世界上zui小的水銀監(jiān)測(cè)儀
2B-Tech通過(guò)開(kāi)發(fā)HERMES個(gè)人水銀監(jiān)測(cè)儀(PMM)在基于紫外線(xiàn)的水銀監(jiān)測(cè)儀小型化方面邁出了下一步降铸。HERMES的尺寸為4 x 3 x 1.5英寸,重量?jī)H為0.75磅(340克)摇零。它有一個(gè)內(nèi)置的定位系統(tǒng)推掸,以便水星測(cè)量可以隨著地理位置不斷記錄。通過(guò)將光路折疊成“U"形驻仅,可以實(shí)現(xiàn)15厘米的光路長(zhǎng)度谅畅,從而能夠?qū)Νh(huán)境空氣中的汞進(jìn)行極其靈敏的測(cè)量。
