My "MULTIMETER TS-352B/U" VOM. Old, analog, 20,000 ohm/V, 5,000 Volt multiplier. It's heavy enough to be used as a weapon. But it can go to the field, be used, abused and keep on working under conditions that my electronic VOMs would die in. I replaced the 4.5 V batteries with 3 cell AAA holders. Put in lithium AAA and it runs for years.
