RSM系列 高精度多功能房間壓力監(jiān)測儀-德威爾Dwyer
RSM系列 高精度多功能房間壓力監(jiān)測儀為需要監(jiān)測低微差壓的重要場合而設(shè)計。它能用于象醫(yī)院隔離房這樣需要保護(hù)的環(huán)境中監(jiān)測正壓，負(fù)壓或差壓。RSM是一整套系統(tǒng)，帶背光的LCD數(shù)顯，帶有用戶自定義的界面，可通過觸摸屏直接設(shè)置壓力，安全，校準(zhǔn)和報警等的設(shè)定：密碼保護(hù)，紅綠LED指示帶聲音報警，也可延時報警等。RSM為NEMA 1 (IP20)的防護(hù)，采用阻燃塑料用于室內(nèi)。差壓顯示能精確到0.001英寸水柱。
