Finally a thermometer I can trust in the darkroom. The 0.3°C accuracy gives me real peace of mind when I'm mixing chemicals, and the 9" stem reaches deep enough into my jug without splashing. Readings are steady and easy to catch at a glance.

The dual scale markings are a lifesaver—I can read Celsius or Fahrenheit without squinting, and the 0.3°C accuracy gives me real confidence when developing at 20°C. The 9" glass stem reaches deep into my chemistry bottle without me burning my fingers. Worth every penny for consistent rolls.
