Enemy of Precision Weighing
Static electricity, while often overlooked, can be a fatal source of error in precise weight measurements. With the BM Series, A&D seek in various ways to help you perform sometimes-tricky analytical weighing with simplicity and accuracy, including the elimination of static electricity. The world of micro grams (ìg) is now accessible to all researchers!
Errors due to static electricity
An electrostatically charged object induces the opposite charge in nearby objects. The attraction between the two charges causes an inaccurate value.
1. Error when weighing a charged object
The value will be shifted in the positive direction. It then gradually changes as static electricity is discharged into the air or via the weighing pan.
2. Error when a charged object approaches
The value will be shifted in the negative direction. Static induction from a charged object like clothing (frequent in dry winters) can be a cause of a drifting value
Built-in Fanless Ionizer
The internal ionizer neutralizes an electrostatically charged object instantly. Simply hold the sample in the neutralizing chamber for a second before placing it in the weighing chamber
Direct-current (DC) method
The DC ionizer is fanless do you can even neutralize fine powders without having them blown away.
Long life of approximately 10,000 hours
The discharge electrode pins of the ionizer can be used continuously for approximately 10,000 hours and are safely replaceable
Anti-static Breeze Break
The thin evaporated metal coating of the breeze break blocks outside static electricity
Motor-driven Internal Calibration Mass
The internal mass of the BM Series allows you to perform calibration quickly and correctly even if you are not skilled at calibrating balances using external masses
Automatic Self Calibration
The balance can self-calibrate automatically when it detects a change in ambient temperature
One Touch Automatic Calibration
The accuracy of your balance is assured with one key press
Automatic Response Adjustment
The balance automaticlly adjusts its response characteristics (FAST, MID or SLOW) by analyzing the influence of drafts or vibrations on the stability of the display value.(Manual adjustment is also possible)
Special Pans and Holder
The BM-20 and the BM-22 includes three sizes (10 pieces each) of aluminum analytical pans, two pans for weighing PM filters, and a microfuge tube holder as standard you can allways call us here at scalesgalore.com form more information

Large Weighing Chamber for Improved Usability
To block drafts, A&D adopted a double-ring structure around the weighing pan and two vertical shields under the separation plate. This offers more space and easier operation than conventional 1 ìg balances with a secondary breeze break in the chamber
A large flask or cylinder can be weighed by removing the separation plate (for a resolution of 10 ìg or higher).
Clear, Reverse Backlit LCD
The contrast of black and white display provides excellent readability
Interlockable Sliding Doors
It is possible to slide a door open using the handle on the opposite side. Effective use or both hands lets you perform weighing more efficiently
The "door" sign is displayed until the two side doors are completely closed.)
Built-in Environmental Sensors
The balance displays the temperature, humidity and atmospheric pressure for users whe need to record thesr environmental conditions.
Twelve Weighing Units
You can easily select from g, mg oz,ozt, mom, dwt, GN, teal, tola, in addition to PC (counting mode) and % (percent mode)
Density Determination Function
For the BM-252/200/300/500 an optional density determination kit (AD-1653) is available here at scalesgalore.com for easy calculations of dendity
Data Memory Function
The balance can store up to 200 sets of weighing data(100 sets thith date and time) or 50 sets of calibration history data.
GLP/GMP/GCP/ISO Compliant Output
In accordance with the Good Laboratory Practice (GLP) the balance can output the balance manufacturer, model, serial number, ID number, date, time, calibration mass used, space for signature, etx.
Two Types of Interfaces – RS-232C and Quick USB(standard)
Two different devices (e.g. PC and remotr controller) can be connected simultaneously to a balance. An external key plug for the optional foot switch (AX-SW128) is also provided as standard
Weighing data transfer from the balance to a PC only. Please use the AX-USB-9P for two-way communication or GLP output via USB
LAN-Ethernet Interface (BM-08, optional) with WinCT-Plus Software
You can send commands for controlling and acquiring data multiple balances.
AD-1688 Weighing Data Logger (Standard Accessory)
The AD-1688 is a handheld device (55 x 103 16.5 mm) that stores up to 5000 weighing results with date and time. You can retrieve the saved data later by connectiong the AD-1688 to a USB port of your computer(no driver software is necessary)
