Quick Verdict
Choosing between these two used lab balances starts with a single question: what will you put on the pan? The Citizen CX 220 is built for analytical work where small samples need fine resolution. The Mettler Toledo XSR1202S is a top-loading precision balance that moves quickly through larger, heavier weighing jobs. For sub-gram analytical tasks, the Citizen is the clear pick. If you need automatic calibration and a bigger pan for varied lab work, the Mettler makes the case for its higher price.
Comparison at a Glance
| Feature | Citizen CX 220 | Mettler Toledo XSR1202S |
|---|---|---|
| Listed Price | $699.99 | $1,999.00 |
| Capacity | 220 g | 1210 g |
| Readability | 0.1 mg (0.0001 g) | 0.01 g |
| Balance Type | Analytical with glass draft shield | Top loading |
| Condition | Used, tested and working | Used, professionally inspected and cleaned |
Where Each Balance Wins
The Citizen CX 220 wins on resolution. Its 0.1 mg readability lets you track changes as small as 0.0001 g, and the glass draft shield isolates the pan from air currents that can destabilize light samples. It is a true analytical balance for fine weighing.
The Mettler Toledo XSR1202S wins on capacity and convenience. It tops out at 1210 g, so it can weigh a full beaker or a hefty batch, and FACT automatic internal calibration removes the need for external calibration weights. The top-loading pan accepts containers of varying sizes without the fuss of an enclosure.
Product Notes
Citizen CX 220 Analytical Balance 220g x 0.1mg Precision Laboratory Scale
If your workflow revolves around tiny samples, the Citizen CX 220's 0.1 mg readability is the standout reason to choose it. The glass draft enclosure helps you hold a stable reading, and the listing confirms the unit powers on and zeros properly to 0.0000 g. That is exactly what you need from an analytical balance. The limitation is the 220 g capacity - you won't be able to weigh anything much heavier than a small flask. It's also a used instrument with cosmetic wear like light marks and dust, so expect a working lab tool rather than a pristine new device. For analytical weighing of sub-gram quantities, this balance delivers where it counts.
Mettler Toledo XSR1202S Precision Balance (1210 g / 0.01 g
The Mettler Toledo XSR1202S earns its place with a 1210 g capacity that suits heavier lab work. FACT automatic internal calibration is a significant convenience, as it keeps the balance accurate without manual adjustment. The unit is described as professionally inspected, thoroughly cleaned, and in exceptional working condition, which adds confidence when buying used. The trade-off is readability: 0.01 g is coarser than the Citizen's 0.1 mg, so this is not the tool for milligram-level measurements. If you need a precise top loader for everyday weighing up to 1.2 kg, the Mettler offers range and automatic calibration in one package.
Final Choice by Use Case
For a biological laboratory that weighs reagents, enzymes, or micro-tubes in the milligram range, the Citizen CX 220 is the right type of balance. Its analytical resolution is the deciding factor.
For a lab that weighs larger batches, checks gross weights, or wants a top loader that calibrates itself, the Mettler Toledo XSR1202S is the better fit. Its wider capacity makes it a versatile daily driver.
