Schwarzbeck HMDA 1545 Handheld Magnetic Field Meter

Unlike low sensitivity passive meters, this active meter with alower detection threshold of<46 dBμA/m (200μA/m) operates also in the range oflow field-strength. In the insensitive range magnetic field- strength up to more than 120 dBμA/m ( 1 A/m) iscovered. When many strong signals are present, or frequencies are of interest, the HMDA1545 can be used as anactive magnetic probe (loop antenna). Just connect the r.f.-output to a receiver or spectrum analyser. The built-in tone generator and loud speaker convert field-strength into variable tone frequency. This is very useful for radio direction finding with final reading of the 3 1/2digit LCD. The full metal cabinet and the electrically shielded antenna are very rugged. Operation via 3 toggle-switches is very easy. The built-in NiMH rechargeable battery gives 30 hours of operation. The optional Automatic Charger will perfectly charge the battery independent of its previous state.
