"best gauss meter overallSo, Tenmars TM-192 is the best gauss meter overall that we find on the market. It measures with its 3-axis internal orthogonal sensors to ensure accuracy. Also, itâ??s handheld and easy to carry. To evaluate a wide variety of ELF magnetic fields, regardless of the measuring angle, three internal orthogonal sensors are used for this device. The device is developed to get a more fast, accurate, and clear way for users to calculate the levels of magnetic field energy across power lines, consumer products, and industrial equipment. The device is a relatively cheap, portable device designed and optimized for measuring magnetic field intensity from 30Hz to 2000Hz at various bandwidths. MicroTesla (mT) or milli Gauss (mG) are the readings display units for this device. The functionality of data hold (HOLD), maximum hold (MAX), and minimal hold (MIN) is provided in this device. Both Auto Range and P Manual Range mode is provided. Room for data logging of memory size can accommodate 500 data sets. Aside from that, it functions for calendar and time. It also provides a low-level battery indication. The function of the overload display (OL) is given as well."
