Class III (calibration optional); medical approval according to 93/42/EEC; mobile design with particularly comfortable locking brakes on all four wheels. With its four wheels, this chair scale ensures maximum mobility when transporting patients. This results in greater time efficiency for clinical staff and improved safety for patients, who can be weighed in their familiar environment. The four swivel casters, with their large cross-section, facilitate easy navigation over door thresholds, edges, and gaps in passenger elevators. This chair scale is the ideal measuring instrument for elderly care and paramedicine, including weighing in the obese range up to 300 kg. For frail patients, the comfortable, ergonomically optimized seat shell provides secure support during weighing. Two foldable armrests and footrests make it easier to take a seat. Ideal for overweight patients or for barrier-free transfers, e.g., from the bed to the chair scale. Hold function: For patients who are restless, a stable weight value is determined through averaging and "frozen." This allows sufficient time to attend to the patient and then calmly read the weight value. BMI function to determine underweight, normal weight, and overweight. Ergonomic display device with a large keypad and high-contrast LCD display for easy input and reading of patient values, such as height for BMI calculation. Battery and mains operation possible, with battery operation optional. Protective cover included in delivery.
