Sebastian J. ★★★★★ Oct 23, 2026

The markings are clear and easy to read, which is a relief when I'm fumbling around in dim red light. It's long enough to reach into a deep graduate without my fingers touching the chemistry.

Emma U. ★★★★★ Oct 22, 2026

The 9-inch size is perfect for reaching into tall graduates without burning my fingers on the tank. Readings are consistently accurate from 60°F right up to 85°F, which covers all my B&W chemistry needs.

Thomas ★★★★★ Oct 20, 2026

I was worried the markings would be hard to read in dim light, but the red liquid and clear scale are actually very visible. It’s a solid, simple tool that reads accurately across the 56-86°F range. Exactly what I needed for my developing tray.
