Finally, Globally Proven Precision
at a Fair Price
What do you expect most from an analytical balance? If you are like us, youwill agree that accuracy and reliability come before anything else. The
HR-AZ/HR-A series, behind their simple design, utilize proven A&D sensor
technology that delivers solid performance to all users who wish to dosuperior work.
Optimizing value, the HR-AZ/HR-A series realizes the following three savings:1. Saving “Time”
Fast stabilization in 2 seconds

Our widely-recognized Compact Super Hybrid Sensor (C-SHS) technology ◆perform high-speed, frustration-free weighing even at a readability of 0.1 mg.

now enables you to◆ Patented

One-touch automatic calibration (HR-AZ models only)

The built-in calibration mass lets you ensure the accuracy of your balance with just one key press.

2. Saving “Space”
Compact footprint: 198 mm × 294 mm

With the C-SHS, the footprint of the balance is smaller than the ISO A4 (210 mm × 297 mm) paper size,maximizing opportunities for use of an analytical balance in even the smallest of spaces.

Rotary sliding doors

Unlike conventional analytical balances, the HR-AZ/HR-A seriesrequires no extra space at the rear for accessing the weighingchamber, as the doors simply rotate behind the balance.

Removable breeze break

The breeze break is easily removed using a unique clip system,
allowing fast, simple cleaning and use in conﬁned spaces likegloveboxes and controlled environment cabinets.

3. Saving “Cost”
Lean design for aﬀordability
The HR-AZ/HR-A design is all about “keeping it simple” without compromising quality orperformance. Key features demanded by today’s market have been included, resulting in a compact,precise, and reliable analytical balance for the value-conscious user.

Superb Usability

Large removable breeze breakwith antistatic coating

The breeze break is treated with an antistatic agent to ensure stableweighing. It also oﬀers a large working space and can be detached forbetter portability and easy cleaning of the balance.

Clear, reverse backlit LCD

Front-mounted spirit level

The contrast of the black and white display provides
excellent visibility even in a dimly-lit area.

The spirit level is easy to see when adjusting the levelingfeet of the balance for accurate weighing.

Great Flexibility and Compliance

GLP/GMP/GCP/ISO compliant output

For compliance and documentation requirements, the HR-AZ/HR-A
series can output the balance manufacturer, model, serial number, ID
number, date and time*1, space for signature, and calibration records.

the HR-AZ models only. Please use the AD-8127*1 Forcompact printer, which has a calendar function, toprint the date and time with the HR-A models.

User access control (UAC) with password function

The balance can be password-protected to allow only authorized individuals to use it or change its settings. It is also
possible to disable any change to the balance settings including calibration or, for HR-AZ models, correction of theinternal mass value.

Adjustable response characteristics and hold function

From three preset combinations of weighing speed and stability (FAST, MID, or SLOW), select the one that best suits
your environmental conditions (drafts and vibrations). A hold function is also available for weighing animals.

Statistical calculation function

The balance displays and outputs statistical calculation data including number of data, sum, maximum,minimum, range (maximum–minimum), average, standard deviation, and coeﬃcient of variation.

Options and Accessories

Quick USB interface (FXi-02)

The easy-to-use USB interface requires no driver orsoftware installation for transfer of weighing data
to a PC*2.

transfer from the balance to a PC only. Please use the RS-232C standard*2 Datainterface with the serial-USB converter (AX-USB-9P, optional) for two-way
communication or sending GLP or statistical calculation information via USB.
Portable memory devices such as weighing environment logger (AD-1687) anddata logger (AD-1688) are also available.

Ethernet interface with WinCT-Plus software (FXi-08)

You can send commands for controlling and acquiring data from multiple balances.

Rechargeable battery unit (FXi-09)

The Ni-MH rechargeable battery pack can be ﬁtted
into the balance for use without AC power (10 hoursof charging for 14 hours of operation).

Density determination kit (AD-1654)

Using this kit, it is easy to calculate the density of asolid or liquid substance in density mode.
