GR series electronic analytical balances (120~310g/0.1mg, 0.01mg)Detailed product description：

Product Introduction
GR concealed weights
Equipped with built-in weights, automatic calibration, and automatic environment setting
Pioneering the "Easy Access Door System"
200 sets of memory, built-in GLP/GMP/ISO software
Equipped with RS-232C bidirectional interface card,
1. Passed the ISO-9001 world quality control standard and obtained certification.
2. A large memory that can store 200 sets of weighing data for users to read at any time.
3. Pioneering the "Easy Access Door System". Using the most ergonomically designed Front Door Control Lever, the opening and closing of the glass doors on both sides are controlled by the front of the balance.
4. The balance can automatically detect the working environment and adjust the three-stage response speed (Automatic Response Adjustment).
5. All day automatic self calibration system, the balance will automatically detect the environment after being powered on. When the temperature changes by more than 1.9 ℃, the balance can be fully calibrated without human operation.
6. Equipped with calibration weights and a One Touch Calibration function, it simplifies the previous tedious calibration steps and can be automatically completed with just one press of the calibration key (CAL).
7. It has the function of Calibration Test, and the display screen will show the zero point value and full calibration value.
8. If the user has a standard weight (E2 level), they can also calibrate the external weight and correct the difference between the internal weight and the standard weight.
The RS-232 C bidirectional interface card is a standard accessory.
10. The lower hook is a standard accessory that can be used for specific gravity measurement or weighing magnetic samples.
11. Equipped with a sensitivity selection key (RANGE), the sensitivity setting can be changed to 0.1mg/1mg according to the user's weighing needs.
12. It has the functions of counting and percentage.
13. Built in density direct reading software, which can input temperature parameters through the panel and directly read density.
14. Equipped with the original factory developed WinCT CD version software, it can automatically input weighing data into the Windows/Office/Excel suite software, and can perform statistical, graphical, curve and other tasks.
15. There are thirteen weight units to choose from, and 1 to 13 weight units or functions can be selected, which can also be freely converted during the weighing process.
16. It has a memo card design that users can refer to at any time.
17. The six function keys are represented in English text and graphics, which are clear and easy to read. Integrated film design, waterproof and dustproof.
18. It has a system self diagnostic function, and various abnormal phenomena will appear on the display screen with codes, greatly reducing the maintenance time.
19. Can input an 8-character identification number (ID Number)
20. Equipped with GLP (Good Lab. Practice) software and the original multifunctional listing machine (AD-8121), it can print date, time, identification number, balance serial number, calibration data, single weight, total weight, frequency, maximum value, minimum value, average value, and standard deviation.

Product Features:
Built in minimum calibration weight, automatic self calibration and single key automatic calibration, automatic environment correction and other functions can ensure accurate weighing. The glass door has an easy to open handle and comes with a standard RS-232 interface and WinCT software that can be connected to a computer or printer. Compliant with GLP and GMP standards.
