The Radwag PS 1000.R1 Precision Milligram Balance has a capacity of 1,000g, a readability of 1mg (0.001g), a 128 x 128mm (W x D) stainless steel weighing pan, a control panel with programmable function keys and an LCD, internal memory for storing profiles and measurements, a draft shield, and 11 built-in applications for advanced lab weighing tasks. (W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The control panel has an LCD with a text information line that shows messages and data, and a backlight for visibility. This balance has two RS-232 ports, a USB-A port, and a USB-B port for connecting to a computer, printer, or other peripheral device (sold separately) to output data or monitor balance functions. It has internal memory for storing up to 10 user profiles, 1,000 product profiles, 5,000 weight measurements, and 100 tares, plus alibi memory storage of up to 100,000 consecutive measurements. The balance has a draft shield to help ensure accuracy, and can be calibrated using external weights. A weighing port allows underfloor weighing of oversize containers. Leveling is performed by manually adjusting the feet until the air bubble is properly centered in the level indicator. The balance comes with a 120V power adapter. A precision toploading balance is used in laboratories and other indoor settings for determining the mass of a liquid, paste, powder, or solid sample.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Balances and scales are measuring instruments used to determine the mass and weight, respectively, of an object. Unlike a balance, a scale's accuracy is affected by gravity and must be recalibrated if it is relocated. In practice, the terms balance and scale are frequently used interchangeably, and the results are displayed in a variety of units, such as gram (g), ounce (oz), pound (lb), troy ounce (ozt), pennyweight (dwt), carat (ct), momme (mom), grain (GN), and tael (tl). The empty weight of a container used to hold objects (tare weight) on the balance or scale is removed prior to weighing, so that the scale reads zero with the container in place. The precision of both balances and scales is determined by the requirements of their intended use, and can be 0.0001g or better for analytical balances. Precision is verified and maintained with periodic calibration. For commercial use, scales and balances may be certified by organizations such as NSF International and National Type Evaluation Program (NTEP). Balances and scales may include data interfaces that allow connection to a computer, printer, or remote display. Balances and scales are made suitable for the environment in which they are used with protective housings, sealed keypads, and lighted displays. They may have built-in functions for tasks such as pill counting in pharmaceutical applications, postage calculations in shipping applications, or weight-totaling in warehouse applications. Balances and scales are used in a wide variety of applications and accommodate a wide range of weights.

Radwag manufactures balances, scales, weighing systems and software, and other weighing equipment. The company, founded in 1984 and headquartered in Radom, Poland, is ISO 9001:2008 certified.
