4合1空氣速度計(jì) - 風(fēng)速計(jì)、濕度計(jì)、照度計(jì)、溫度計(jì)
空氣流速和溫度或濕度和溫度的同時(shí)讀數(shù)
**的光電二極管和彩色濾光片的光傳感器，光譜滿足壓燃式發(fā)動(dòng)機(jī)
標(biāo)準(zhǔn)的K型熱電偶SMP輸入杰克適合所有類型的K探針
力士/英尺燭光可選按面板上的按鈕
該hhf81風(fēng)速計(jì)可以測(cè)量空氣流量，濕度，溫度和光照。內(nèi)置的微處理器電路保證了優(yōu)異的性能和精度。該hhf81可以跟蹤的*大值和*小值隨著電流讀數(shù)。在你選擇的hhf81結(jié)顯示流量，米每秒，每小時(shí)公里，英里每小時(shí)，甚至每分鐘英尺。
該hhf81依賴于低摩擦球軸承安裝盤的設(shè)計(jì)在高和低的空氣速度提供高精度。葉輪提供了良好的精度（±3到4%）和能力來衡量的微風(fēng)（0.3米/秒）。
溫度讀數(shù)，該hhf81內(nèi)部有一個(gè)熱敏電阻或是任何K型熱電偶與SMP公連接器兼容，并**到±1°C + 1%的閱讀。濕度傳感器測(cè)量到95%相對(duì)濕度的變化，利用快速響應(yīng)的高精度薄膜電容傳感器。
光測(cè)量利用專用的光電二極管和彩色濾光片的光傳感器。
