Our adjustable pipettes have been widely used for sampling and dispensing liquids when accuracy, precision and convenience are required. They are available in 8 volumes ranging from 0.1 to 5000 µl, and use standard pipette tips. All Donglin pipettes have tip ejection, and are factory calibrated. The major features include: ·Ergonomic and lightweight design ·High accuracy and precision ·Easy-to-read digital volume display ·High chemical resistance of piston and ejector for durability ·One-handed volume setting for right-or left-handed users ·Easy Calibration technology provides calibration adjustments without tools
With different external probes, the gauge can be applied to measuring thickness of non-magnetic coating on magnetic metal substrate, as well as non-conductive coating on non-magnetic metal substrate. Five types of probes (F400, F1, F10, N1, CN02) are available for different application. F10 probe measures up to 10mm. Two measuring modes: single or continuous, changeable. Two calibration methods can be applied to the gauge; And the system error of the probe can be corrected with the basic probe calibration method. Measured values and user information are shown on a large, easy-to-read LCD. A display back light ensures easy reading of screen data in poorly-lit conditions. Measuring status indicator showing the measuring status. n. Measuring Principles The gauge adopts two thickness-measuring methods: magnetic induction method and eddy current method. insulating coatings on all non-ferrous metals and on austenitic stainless steels, e.g. paint, anodizing coatings, ceramics, etc. applied on aluminum, copper, zinc die-casting, brass, etc. Working Conditions Working temperature£º -10¡æ¡«£«50¡æ; Storage temperature£º-30¡æ¡«£«60¡æ; Relative humidity: ¡Ü90£¥; The surrounding environment should avoid of vibration, strong magnetic field, corrosive medium and heavy dust.
