描述

產品名稱:      相對濕度數據記錄儀
生產廠商:      MICROEDGE INSTRUMENTS (CANADA)
產品系列:      SITE-LOG
產品編號:      LRHT-1


SITE-LOG LRHT-1(內部傳感器)是2通道電池供電的獨立數據記錄器,在非易失性閃存中最多可存儲8 MB數據。其鋁製外殼使它在最惡劣的工業環境中也表現出色。
即插即用USB端口和通用的自定義公式簡化了通信和工程單位轉換。 LRHT-1 / LRHT-2記錄儀由Sensirion高性能數字RH傳感器提供動力,非常適合需要精確測量的科學和實驗室應用。
只需將記錄儀插入計算機的USB端口,軟件即可自動識別記錄儀並處理配置,下載,圖形查看等。

特徵:
  • 8 MB內存大小
  • USB和串行接口均具有高達115200 bps的自動波特率
  • Sensirion RH數字傳感器
  • 功能強大的軟件,用於配置,下載,繪圖,分析和警報報告
  • 可配置的警報控件/激勵控件
  • 廣泛的採樣間隔選擇(從1秒到12小時)
  • 堅固的鋁製外殼
  • 帶塗層的PCB可以防止潮濕,腐蝕和發霉。
