阿美特克Ametek冷干體爐JOFRA -125A型|B型的產(chǎn)品介紹

-125是2006年底新推出的冷型干體爐，它的溫度可以-90℃，目前是溫度，重量輕的干體爐。-125采用了AMETEK的自由活塞制冷技術(shù)，冷卻壓縮機和加熱元件結(jié)合，使加熱和制冷時間大大縮短。機內(nèi)冷媒使用很少的氣體，不使用氟利昂和液體制冷，合法規(guī)要求，保護大氣環(huán)境。它在計量，制藥，液化天然氣，食品，醫(yī)院等行業(yè)會有適合的應(yīng)用。
在常溫下可以實現(xiàn)-90℃到125℃的溫場，可以對低溫傳感器進行校準(zhǔn)。作為目前世界上溫度的干體式溫度校準(zhǔn)儀，125重20公斤，卻可以實現(xiàn)快速降溫。由于采用了的技術(shù)，125的技術(shù)指標(biāo)接近實驗室液槽，同時相對于其它帶制冷功能的干體式溫度校準(zhǔn)儀實現(xiàn)了的溫度范圍跨度。125B還具有各種測試接口，可以直接測量熱電阻，熱電偶等各種被校傳感器的信號，可以在不使用計算機的情況下，對溫度傳感器實現(xiàn)全自動的校準(zhǔn)，并且可以把校準(zhǔn)結(jié)果上傳到計算機。
