Extech EN300
5 合 1 环境测定仪
EN300 可测量湿度、温度、风速、光照度和噪音强度。坚固耐用的 5 合 1 环境测定仪，采用三脚架安装和 RS-232 PC 接口。配备大尺寸双液晶显示屏，可同步显示温度和风速或相对湿度。显示屏上的字符可逆向显示，具体取决于温湿度计-风速仪或光-噪音模式。具有数据保持、最小值/最大值、自动关机、电池低电量/超量程提示功能。内置的低摩擦叶轮可提高以 ft/min、MPH、m/s、km/h 和节为单位的风速精度。内置精密薄膜电容湿度传感器，可实现快速响应。内置热敏电阻，用于测量环境温度。K 型输入可测量最高 1300°C 的温度。利用精密光电二极管和校正滤光片进行余弦和色彩校正光测量。噪音测量采用 A 频率加权，响应时间短，符合 IEC 61672 标准的 2 级。配有 K 型热电偶探头、便携包和六节 1.5V AAA 电池。
