The Tenmars TM-191A is a single-axis EMF (Gauss) meter for 30Hz~300Hz magnetic fields. It reads in mG or µT over 200/2000 mG and 20/200 µT ranges on a 3½ digits LCD, with ±(2.5%±6dgt) accuracy at 50Hz/60Hz, data hold, MAX hold and about 100 hours of battery life.
The Tenmars TM-191A is a handheld magnetic field meter with a single-axis sensor and a frequency response of 30Hz~300Hz. It is capable of measuring the electromagnetic field radiation intensity that is produced by electric transmission equipment, power lines, air conditioners, refrigerators, computer monitors, video/audio devices and similar sources.
The reading can be displayed in milli-Gauss or micro-Tesla, over the ranges 200/2000 mG and 20/200 µT, with a resolution of 0.1/1 mG or 0.01/0.1 µT and an accuracy of ±(2.5%±6dgt) at 50Hz/60Hz. The 3½ digits LCD shows a maximum reading of 1999 and is updated 2.5 times per second.
The meter is powered by one 9V battery (NEDA 1604, IEC 6F22 or JIS 006P) that lasts approximately 100 hours. It weighs about 170 g and measures 140 × 65 × 37.5 mm.
