Review on Traceable Four Channel Alarm Timer by Control Company 5004 by Ian Hallford

We use this timer to stain our hands in the histology laboratory. We use all 4 channels and this saves us from running too many separate timers at the same time. Very reliable, very easy battery change! They last quite a long time. We normally tape the front of the timers with clear tape to prevent stains and acids from damaging the screen - and this doesn't affect the use or operation of the timers in the slightest! We also go directly to the buttons. Works like a dream!
