OHAUS PR523 Semi-Analytical Balance 520 g / 0.001 g (Internal Calibration)

OHAUS PR523 is a semi-analytical balance developed for routine weighing operations in laboratory, industrial, and educational settings. It delivers 520 g capacity with 0.001 g (1 mg) readability, combining accuracy with ease of operation.

The instrument is offered in two configurations: PR523 with internal automatic calibration or PR523/E with manual calibration, providing flexible options for different budgets and verification requirements. The 3-sash design windshield reduces weighing deviations caused by air currents, while the 2-second response time enables fast result acquisition. Adjustable stabilization settings allow adaptation to varying environmental conditions.

Repeatability is specified at 0.001 g and linearity at 0.002 g; according to USP standards, minimum load (%0.1, k=2) is 2 g. Operating temperature range of 10-30°C provides stable performance with sensitivity drift of ±3.0 ppm/K. Wide voltage support of 100-240V ensures seamless operation across different electrical infrastructure.
