Introduction：
The HMDA 1545 is a magnetic field meter with display + loop antenna manufactured by Schwarzbeck (Germany) and distributed by EUTTEST, which shows the measured magnetic field values directly on the probe. Yes, you don't need to configure an external receiver to read the data, which is very useful for laboratories with a small budget.
Unlike low-sensitivity passive meters, this intensity meter has a detection threshold of +46 dBmA/m (200 mA/m) and also operates in the low-field intensity range, with magnetic field strengths up to 120 dBmA/m (1 A/m) in the insensitive range.
When there are many strong signals or frequencies of interest, the HMDA1545 can be used as a magnetic field probe (loop antenna) by simply connecting the RF output of the probe to an EMI receiver or spectrum analyzer. The built-in tone generator and speaker converts the field strength to a variable tone frequency, which is also useful for radio direction finding localization.
The magnetic field strength meter's built-in NiMH rechargeable battery provides 30 hours of run time. The optional automatic charger will fully recharge the battery, making it independent of its previous state. Test results can be directly converted to your desired units such as Tesla, A/m, etc. using the magnetic field strength conversion formula.
