A&D GF-300P 310 g x 0.001 g NTEP Precision Pharmacy Balance

Specifically designed for pharmacy use, the GF-P is ideal for pill counting and compounding. It meets the rigorous standards set forth by the National Institute of Standards and Technology Handbook 44 for a "Class A" prescription balance. The pill counting feature also complies with Handbook 44 requirements. NTEP certification assures legal-for-trade status in all states. Add all of that to the fact that it embodies the same great features as the standard GF series including super fast one second response time, and you've got a great pharmacy balance.

A&D combined two separate technologies to create the revolutionary Super Hybrid Sensor (SHS), which is the cornerstone of these user-friendly balances. The unique design produces ultra fast one second response speed, increased accuracy and reduced maintenance costs. The increased speed and accuracy make it ideal for feeding/batching applications or filling machine installations.

Accuracy is enhanced through reduction of temperature-induced drift. Should repairs be necessary, the damaged part can be isolated and replaced without replacing the entire sensor.

GF models utilize external calibration (masses sold separately). GX balances feature One-Touch Automatic Calibration for internal calibration and Automatic Self-Calibration to respond to ambient temperature changes.
