AND HR-250AZ Analytical Balance, 252 g × 0.1 mg, Internal Calibration

Description

The AND HR-250AZ Analytical Balance, 252 g × 0.1 mg, Internal Calibration, also known as a laboratory analytical balance, precision analytical weighing balance or electronic laboratory balance, is designed for accurate mass measurement in research, quality control and analytical laboratories. Manufactured by AND, the HR-250AZ analytical balance combines Compact Super Hybrid Sensor (C-SHS) technology with a maximum weighing capacity of 252 g and readability of 0.1 mg (0.0001 g). It is suitable for applications requiring fine mass resolution and repeatable weighing performance.

The balance provides approximately 2-second stabilisation when configured to FAST mode under suitable environmental conditions. Its adjustable response characteristics help users manage the effects of air movement and vibration. The factory MID setting typically provides a stabilisation time of approximately 3 seconds. A built-in calibration mass allows automatic internal calibration without routinely handling separate calibration weights. This feature supports consistent weighing performance and simplifies routine balance adjustment. The large, removable antistatic breeze break helps protect measurements from air currents and electrostatic interference. Rotary sliding doors provide access to the weighing chamber without requiring additional clearance behind the balance.

With a 198 × 294 mm footprint and overall dimensions of 198 × 294 × 315 mm, the instrument fits conveniently on laboratory benches. Its 90 mm diameter weighing pan accommodates suitable sample containers, while the reverse-backlit LCD provides clear measurement readings. The instrument supports multiple weighing units, including grams, milligrams, ounces, troy ounces, carats, grains and a user-programmable unit. Its display and operating modes provide flexibility for different analytical and laboratory procedures. The counting function includes automatic counting accuracy improvement, with selectable reference sample quantities of 10, 25, 50 or 100 pieces. Percentage weighing allows users to compare sample mass against a stored reference.

Additional functions include statistical calculations, comparator operation with buzzer, hold mode and density determination. An optional density determination kit is available for applications requiring specialised measurement accessories. The balance supports GLP/GMP/GCP/ISO documentation output, including weighing and calibration information. Its integrated RS-232C interface enables connection to compatible laboratory data collection equipment. A built-in clock and calendar support date and time information in measurement records. Automatic power functions, an underhook weighing facility and selectable display refresh rates provide additional flexibility. The instrument operates in ambient temperatures from 5°C to 40°C, at relative humidity levels of 85% or less without condensation. For reliable results, position the balance on a stable, level surface away from strong vibrations, draughts and temperature fluctuations.

Safety Precautions: Do not exceed the 252 g weighing capacity. Avoid weighing hot, corrosive or volatile samples directly on the pan. Use suitable containers, follow the manufacturer’s operating instructions and perform calibration checks appropriate to the measurement procedure. The balance operates using an AC adaptor, with an optional built-in rechargeable battery available separately. USB, Ethernet and density determination accessories are also optional.
