Structural characteristics

1.Designed ergonomically.

2.High end atmospheric 7-inch color touch screen. Anti impact, scratch resistant, UV resistant, no delay, no dead corners, easy to clean, allowed to operate with laboratory standard gloves.

3.Detachable, frameless air door design. Efficient and adjustable electric motor ensures smooth and accurate opening and closing of the air door; No guide rail, no sliding groove, detachable, easy to observe, clean, and wash. The top air door can be adjusted to electrically open and close with the side door.

4.Fully automatic/three-point/linear calibration. Three point linear calibration, namely zero position, 50% load, and 100% load, reduces the linear error of the balance. Fully automatic calibration with temperature changes and time factors ensures the weighing accuracy and long-term stability of the balance.

5.Rear mounted sensor layout. Unique weighing chamber and chassis design to prevent powder or liquid from entering the weighing chamber; The ultra-low chassis design increases the stability of weighing and improves weighing efficiency.

6.Electronic level guide. When the balance tilts beyond the set error, a visual warning mark appears on the display, and the electronic analog level bubble indicator is triggered, providing intuitive guidance on how to adjust the balance to a horizontal position to ensure accurate weighing.

7.Dynamic graphic display. By observing the rotation of the circular icon, the weighing process can be visually determined. The circular icon is fully covered, indicating that the weighing result is completely fixed. Intuitively inform customers when it is accurate and eliminate the uncertainty factor of the balance.

8.Electric air door, infrared induction control (standard for 390HA, not available for 390HE series). By utilizing infrared sensing technology, the opening and closing of the hood door, the zeroing of the skin, and the selection of functions can be achieved. At the same time, these sensors can be adjusted in three detection angles according to your individual needs and tasks, which is efficient and convenient, reducing cross contamination.

9. MSWMinimum sample weight (in accordance with the United States Pharmacopeia USP)

10.It has a minimum weighing warning function. When the weighed object is less than the minimum weighing Min of the balance, the balance displays LLL and alarms.

11.Multiple communication interfaces. Easy to connect to computers, printers, and other peripherals.

12.Integrated configuration with automatic static electricity removal device (optional). By utilizing the built-in AC pulse technology in the balance, all static charges can be quickly cleared. Place the sample in the weighing room, close the hood door, and the static electricity of the sample will be automatically cleared. Ensure the weighing accuracy, precision, and reliability of the balance.

13.Integrated configuration environment monitoring and compensation (optional). The Prises 390 series electronic balance can compensate for temperature, air pressure, and humidity in the weighing room, further improving accuracy, which is unique among the main brands of electronic balances.

14. Choose a grid scale pan to reduce buoyancy and improve the stability of the balance; Reduce possible powder accumulation and improve weighing accuracy.

15.Optional beaker holder for better fixation of the beaker, convenient operation, and improved weighing accuracy.
