1、 Classified by interface type

1. RS232 serial port connection type

• 昆山巨天 JDT-AO919-A35It supports gross weight, net weight, and cumulative functions, and can be optionally equipped with a built-in printer.

• Kunshan Jutian JDT-WN-Q20SStandard RS232 interface, supports 1/60000 high-precision division value, suitable for industrial weighing, with a warranty period of 1 year.

• Kunshan Jutian JW-A1 SeriesSupports RS232 or RS485 interfaces, capable of automatically recording data every minute, suitable for laboratory or production line monitoring.

• featureTo achieve data transmission through a serial port (COM port), parameters such as baud rate (usually 4800), data bits, and parity bits need to be set.

• Applicable Models：

2. RS485 interface type

• featureHalf duplex communication, suitable for long-distance transmission, requires shielded twisted pair cables, commonly used in master-slave networks (such as connecting multiple scales to a computer)

• Applicable scenariosMulti device networking in industrial environments, such as chemical and food processing industries.

3. USB interface type

• featureA-B type USB cable is required, and some models require driver installation (such as configuring a virtual COM port for Windows systems).

• Applicable ModelsSome electronic scales (such as Kunshan Jutian Intelligent Touchscreen Electronic Scale) support data export to Excel and external LED display screens.

2、 Classified by Function and Application Scenarios

1. Laboratory specific type

• Kunshan Jutian JDJW-A1Support automatic recording of weighing data every minute, optional RS232/RS485 interface, suitable for real-time monitoring scenarios such as chemical reactions and biological experiments.

• High precision analytical balanceThe division value is as low as 0.1g, supporting software automatic calibration, suitable for scientific research or pharmaceutical industry79.

2. Industrial production line type

• Kunshan JutianWeighing 300kg, equipped with a built-in thermal printer, suitable for scenarios such as raw material sorting and quality inspection

• Baoheng TCS seriesSupports weighing, counting, and sorting functions, with a division count of up to 30000, suitable for industries such as automobiles and building materials.

3. Data management and analysis oriented

• Kunshan Jutian Intelligent Electronic ScaleSupport exporting data from USB flash drive to Excel, external three color alarm lights, and the ability to generate historical curve graphs through software.

• Regularly record electronic scalesConfigure a data collection system to automatically store data and support remote monitoring, suitable for food processing or warehouse management.

3、 Precautions for selection and use

1. Interface compatibilityConfirm the computer port type (such as COM port or USB), and use an adapter or driver if necessary.

2. Software support: It is necessary to install management software provided by the manufacturer (such as JuTian and proprietary software), or third-party compatible tools.

3. Calibration and maintenanceRegular calibration ensures accuracy, and choosing a brand with a long warranty period can reduce maintenance costs.

4. Application requirementsSelect the appropriate model based on the weighing range (e.g. 1.5kg to 800kg) and division value (0.1g to 100g).
