F.W.Boll公司新近推出一种超低频检测仪。该检测仪可用来测量由交流电器所产生的对人体有潜在危害的磁场强度。私立和政府机构正在调查研究由电力传输线、计算机、微波及其它电源产生的可能导致癌症、白血病以及胎儿畸形的电磁场辐射。这种手持式超低频检测仪的主要特点是:具有3位半数字的液晶显示,可测出任一种毫高斯或高斯级的磁场强度。使用简单,仅有1个启闭开关和1个量程开关。只要打开这两个开关,将检测仪器置于被测源附近,便可直接读数。该检测仪的测量误差仅为±1％。可分辩1～10毫高斯的辐射量。其电源为可更换的9V电池,更换一次电池可连续使用230小时。
F.W.Boll company recently introduced a ultra-low frequency detector. The detector can be used to measure the magnetic field generated by the AC electric potential hazards to the human body. Private and government agencies are investigating electromagnetic field emissions from power transmission lines, computers, microwaves and other power supplies that can cause cancer, leukemia and fetal malformations. The main features of this hand-held ultra-low frequency detector is: with 3 and a half digital LCD display, can measure any kind of milligauss or Gaussian magnetic field strength. Simple to use, with only 1 opening and closing switch and 1 range switch. Just open the two switches, the detection equipment placed near the measured source, you can directly read. The detector measurement error is only ± 1%. Can be distinguished from 1 to 10 milligaurs of radiation. Its power is replaceable 9V battery, replace the battery can be used continuously for 230 hours.
