Paterson Certified Thermometer - 9"

The dual scales on the stem make it easy to read regardless of which side I’m looking at, and the 9-inch length keeps my fingers clear of the chemistry. Steady readings right out of the box, no fiddly calibration needed.

The 0.3°C accuracy gave me real confidence dialing in my developer temperature for the first time. The 9" glass stem is long enough to read easily without leaning over the tank. A simple, reliable tool that does exactly what it should.

The dual scale markings make it easy to read Celsius and Fahrenheit without squinting, and the 0.3°C accuracy gives me confidence my developer is spot on. It feels sturdy for a glass thermometer, too.
