Small B/W Thermometer Without Mercury is a darkroom thermometer for controlling solution temperature. The card is based on the current manufacturer and supplier specifications, without unverified review claims.

Best uses

It is intended for a controlled analogue workflow at home or in a small lab. Match its dimensions and working range to your film format and processing setup before ordering.

Practical notes

I recommend checking the item immediately after delivery and keeping it clean and dry between sessions. For precision tools, compare the reading with a known reference before critical processing.
