Paterson Certified Thermometer – 9″

I was tired of guessing temperatures in my darkroom, but this thermometer's dual Fahrenheit and Celsius scales make it foolproof. The 0.25°F steps are precise enough for consistent prints every time.

The 0.3°C increments on this thermometer make dialing in developer temps stupidly easy, and it reads true against my lab-grade probe. Feels solid in the tank too, no wobble. My negatives have never come out this consistent.

Finally got tired of guessing with my old thermometer and this one's a game changer. The dual scale is perfect for when I'm switching between metric and imperial recipes, and the 0.25°F steps give me real confidence my chemicals are spot on.
