3321 Color Thermometer

The markings are clearly printed and easy to read, which matters when you're timing development steps. It reads accurately against my other thermometer, so I trust the readings during my process.

Swapped out my old thermometer for this one mid-batch and the readings stayed rock steady, which is exactly what I needed for consistent development. The build quality feels genuinely tank-like, like it’ll survive decades in the darkroom. My negatives have never come out this evenly processed.

It’s a bit pricey for a thermometer, but the precision and build quality are reassuring—the probe reads accurately to the tenth of a degree, which is exactly what I needed for consistent process control. The housing feels solid and the display is easy to read even in dim light.
