مقياس حرارة خزان تحميض Kaiser - بلاستيك

The plastic stem gives me peace of mind when I accidentally knock it against the tank, and the alcohol column responds quickly to bath temperature changes.

I was tired of worrying about glass thermometers breaking in my darkroom, so the plastic stem on this one is a relief. The scale is clear and easy to read even in dim safelight, and it seems to give accurate readings for my developer.

Finally stopped knocking my glass lab thermometer over in the darkroom. The alcohol column is easy to read against the -10 to 50 scale, and the plastic stem feels solid enough to leave in the tank between agitations. Doing its job without fuss.
