Purchasing a Gram Scale

[stevenje]

I am looking to buy a gram scale for the darkroom. Any recommendations on which one to buy?
Thanks in advance.

There are a ton to choose from. You first need to decide what the maximum weight you will ever need to weigh. The smaller the less expensive. Then decide how fine a measurement you want -- 1gr, 0.1gr, 0.01gr, etc. The finer the more expensive. Then do you want digital or analog. You can get a lot of great USED analog scales for next to nothing because everyone wants digital. But analog never needs batteries.

I use an Ohaus CENT-O-GRAM. Up to 311 grams (11 ounces), and measures to 0.01 gr.

I wanted a small portable scale so I did not have to drag my AC powered lab-grade digital balance to a workshop I was teaching.

Thus. I bought this one... https://www.amazon.com/dp/B07DJBDL6L a month ago. 500 g capacity , 0.01 g resolution which is good enough for most alt process work.

It got a heavy workout during the day long workshop without a hitch.

The old Ohaus "high-school science " mechanical balances work great. Nothing with springs. The Ohaus Harvard Trip balance is terrific for mixing powders. A small electronic scale for tiny amounts comes in handy. I bet I have a dozen different balances.

I assume your purpose is to weigh out bulk chemicals to prepare processing formulas. I've done this for more than 40 years, using a traditional Ohaus Triple-Beam Balance scale. This scale resolves to 0.1 gram, and is completely adequate for any photo formula. Modern digital technology gives us small platform scales for around $20, which resolve the same and work bout as well. They are cheaper and easier to use. Available on-line or in any office supply store (postal scale). No photo process requires more precision or expense.

I use one with a maximum capacity of 300g and a read-out resolution of 0.01 g. Unfortunately, it is just labeled as 'Digital Scale.' it was inexpensive and works great. 300 g is about the maximum quantity you need in a small darkroom. I bought another with a max of10g and a resolution of 0.001 g, which I need for a few chemicals, of which one only needs trace amounts. Both are available from Amazon.

Remember. Resolution is not the same as accuracy.

There are many cheap digital scales out there that display to 0.01g but whose accuracy is around +/- 0.1 gram

Remember, make it as complicated as possible!

A $15 Cen-tech pocket scale from Harbor Freight has worked fine for me for several years. Accurate to 0.1g, which is close enough for anything I’m mixing in the darkroom.
