SZG-20B觸式手持式數(shù)字轉(zhuǎn)速表Tachometer
概述:
SZG-20B型觸式手持式數(shù)字轉(zhuǎn)速表是袖珍型高精度轉(zhuǎn)速表,它采用光電變換原理,通過接觸方式能測(cè)量電機(jī)和各種機(jī)器設(shè)備的轉(zhuǎn)速和線速度,儀表采用五位液晶數(shù)字顯示,直觀準(zhǔn)確,使用方便,體積小,便于攜帶,適用范圍廣。
SZG-441光電手持?jǐn)?shù)字轉(zhuǎn)速表,式一臺(tái)測(cè)量范圍寬,精度高,功能多,使用方便的轉(zhuǎn)速表,可測(cè)量轉(zhuǎn)速,線速度及頻率。并具有記數(shù)功能。與一般非接觸式手持?jǐn)?shù)字轉(zhuǎn)速表相比體積小,造型精巧,手感更好。使用時(shí)在被測(cè)旋轉(zhuǎn)物體上貼一塊反射標(biāo)記,將轉(zhuǎn)速表的可見光點(diǎn)對(duì)準(zhǔn)反射標(biāo)記即可進(jìn)行測(cè)量。感表有最大值,最小值報(bào)警功能,能儲(chǔ)存最后一次測(cè)量值及本次測(cè)量過程中最大值,最小值。

SZG-20B touch hand-held digital tachometer Tachometer
Summary.
SZG-20B touch hand-held digital tachometer is a type of high precision tachometer, it adopts photoelectrictransformation principle, through the contact way to test linear velocity and speed motor and all kinds ofmachinery and equipment, instrument using five LCD digital display, intuitive and accurate, convenient use,small volume, convenient carrying, wide application range.
SZG-441 photoelectric handheld digital tachometer,measuring range is a wide, high accuracy, multiple functions, convenient use of the tachometer, measuringspeed, speed and frequency. And with counting function.With the general non-contact handheld digital tachometercompared with small volume, beautiful appearance, feel better. With a piece of reflective markers in rotatingobjects to be measured using, tachometer visible lightreflective markers were measured at. A sense of amaximum value, minimum value alarm function, can storea maximum last measurement value and themeasurement process, the minimum value.
