The Beseler Audible/Repeating Timer is an economical and reliable tool for the everyday darkroom. Its durable metal construction protects it from abuse while the heavy duty dual control knobs make time setting easy.
The internal metronome "beeps" once a second or can be turned off. It has a "10x" switch which allows rapid transition between full and tenths of seconds.
This timer, containing two grounded AC outlets, will automatically turn the safelight off during exposure and turn it on when the cycle is completed.
