Did the meter change? Was the second meter you used distinguishing between low and high frequences of the same ranges that the Multidetector does? Otherwise, it might miss frequencies. What was the 2nd meter? What was the frequency range found by the two? Did you take the initial readings with the Multidetector yourself, or did someone else take them? I have found the Detector to be extremely useful, and not to indicate a field where there is none. Dave Stetzer likes it. Have others used it? Emil, you carry this one. What do you think of it?

Guest guest Posted January 23, 2006 Report Share Posted January 23, 2006 Hello Shivani, no, you are mixing two different things. The Multidetektor II is a meter for lowfrequencies, and is not good. The HF Detektor II Profi is a meter for high frequencies (RF) and is not bad, but today not according to present standards. (Btw. the HF Detektor II Profi is better than the new Spectrans!) Neither of the two meters distinguish between frequencies, nor do they measure frequencies, nor do they detect frequency ranges.. The Multidetektor only measures up to 20 kHz, not higher, and the values are 10 times higher than is. And does not detect german railway frequency fields. The values of detected magnetic fields between 50 and 100 Hz are displayed too low. It is nice that the LED's are flickering, but they do not represent real values. The meter I use is sensible up to 400 kHz, but that is not so important. But my meter needs to be grounded for electrical fields.

Guest guest Posted January 29, 2006 Report Share Posted January 29, 2006 HI Shivani, Yes, I am very familiar with it. Its usefulness depends on what information you are seeking. This is true of all meters. If you want a very sensitive meter which covers a wide range of frequencies for both electric and magnetic fields, this is a good meter. If you need high accuracy, high resolution, more durability, or need to look at specific frequencies, you will should use a different piece of equipment.
