Timbangan Micro balance AND HR-250A

HR-250A Analytical Balance 

The HR-250A Analytical Balance is a high-precision, standard-level laboratory instrument designed for accurate and efficient weighing tasks up to 252 grams with a readability of 0.1 milligram. Equipped with A&D’s innovative Compact Super Hybrid Sensor (C-SHS), this model ensures ultra-fast stabilization in just 2 seconds while maintaining a compact footprint—ideal for labs and industrial environments where space and speed are critical.

Designed with simplicity and durability in mind, the HR-250A is an excellent entry-level analytical balance for routine measurements in research, education, and quality control. Its detachable breeze break simplifies cleaning of the stainless steel weighing pan, spill ring, and base, supporting contamination-free operation and long-term maintenance.
