Digital scales
by On Balance
We'll only email you about this product — no marketing.
The On Balance Myco is a pocket-sized digital scale that measures up to 100g in 0.01g increments — accurate enough to weigh out small quantities with genuine precision. At just 9.3 x 5.3 x 1.6cm and 50g with batteries, it's smaller than most smartphones and lighter than a pack of cards. If you need reliable 0.01g accuracy without lugging around a bench-top unit, this is the one to grab.

Need to measure below 0.01g? The On Balance CK-20 Digital Milligram Scale reads down to 0.001g for ultra-fine weighing. If you need more capacity but still want 0.01g precision, the On Balance TW-200 TruWeigh handles up to 200g. Both pair well with the Myco if you want a travel scale and a home scale without doubling up on the same specs.
An ordinary kitchen scale reads to 1g at best. That's fine for flour, useless for anything where a tenth of a gram matters. As any experienced weigher knows, an ordinary kitchen scale that can only measure to a precision of 1 gram won't cut it when you need accuracy down to 0.01g. The Myco fills that gap without the bulk or the price tag of a lab balance.
We've handled dozens of mini scales over the years, and the thing that separates a decent one from a frustrating one is consistency. You put the same 5g weight on three times, you should get 5.00g three times. The Myco does this reliably straight out of the box, and if you ever doubt it, the Mode/Cal button lets you recalibrate with a known weight. That 10-year warranty from On Balance isn't just a marketing number — they've been making scales long enough to stand behind them.
The honest limitation: the 5.5 x 4.9cm platform is small. If you're weighing anything bulky, you'll want to use the clear plastic case as a tray (it doubles as one) or place a small container on the platform and tare it out. For anything over 100g, you'll need a bigger unit entirely. But for precise, portable weighing under 100g, the Myco is the best pocket scale we carry for the money.
Three buttons. No menus. Here's how it works:
The Myco genuinely disappears in a jacket pocket. At 50g it weighs less than an egg, and the case adds barely any bulk — the whole package is about the size of a Zippo lighter, maybe a touch wider. The plastic case has a satisfying snap closure and the buttons have a firm click rather than a mushy press. The backlit display is bright enough to read in dim conditions without being blinding. It feels like a tool, not a toy — which is exactly what you want when you're relying on 0.01g accuracy.
| Feature | On Balance Myco | Typical budget pocket scale |
|---|---|---|
| Capacity | 100g | 100-500g |
| Readability | 0.01g | 0.1g |
| Weight | 50g | 80-150g |
| Dimensions | 9.3 x 5.3 x 1.6cm | 12 x 7 x 2cm+ |
| Calibration function | Yes (Mode/Cal button) | Often missing |
| Warranty | 10 years | 1 year or none |
| Batteries included | Yes (2 x AAA) | Sometimes |
The key difference is the 0.01g readability. Most cheap pocket scales only resolve to 0.1g — that's a tenfold difference in precision. If you're measuring anything where tenths of a gram matter, the Myco is worth the step up. The trade-off is the 100g cap: if you regularly weigh amounts over 100g, look at the On Balance TW-200 TruWeigh instead.
The Myco reads to 0.01g increments across its full 100g range. On a flat surface with fresh batteries, it's consistently accurate. You can verify and recalibrate it anytime using the built-in Mode/Cal function and a known reference weight.
Two AAA batteries, both included in the box. AAAs are available everywhere, so you won't be stuck with some obscure button cell when they run out. Battery life is solid for a scale this size — we've seen them last months with regular use.
Yes, that's exactly what it's designed for. Place the clear case on the platform, press Tare to zero it out, and add your material. It keeps small items contained and protects the platform from spills.
Hold the Mode/Cal button for a few seconds until the display shows a calibration prompt. Place a known calibration weight (ideally 100g) on the platform and confirm. The manual walks you through it step by step. Worth doing every couple of months or if readings seem off.
For anything requiring 0.01g precision, 100g is plenty — you rarely need milligram-level accuracy on large quantities. If you regularly weigh over 100g, pair the Myco with a larger capacity scale like the On Balance TW-200 for the best of both worlds.
It cycles through grams (g), ounces (oz), troy ounces (ozt), pennyweights (dwt), and carats (ct). Press Mode/Cal briefly to switch between them. Most people stick with grams, but the options are there if you need them.
Yes, the Myco powers down automatically after a period of inactivity. This keeps battery drain minimal — handy when you're using it on the go and might forget to switch it off manually.
