge micrometer for precise measurements. Both upper and lower sides of telescope barrel are equipped with optical rough sights for coarse aiming during direct and reversed position observations. The built-in reflector plate enables reticle illumination for night observations. The protected reticle with cover glass allows cleaning without damaging crosshairs. The pendulum-type compensator effectively eliminates the influence of leveling residual errors on vertical circle readings, achieving compensation accuracy of ±0.3″ within ±3′ compensation range. 71218
