Recommendations for fine accuracy scale

I'd like to start mixing some frankenpolish, and need recommendations for a scale to weigh my ingredients. I'm hoping for something inexpensive, and it does not need to weigh items that are heavier than 2-5 pounds. I have a kitchen scale that does not register small amounts. It needs to be sensitive enough to measure very small amounts of pigment and mica.

    The cheapest lab scale you can find will be fine.

    If you need more precision than that I suggest you use 2 scales, high precision and wide range are very expensive.

    So, if I simply search for a "lab scale" that is capable of approx 3000g/0.01g precision, do you think I'll be ok?



  • If you're doing color, especially in smaller batches, I'd go for one with 0.001 precision
  • A 3Kg scale with 0.01g precision would be very expensive and also, would likely need to be in a glass case to achieve that level of accuracy.
    It is percentage level accuracy that we need. If you are making, eg a 10Kg batch, than a scale accurate to 1 gram gives 0.01% accuracy which is quite enough.
    Look for a 3Kg scale with accuracy of at least 0.2g; there are a few around with accuracy of 0.1g ... it is easier to find a 2Kg scale with 0.1g accuracy.
    For tiny amounts - usually pigments - you can find little scales with very good accuracy on EBay, being sold for jewellery purposes. Two scales are much better than one.

    Agree with Belassi, accurate scales that can handle higher weights are expensive.
    I've got three scales (I make small batches btw):
    - 0,001 gram, max weight 50 grams (about 30 dollars);
    - 0,01 gram, max weight 200 grams (about 5 dollars);
    - 0,1 gram, max weight 1 kilogram (about 5 dollars).
    I've got these from AliExpress, they can be calibrated and as you can see they're extremely cheap! The most accurate scale can also be levelled and has 'airflow protection' (a housing around the weighing platform to minimize changes due to airflow).

    Keep the weight of the medium you will tare in mind (e.g. weighing paper or glass beaker etc), so you won't exceed the max of the scale (to prevent damage to mechanism).

    Excellent advice - I have broken a scale by forgetting that.
