AIR MINISTRY OHM METER, 1932
Air Ministry meter for measuring Ohms from .01 to 0.1 with power connection on the back for a battery and four terminals giving different ranges. It is dated 1932
Your comments:
- My own similar Record Ohmmeter is the civilian version of the one illustrated and is operated with a 1.5 volt internal battery. It is also housed in a wooden box and has two ranges 0-5 Ohms and 0-50 Ohms. It is very well calibrated and reads low resistances down to 0.01 Ohm. The man behind Record meters was Mr Jack Record of Altrincham near Manchester and he was responsible for one or two noted innovations in meter design from about 1922.
