The General Electric Type PR-1 Exposure Meter, often marketed as the "meter with a memory," is an analog light meter first introduced in 1947. It was a significant departure from GE's earlier, simpler designs, featuring a compact, palm-sized body made of Bakelite.
Key Features:
- Needle Lock: A standout feature that allows you to take a reading, release a side button to lock the needle in place, and then read the settings at your convenience.
- Trident Analyzer: A triple-pronged indicator on the calculator dial. The center tine represents the direct reading, while the side tines indicate ±1 stop, facilitating easy bracketing.
- Selenium Cell: It is self-powered by a selenium photo cell, meaning it does not require batteries to operate.
- Automatic High/Low Ranges: The meter covers two light sensitivity ranges (High and Low) that switch mechanically as you rotate the outer dial.
