The Apollo GX Series Precision Balance from A&D Weighing combines state-of-the-art functionality with remarkable speed and precision. Designed for laboratories and quality control settings that demand reliability, this balance features an Electronically Controlled Load (ECL) self-check system that performs internal repeatability tests without external weights in under 1.5 minutes.
Equipped with Super Hybrid Sensor (SHS) technology, the GX Series delivers accurate results with 1-second stabilization time and enhanced repeatability. The system includes internal calibration weights and a fanless ionizer on AE versions, making it ideal for clean environments or samples sensitive to electrostatic interference.
With a broad range of operating modes—including animal weighing, density determination, statistical calculation, and ACAI counting—the GX Series adapts seamlessly to complex weighing tasks. The unit also provides robust connectivity via RS-232, supports GLP/GMP/ISO data transmission, and ensures security with password protection and anti-theft slot.
