Features
The MC-A and MC-M series mass comparators deliver significantly improved precision and stability over the previous generation, enabling reliable comparison of reference weights in calibration labs—whether in-house or service-based. Despite the performance upgrades, the series remain cost-effective, making high-end mass comparison accessible to a broader range of users.
Smart tools for confident mass comparison
Auto-centering pan to ensure consistent accuracy
One of the challenges in high-precision mass comparison is eccentricity error caused by off-center loading, which can compromise repeatability and overall measurement accuracy. The optional auto-centering pan addresses this by automatically bringing the mass to the center of the balance. Its dome-shaped bottom rests on three ball-tipped supports, allowing smooth movement to correct eccentricity errors. If an automatic loading system is not used, A&D strongly recommends this option for manual loading
Stable weighing through control of external disturbances
Mass comparators, due to their extremely high sensitivity, are more susceptible to various external disturbances. To help the MC-A and MC-M series fully demonstrate their true capabilities, A&D also recommends the following optional accessories
- Remote controller (AD-8922A) - Operate the balance without direct contact, reducing vibration caused by manual handling.
- Tabletop breeze breaks (AD-1676 or AD-1672(A)*1) - Shield the balance from drafts and minor temperature changes caused by air conditioning or operator movement. Made of antistatic panels to minimize static effects.
Extra decimal place for system integration and fine control
The MC-A and MC-M series offer extended resolution not typically available in balances of similar capacity. This extra decimal place enables accurate tracking of small weight changes—even with heavy tare weights common in automated systems for precise dosing, blending, and other demanding processes.
Impact shock detection (ISD) for reliable automation - The ISD function detects impact loads on the weight sensor and displays their intensity in five levels (0–4). High-impact events (Levels 3 and 4) also trigger an audible alert and are logged for review, supporting system adjustments to prevent future errors and sensor damage.

AND Weighing AD-8541-PC Bluetooth Wireless Communication Interface for PC
The AD-8541-PC enables a PC (with communication software such as WinCT installed) to
wirelessly receive data from and send commands to the SJ-WP-BT series through its USB
port.*7
The commands available with the SJ-WP-BT series include read/set comparator
limit values as well as request data, zero, tare, clear tare, and switch the weighing unit so
that you can avoid troublesome key operation with the scale when confirming and/or
changing the comparator limit values.
*7 The driver software for the AD-8541-PC is automatically installed with Windows 8.1 or
later. If the driver cannot be installed, download it from the [Support] - [Software]
section of the A&D website (www.aandd.jp), where WinCT is also downloadable for free

AND Weighing AD-1684A Electrostatic Field Meter
The AD-1684A is an electrostatic fieldmeter designed for detecting the existence of static electricity, which is often the cause of inaccurate weighing.
The AD-1684A can be used for measuring the electrostatic charge of measured objects or on automated factory lines, and for confirming the effect of a static eliminator (e.g. the AD-1683).
- Compact and light body
- Large, easy-to-read LCD
- Amount of the electrostatic charge also displayed as a bar graph
- Hold function
- Possible to measure the ion balance of a static elimination device

AND Weighing AD-1689 Calibration weight tweezers, pack of 5
| With a length of 210 mm, the tweezers allow a weight to be placed in a weighing pan without having to put a hand inside the chamber. This prevents convection flow that is normally attributed to heat coming from the hand. |
| Each tweezer is made from austenitic stainless steel (SUS304), therefore heat from the hand is unlikely to be transmitted to the weight via the tweezers. This is especially effective for the precise measurements required of analytical balances.
|
| Tips of the tweezers are covered in resin to prevent the weight from slipping. The hilt is also covered with resin for easy gripping. |
