The ATTO LABWARE Analytical Balance models KAB 224 and KAB 324 are high-precision instruments designed for accurate laboratory measurements. The KAB 224 model offers a maximum capacity of 220 grams, while the KAB 324 model extends this to 320 grams. Both models feature a 90 mm diameter stainless steel pan and utilize motorized internal calibration, ensuring reliable and consistent performance without the need for external weights.

These balances offer exceptional precision, with a readability of ±0.0001 grams (0.1 mg) and repeatability of ±0.0001 grams. The linearity is rated at ±0.0002 grams, providing highly accurate results for analytical applications. The minimum measurable capacity is 0.01 grams, making the devices suitable for a wide range of scientific and laboratory tasks.

The balance is equipped with a white backlit LCD display for clear visibility in various lighting conditions. It delivers quick results, with a response time of under 4 to 5 seconds. A full-range tare function is supported, and the device operates reliably within a temperature range of 15°C to 30°C.

Both models support density measurement and include multiple weighing units such as grams (g), milligrams (mg), carats (ct), ounces troy (ozt), ounces (oz), grains (GN), pennyweights (dwt), and pounds (lb). They are equipped with an RS232C interface for seamless data communication with computers and printers, and support command and continuous data output modes.

The balances are powered by AC 220V / 50–60 Hz and have a compact design with dimensions of 220 x 360 x 345 mm. Each unit weighs approximately 10 kilograms, making them sturdy yet manageable for laboratory bench use.
