NR型數字深水溫度計
此數字深水溫度計主要用于測量深水溫度，也可以用來測量任何無腐蝕性介質的溫度。測量范圍可達-45℃～125℃。此溫度計在0℃～40℃范圍內標定。

技術指標：
測量范圍：-45℃～125℃
適用水深：40m（電纜長度依用戶需要配備)
電 源：支流4.5v，3節5號電池
功 耗：zui大電流80mA
誤 差：0℃～40℃：zui大*.5℃
       -45℃～125℃: zui大誤差2℃
分 辨 力：0.1℃
響應時間：自然水溫下不大于6秒。
顯示：3位半LED顯示，小數點后1位。
 

使用方法：
    將傳感器放入水中欲測溫度位置，按下表殼上的按扭，數秒鐘后即可顯示所測溫度值。

更換電池：
    擰開后蓋上的螺釘，取下后蓋，即可按電池盒上的正負極安裝電池。

注意：
    電路板上的兩個電位器已標定好溫度計的精度，請不要動。
