Multi-Field EMF RF Gauss Meter
The TENMARS TM-190 combines electromagnetic field, electric field and RF strength measurements in a single handheld instrument. It covers low-frequency magnetic fields up to 2000 mG and RF signals up to 3.5 GHz. A 2.4 inch colour TFT LCD provides four-digit readings with selectable language options. The unit weighs about 120 g and fits easily in a tool bag.
Sustained measurement behaviour
Continuous operation runs for approximately 8 hours on three AAA alkaline batteries or via USB mini-B power. The sample rate updates every 6 seconds, giving stable trends during long surveys. Accuracy holds at ±2 dB for RF at 2.45 GHz and ±(15%+100 digits) for magnetic fields across the 50/60 Hz band. Operating limits are 5 °C to 40 °C below 80 % RH.
Pre-purchase checklist
Confirm the 50 MHz to 3.5 GHz RF range covers the frequencies you need to monitor. Verify that the magnetic range of 0.02 to 2000 mG and electric range of 50 to 2000 V/m suit your application. Ensure you have AAA batteries or a USB mini-B source for power. The meter includes a three-year parts and one-year labour coverage period.

Questions about this item
How long can the TM-190 run on its three AAA batteries during all-day EMF surveys?
The meter delivers approximately 8 hours of continuous operation from three 1.5 V AAA alkaline cells, and it can also be powered through the USB mini-B port for longer sessions.
What power source must I already have to start measuring with the TM-190?
You need three standard 1.5 V AAA alkaline batteries, which are not included, or a USB mini-B cable connected to any 5 V USB power supply or computer port.
Will the TM-190’s 50/60 Hz magnetic and electric field ranges work alongside older 50 Hz-only test gear I still use?
Yes, the low-frequency sensors are specified at 50/60 Hz with ranges of 0.02–2000 mG and 50–2000 V/m, matching the frequencies used by legacy single-frequency instruments.
