Microbalance MYA 21/52.5Y

MYA 21/52.5Y: A High-Precision Microbalance Designed for Demanding Laboratory Environments

The Radwag MYA 21/52.5Y microbalance is a high-precision weighing instrument engineered to meet the strict requirements of scientific, pharmaceutical, chemical, and industrial laboratories. Featuring a dual weighing range—21 g with 1 µg readability and 52.5 g with 10 µg readability—it delivers maximum reliability even for ultra-light samples. Its technological core includes an automatic internal adjustment system combined with an optimized stabilization algorithm, ensuring a rapid response time of approximately 3.5 seconds.

This Class I balance, compliant with OIML standards, offers outstanding repeatability (up to 1.5 µg) and rigorous linearity (±10 µg in the lower range, ±30 µg in the higher range), making it an ideal choice for protocols that demand perfect traceability and long-term measurement consistency. Its versatility extends to complex operations such as statistical quality control, differential weighing, formulation, and air density correction.

A 10-inch color graphic touchscreen provides intuitive navigation through the balance's extensive functionalities. The automatic opening of the weighing chamber doors allows for contactless, precise sample handling, while the Reflex Level System ensures optimal leveling of the device at all times.

The MYA 21/52.5Y is equipped with a wide range of interfaces, including USB-A, USB-C, RS232, Ethernet, HDMI, Wi-Fi, and hotspot mode, enabling seamless integration with various software and peripheral systems. Its compact housing is delivered with essential accessories such as a terminal, glass draft shield, tweezers, brush, and fabric dust cover.

Designed to operate in ambient conditions ranging from 10 to 40 °C and 40 to 80% humidity, this microbalance easily adapts to environmental changes thanks to its excellent thermal and hygrometric stability.

Ideal for fine metrology applications, the MYA 21/52.5Y stands out for its consistent precision, ergonomic design, and extensive connectivity—making it indispensable for demanding professionals.
