    Product Details

    Japan brand B series automatic levels feature enhanced reliability under all environmental conditions. Tough and compact bodies are more tightly sealed against water, humidity and dust (IPx6). The B series levels provide quick setup, easy sighting, and superior durability against vibration and shock, ensuring the increased productivity over an extra-long period of time.

    Superior Telescope

    Optimally designed telescope provides exceptionally bright and sharp view that reduces operator's eye strain. Ultra-short focus distance of 20cm (7.9in.) from end of telescope makes it easiest to use in confined locations.

    Quick Collimation

    Two knobs of endless horizontal motion drives can be operated with either hand for fast and easy aiming. Horizontal Angle Measurement Horizontal angles can be read in 1° or 1 gon units. Freely rotatable circle allows any angle reading from zero. Right angles can be quickly set for layout and alignment tasks. The readout window is conveniently located on the instrument base - directly below the eyepiece.

    Stadia

    The stadia lines on the reticle allow distance measurements. Simply multiply the staff length between the top and bottom stadia lines by 100.

    Easy To Adjust

    Reticle adjustment is made with one screw. Circular levels vial is adjusted with two screws. Both adjustments are simple and fast with provided tools.

    Frequently Asked Questions

    What is the water resistance rating of the B series automatic levels?
    The B series levels feature a tough and compact body that is tightly sealed against water, humidity, and dust, achieving an IPX6 (EC 60529:2001) protection rating.
    What is the minimum focus distance of the B20 telescope?
    The B20 telescope has an ultra-short focus distance of 0.2m (7.9in.) from the end of the telescope, and 0.3m (1ft.) from the instrument center, making it highly convenient for use in confined locations.
    How do the horizontal motion drive and angle measurements work?
    It features a clampless, endless, double-sided knob system for horizontal motion drive. Horizontal angles can be read in 1° or 1 gon units via a readout window located directly below the eyepiece, with a freely rotatable circle that allows angle reading from zero.
    What is the leveling accuracy of the B20 model?
    For a 1km double run leveling, the standard deviation accuracy is 0.7mm (0.03in.) without a micrometer, and 0.5mm (0.02in.) when using a micrometer.
    What type of compensator is integrated into the B series?
    The instrument is equipped with a pendulum compensator featuring a magnetic damping system, providing a setting accuracy of 0.3" and a working range of ±15'.
    What is the operating temperature range for the B20?
    The B20 automatic level is designed to operate reliably in temperatures ranging from -20 to +50°C (-4 to +122°F).
