Smart printing and weighing electronic scale

The Smart Printing and Weighing Electronic Scale H8 Series is produced by Jiangsu Jutian Weighing Equipment Co., Ltd. It combines static weighing, thermal printing, and data recording within a single industrial-grade device. The equipment is designed for workstations where each weighing operation must be documented with a printed record—such as incoming material inspection, outgoing goods verification, batch ingredient weighing, and quality sampling stations.

Unlike dynamic checkweighers that operate on moving production lines, the H8 Series is a stationary weighing platform intended for operator-attended use. Products or materials are placed on the platform manually or by auxiliary handling equipment; the scale captures the stable weight reading, and the built-in printer generates a ticket, label, or receipt immediately upon command. This workflow is suited to environments where traceable weight documentation is required but integration with an automated conveyor line is not necessary.

Technical Specifications

Additional specifications: Display: LED green digit display; Keypad: 9-key membrane type; Printer: Built-in thermal printer (supports ticket paper and adhesive label stock); Power supply: AC 220V with built-in 8.4V lithium battery (dual-power operation); Communication interfaces (optional): RS232, RS485, Bluetooth, TTL, Ethernet, Wi-Fi, 4G IoT module; Data output options: USB storage, relay signal, 5V I/O, 4-20mA analog output; Frame construction: Carbon steel with baked enamel finish, optional full 304 stainless steel or die-cast aluminum frame; Platform dimensions, weighing capacity, and material options can be configured based on operational requirements.

Jiangsu Jutian operates under ISO9001-certified quality management and holds CE certification for its products. With 68 national patents and 20 software copyrights, the 919 R&D Center develops weighing instruments and embedded software in-house, including the firmware and communication protocols used in the H8 Series. Production is carried out across two manufacturing facilities, with standardized assembly and calibration procedures applied to each unit.

Equipment Construction & Calibration

Platform and frame: The weighing platform is constructed from stainless steel 304 as standard. The frame uses thickened carbon steel with a baked enamel finish for structural rigidity. For environments exposed to moisture, cleaning agents, or corrosive materials, an all-stainless steel 304 frame or die-cast aluminum frame can be specified. The platform is supported by strain gauge load cells selected for the rated capacity of each model.

Printer module: The integrated thermal printer is mounted within the indicator housing, reducing external cabling and protecting the print mechanism from dust and debris. It accepts standard thermal ticket rolls or adhesive label rolls. Print content—including weight value, unit, date/time, and user-defined header—is configurable via the keypad. Print speed is approximately 60 mm/s under standard conditions.

Calibration procedure: Each unit is calibrated using certified weights at multiple points across its weighing range before shipment. Zero stability is verified over a 30-minute period. Linearity and repeatability tests are documented internally. A calibration certificate traceable to national metrology standards is available upon request.

Data Handling & System Connectivity

The H8 Series stores weight records locally and supports multiple data output methods. When equipped with optional communication modules, the scale can transmit weight data in real time to a connected PC, PLC, or host system via RS232, RS485, Ethernet, Wi-Fi, or 4G IoT. Data format is configurable—continuous output, command-response, or print-triggered transmission are all supported. USB storage allows batch export of weighing records for offline analysis in CSV format.

For integration with barcode-based workflows, the scale can accept input from a connected barcode scanner to associate weight readings with product codes, batch numbers, or operator IDs. The relay output and 4-20mA analog output options support integration with external alarm indicators or process control systems.

Typical Applications by Workflow Type

FAQ (Frequently Asked Questions)

What types of printing media does the built-in printer support?
The thermal printer accepts standard thermal paper rolls (ticket format) and thermal adhesive label rolls. Print width is fixed per the printer specification; label size compatibility can be confirmed during ordering. The printer does not require ink or toner, as it uses heat-sensitive media.

How is the weighing data formatted on the printed output?
The print template is configurable through the keypad menu. Fields that can be included: weight value (net/gross), unit of measurement, date and time, sequential ticket number, user-defined header text, and barcode (if enabled). Multiple preset templates can be stored for different product types.

Can the scale operate without a power outlet?
Yes. The built-in 8.4V lithium battery provides operational time suitable for mobile use or environments where power access is intermittent. Battery runtime depends on usage frequency and whether the printer is used continuously. The battery recharges when the scale is connected to AC power.

What is the difference between the carbon steel and stainless steel frame options?
Carbon steel with baked enamel finish provides structural strength at lower material cost and is suitable for dry, indoor environments. Stainless steel 304 offers corrosion resistance and is recommended for food processing, pharmaceutical, chemical, or humid environments where the frame may be exposed to moisture, cleaning agents, or mild chemicals.

How is the scale calibrated after installation?
The scale is calibrated at the factory before shipment. On-site recalibration can be performed using certified test weights following the procedure in the user manual. For customers requiring periodic verification, the calibration procedure is documented, and remote guidance is available from our technical support team.
