mso-hansi-font-family:"Times New Roman"">一、水泥比長(zhǎng)儀產(chǎn)品簡(jiǎn)介:
mso-hansi-font-family:"Times New Roman"">水泥比長(zhǎng)儀主要用于測(cè)定水泥膠砂試件各齡期的干縮率和膨脹水泥各齡期的膨脹率。用于按《水泥膠砂干縮試驗(yàn)方法》(GB751-81)的要求測(cè)定水泥試件各齡期的干縮率及按JC313-82標(biāo)準(zhǔn)測(cè)定膨脹率。BY-160 mso-hansi-font-family:"Times New Roman"">型用于測(cè)定砂漿BY-354 "Times New Roman"">型用于混凝土。
mso-hansi-font-family:"Times New Roman"">二、水泥比長(zhǎng)儀主要技術(shù)參數(shù):
1、千分表最小刻度值:0.001mm
2、千分表最大量程:3mm mso-hansi-font-family:"Times New Roman"">;電子千分表7mm
3、測(cè)量范圍:
a、砂漿用ISOBY-160型比長(zhǎng)儀;
mso-hansi-font-family:"Times New Roman"">千分表:158mm-165mm
mso-hansi-font-family:"Times New Roman"">電子千分表:158mm-161mm
b、混凝土用ISOBY-354型比長(zhǎng)儀
mso-hansi-font-family:"Times New Roman"">千分表:354mm-357mm
mso-hansi-font-family:"Times New Roman"">電子千分表:354mm-361mm
4、測(cè)頭平面直徑:6.5mm
5、標(biāo)準(zhǔn)桿基長(zhǎng):
a、砂漿用ISOBY-160型比長(zhǎng)儀158mm
b、混凝土用ISOBY-354型比長(zhǎng)儀354mm
mso-hansi-font-family:"Times New Roman"">三、水泥比長(zhǎng)儀結(jié)構(gòu)特點(diǎn):
mso-hansi-font-family:"Times New Roman"">比長(zhǎng)儀是由:1 "Times New Roman"">、千分表; 2 "Times New Roman"">、上測(cè)頭; 3 "Times New Roman"">、90°V型槽支架; 4 mso-hansi-font-family:"Times New Roman"">、下測(cè)頭; 5 "Times New Roman"">、標(biāo)準(zhǔn)桿; 6 "Times New Roman"">、底座等組成。它具有使用方便、測(cè)量精度高、速度快、讀數(shù)清楚等優(yōu)點(diǎn)。為了滿足用戶的使用要求,支架采用V mso-hansi-font-family:"Times New Roman"">型槽式,上下測(cè)頭采用平面測(cè)頭,這種方法提高了測(cè)量精度和準(zhǔn)確性,可供廣大用戶試驗(yàn)檢測(cè)用。
