Whether for film or paper development, color or black and white - this thermometer measures precisely and reliably.
It has been specialy developed for the use in the darkroom with a narrow range of 50 to 120°F allowing a more accurate scale to be spread out over this narrow range.
Thus the large display can be read easily under red darkroom light, and if you're doing sheetfilm tray development in complete darkness, you'll love the glowing indicator and the marker at 20 degrees. The thermometer is made from rust-free stainless steel and is maintenance-free. If you drop it, the indicator will jump around like crazy, but it won't break like it's glass cousins. The included stainless steel clip helps make sure that the thermometer sits securely on the tray lip and that the scale is level.
