ES300甲醛检测仪 美国ESC公司 ES-300
ES300手持式甲醛检测仪，分辨率0.01ppm，适用于监测室内空气中的甲醛浓度，以及需要使用甲醛的工作环境空气中的甲醛浓度。
仪器具有单点测试和连续测试两种工作模式。连续模式下，可设定测试周期为0-480分钟的任意时间，LCD显示器每隔10秒更新一次读数，测试周期结束后，自动停止测试。测试过程中随时可查看整个测试时间内的平均值及第一个测量值。
ES300甲醛检测仪，采用独特的过滤器技术，可消除室内空气中常见的多种气体对甲醛测量的干扰，提高了测量的精度及可靠性。

ES300 formaldehyde analyzer America company ESCES-300
ES300 portable formaldehyde detector, the resolution of 0.01ppm, the concentration of formaldehyde in indoor airis suitable for monitoring, and the need to use formaldehyde working environment air concentrations of formaldehyde.
Instrument with single point test and continuous testingtwo kinds of work mode. Continuous mode, any time can be set test cycle for 0-480 minutes, LCD display is updated every 10 seconds reading, the completion of the test period, auto stop test. The testing process at any time to view the entire test period the average value andthe first measured value.
ES300 formaldehyde detector, using filter technologyunique, can eliminate the interference of common gasesin indoor air formaldehyde measurement, improves the precision and reliability of measurement.
