Digital Scales

I have been researching digital scales and I would appreciate some feedback on this scale. I know it is only a 300g capacity and there may be a BIG problem for leaking. Is this overkill for the purpose of MMS/MMS2/CDS making?



Or maybe this?

I would appreciate some feedback/opinions

Thanks!

I would go with something with more capacity. I bought a 500 gram scale and find I have to do more frequent smaller batches because I can't double the mixes. Also go for one that can have it's auto-off function turned off - it's a learning curve to operate faster than the auto-off.

I don't have any experience with the one you're showing - but he's having to pick up a tool to operate the controls - that would be a pain .

Just an update...

I purchased the Jennings CJ-600(new) for what I consider a low price from the on line bidding site. This is a link summary from a vendor, I will post results when used.

Two things I notice.. You will be making small batches of MMS - 600g is not a lot of weight, when you have the container also to weigh. I have a 1 quart glass saucepan that I use, and it weighs more than 600 grams, itself. The second is that I could not determine if there is an auto-off feature that can be enabled/disabled. This is crucial, IMHO.

Have fun, let us know how it turns out.

There is a fine line between finances and desirability. The higher weight capacity machines(4000g) have a +/- tolerance of 1-2 grams(which I understand is not recommended) while a higher quality machine with tighter tolerance are much more expensive. I understand the concern with the low weight limit...but I should be able to circumnavigate the problem in hopefully one of two ways. The water could be either...(A). Weighed piece meal until the correct weight is reached or ( Not weighed but measured by volume via a measuring cup as water should have a known weight. The on/off feature is three minute limit but this unit has an optional 6-volt ac adapter that should disable the on/off timer(hopefully).

I know about "the best made plans of mice and men" but this is my thinking, or lack thereof depending on your point of view and or experience level. What do ya think?

I didn't put the smiley face on my reply...not sure how it came to be.

Sometimes all we can do is experiment! I say, go for it.

What I have found, in my experience, is that where the container being weighed sits on the platform will cause the weight to shift. When I start to make, I keep the container on the platform through the whole operation, as I've found that taking it off and putting it back is where I get a difference in weight.

Pam...I searched and came up with this...what do you think?

Of course...the piece meal method will also be in effect till confirmation.

This is a nice chart. Steve is the expert, he has a great chart on his website for measures and weights, too. keavyscorner.com/index.php?main_page=page&id=8&chapter=10


As I look at it, say you wanted to use a pint of water, you would get the weight of that, 471.8g and multiply that by 28%, which is 132.1g.

You would tare out a small glass container and measure out 132.1g of water, from your pint and set that aside.

Take another small glass container, tare it out and measure 132.1g of SC into it.

Then combine the water (which now is less than a pint) and the 132.1g of SC.

Ok it late....so excuse my slow thinking. I measure water(weight) to mix with sodium chlorite. I find the volume of water in fluid ounces that I can measure in a standard measuring cup that will be converted to grams so I can use the scale you offered earlier.
