Description
A&D Weighing® Microbalance, ION Series Model BM-20, 22 g x 0.001 mg, Internal Calibration
Features:
- Built-in integrated fan-less ionizer to prevent static which can cause errors
- Enhanced performance due SHS weighing technology
- High sensitivity with six decimal place microgram, readability 0.001 mg (1 μg)
- One-touch, full digital internal calibration with auto self-calibration (ASC) which allows balance to adjust for temperature variations, ensuring consistent measurements
- Dual draft rings to reduce draft interferences
- Standard RS232C allows for easy system integration
- Work efficiently, open either door from opposite side, or open both doors with one hand
- Large breeze chamber is flexible enough to adjust to all sample vessels small or large
Included:
- Gold coated pans (Ø50 mm and Ø95 mm) for weighing filters
- Aluminum pans 3 sizes (8, 12 & 15 mm diameter), disposable - 10 each
- AX-BM-032 microtube holder
- AD-1688 weighing data logger
- AD-1689 tweezers
- AX-BM-033 dust storage cover
