HR-AZ/HR-A Series Compact Analytical Balances
The HR-AZ/HR-A series of compact analytical balances utilize proven A&D sensor technology to deliver superior performance with accuracy and reliability. Behind their simple design, these balances offer fast stabilization, compact footprint, and essential features for precise analytical weighing.
Available Models
- HR-250AZ / HR-250A: 252 g × 0.1 mg
- HR-150AZ / HR-150A: 152 g × 0.1 mg
- HR-100AZ / HR-100A: 102 g × 0.1 mg
Key Features
Fast Stabilization in 2 Seconds
Compact Super Hybrid Sensor (C-SHS) technology enables high-speed, frustration-free weighing even at a resolution of 0.1 mg.
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.
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.
Design Features
- Rotary Sliding Doors: Requires no extra space at the rear for accessing the weighing chamber, as the doors simply rotate behind the balance
- Removable Breeze Break: Easily removed using a unique clip system, allowing fast, simple cleaning and use in confined spaces like gloveboxes and controlled environment cabinets
- Large Removable Breeze Break with Antistatic Coating: Treated with an antistatic agent to ensure stable weighing, offers a large working space and can be detached for better portability and easy cleaning
- Clear, Reverse Backlit LCD: Black and white display provides excellent readability even in a dimly-lit area
- Front-Mounted Spirit Level: Easily visible when adjusting the leveling feet of the balance for accurate weighing
Functionality
Fourteen Weighing Units
g, mg, oz, oz-t, ct, momme, dwt, grain, tael, tola, pcs (counting mode), % (percent mode), DS (density mode), plus a user-programmable unit for conversion applications like GSM calculations in paper and fabric industries.
GLP/GMP/GCP/ISO Compliant Output
Can output the balance manufacturer, model, serial number, ID number, date and time, space for signature, and calibration records.
Adjustable Response Characteristics and Hold Function
Three preset combinations of weighing speed and stability (FAST, MID, or SLOW) to suit 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.
