Solid tool, slightly slow response

Great build quality and the etched numbers won't fade like printed ones. It takes about 20 seconds to stabilize rather than the advertised 15, but once it does, it's very accurate. Good value for the price.

Best upgrade for my workflow

Switched from a plastic thermometer and the difference in stability is night and day. The metal conducts heat well for fast readings. It's become an essential part of my weekend developing routine.

Excellent precision

I tested this against a calibrated digital probe and it was spot on. The long stem allows me to measure deep in my processing tanks without getting my hands wet. A staple in my chemistry kit now.

Perfect for my darkroom setup

This thermometer is exactly what I needed for developing Ilford HP5. The readings are quick and the dual scale makes it easy to switch between recipes. The metal build feels very durable compared to my old glass one.

Good, but markings could be larger

The thermometer works great and is very sturdy. My only complaint is that the degree markings are a bit small if you have poor lighting in your darkroom. Otherwise, it performs perfectly.

No more guessing temperatures

Consistency is key in film development, and this gauge delivers. I love that it's all metal so I don't have to worry about breaking it in the tank. Highly recommend for beginners and pros alike.

5 FAQ

Q: Can I use this for color film processing (C-41)?

A: While physically capable of measuring the temperature, C-41 processing often requires higher precision (within 0.25°F). This thermometer has an accuracy of +/- 0.5°C, so it is primarily optimized for B&W processing where tolerances are slightly more forgiving.

Q: Are the temperature markings engraved or printed?

A: The markings are laser-etched directly into the metal surface. This ensures they will not rub off or fade over time, even with frequent cleaning and chemical exposure.

Q: Is this thermometer safe to leave submerged in developer chemicals for long periods?

A: Yes, the stainless steel construction is resistant to standard black and white developing chemicals, fixers, and stop baths. However, we recommend rinsing it with water after each use to maintain longevity.

Q: What is the length of the probe section specifically?

A: The total length of the thermometer is 20 cm. The probe section, which is the part intended for submersion, accounts for approximately 12 cm of that length.

Q: Does this come with a protective case for storage?

A: No, this item does not include a protective case. It is shipped in standard recyclable packaging. Many users store it in their existing chemical kits or purchase a separate tube protector.
