Product Description
The Internal Calibration Analytical Balance models YR05568 to YR05572 are exemplary pieces of laboratory equipment that promise both precision and reliability for a variety of scientific applications. Designed to streamline the weighing process, these balances are equipped with both internal and external calibration capabilities, ensuring accuracy is maintained at all times. The models vary in capacity, with the YR05568 accommodating up to 220 grams and the YR05572 supporting weights as heavy as 610 grams, all with an impressive resolution of 0.1 mg. This level of precision is complemented by a minimum weighing capability of 0.4 mg, ensuring that even the smallest samples can be measured with confidence.
These analytical balances boast a stable time of ≤4 seconds, facilitated by an intuitive LCD display with a white backlight and black font for easy reading. Operation within temperatures of 5-35℃ is optimal, aligned with the robust design and an efficient draft shield size of 162mm×171mm×225mm, which minimizes the impact of environmental variables. An RS232C interface, with optional RS485 and printer connectivity, enhances data recording and transfer capabilities. With a net weight of 7 kg and dimensions of 345×215×345mm, these instruments are compact yet powerful tools in any laboratory setting.
