Paterson Certified Thermometer - 9" PTP363

The dual scale in both Celsius and Fahrenheit is really handy for mixing different recipes. The 0.3°C steps give me the precision I need for consistent development times. Feels solid and accurate.

The markings are crisp and easy to read even in dim darkroom light, and the 0.3°C increments give me the precision I need for consistent film development. It's a solid, reliable tool that does exactly what it's supposed to.

The dual scale is what sold me, and the 0.3°C increments from 13 to 30°C are perfect for my C-41 chemistry. Readings settle fast and match my reference lab thermometer almost exactly.
