Radwag scales

Buying guide

Choosing a Radwag scale

Start by fixing the finest division you actually require, because that single number decides which Radwag family you are shopping and sets the floor on price. An assay that needs 0.1 mg readability points at the AS analytical balances; a sample weighed to the microgram pushes you into the XA or MYA microbalances and the handling overhead they bring; bulk preparation or goods weighing sits with the PS, WLC or platform instruments. Do not over-specify: a balance resolving finer than your method can use costs more and takes longer to settle.

On a used Radwag unit, three things decide whether the listed readability is still real. Check that internal adjustment works and that the balance holds calibration against a reference weight of the appropriate OIML class, since a drifting load cell cannot be cheaply restored. Inspect the weighing pan, draught shield and levelling feet, as a bent pan or a cracked shield on a microbalance undermines the rated figure. Ask the seller for a recent calibration record or test report; a unit sold without one may still be good, but you are buying the readability on trust. With 15 used listings against 1670 new, the used pool is small, so the choice is often new by default rather than by preference.

On compatibility, the main trap is the terminal-and-platform split: Radwag platform scales and weighing terminals are sold as matched pairs, and a terminal is not freely interchangeable across platforms or capacities. Confirm the terminal and base are specified together before buying either alone. For laboratory balances, check that the draught shield, pan and any anti-vibration accessory match the specific series, as parts do not carry across the XA, MYA and AS families despite the overlapping naming. Where you need a replacement part or documentation, parts can be sourced via Questpair.

Which Radwag balance and scale series are listed here?

Among the listings that specify a type, the intersection splits into two worlds: laboratory balances on one side and industrial and platform weighing on the other, with weighing terminals bridging them. The laboratory end carries the XA series, which spans analytical balances and microbalances, alongside the MYA microbalances and the UYA ultra-microbalances for the lightest loads. The AS series covers conventional analytical work, while the PS and WLC series handle precision balance duty where milligram readability is enough. For production and goods-in, the platform scales and industrial scales pair a stainless weighing surface with a separate weighing terminal, which is why "weighing terminal" appears as its own type rather than folded into the scale. Moisture analysis sits apart again: the MA series dries and weighs in one cycle to report water content, so it belongs with the balances by precision but with the process instruments by purpose. Use the series name as your filter, since a single listing word like "precision balance" can cover both a PS and a WLC.

Where the series diverge on readability and capacity

The deciding specification across this range is readability against capacity, and Radwag's own families sort cleanly along it. The UYA ultra-microbalances resolve to the tenth of a microgram over a small capacity, the MYA and XA microbalances to the microgram, and both demand a draught shield and a stable pier to reach their rated figure. Step up in capacity and the AS analytical balances settle at 0.1 mg readability with capacities in the low hundreds of grams, which suits general gravimetric analysis without the handling discipline a microbalance needs. The PS and WLC precision balances trade resolution for range, reading to the milligram or ten-milligram over capacities from several hundred grams into the kilograms, so they carry sample preparation and bulk weighing rather than assay work. At the industrial end, platform scales abandon sub-gram resolution entirely for capacities measured in tens or hundreds of kilograms. The practical rule is that readability and capacity trade against each other, so match the finest division you genuinely need rather than the finest the family offers, since a microbalance on a loading dock is wasted and an analytical sample on a platform scale is unreadable.

How price and condition break down

Prices span from EUR 18 to EUR 156.663, with an average around EUR 4.714. That spread tracks the readability ladder above: the floor sits with simple bench and platform units, the ceiling with ultra-microbalances and fully equipped laboratory systems, and the average lands nearer the precision-balance band where most catalogue volume sits. The condition mix is weighted heavily toward new stock. 1 percent of the listings are used.
