筆式測振儀PVB-82特點
●應(yīng)用于工業(yè)振動監(jiān)測：工業(yè)機械振動。振動水平對機器狀態(tài)有很好的指導(dǎo)作用。結(jié)構(gòu)的不平衡、不平衡和松動會引起振動水平的增加，這是維修的必然標(biāo)志。
●筆型數(shù)字測振儀，振動傳感器是內(nèi)置的，都在一個。
●加速度、速度測量，有效值測量值。
●公制和英制單位顯示。
●頻率范圍10 Hz至1 kHz，靈敏度相對滿足ISO 2954。
●微機電路，智能化的功能，精度高。
●液晶顯示，方便讀取。
●成套測試針和磁性底座的標(biāo)準(zhǔn)配件。
●內(nèi)置低電池指示器。
●重型緊湊的外殼。
●IP65防護等級。
●體積小，重量輕。
●軟手提箱是可選配件
