Core Positioning and Display Features
Choose the plan that suits you best.
High-brightness LED Display:
Equipped with 6-digit or 7-digit red high-brightness nixie tubes as standard, with optional character heights of 20mm and 25mm. The brightness can be adjusted manually or automatically according to the ambient light. Even in direct outdoor strong light, dim workshop environment or long-distance observation (up to 10 meters away), the weight data can be read clearly, completely solving the pain point of blurred display and difficulty in reading in industrial scenarios.
Multi-display Modes:
Supports real-time weight, net weight, gross weight, tare weight, accumulated weight, single weight and other data displays, and can freely switch units (kg/t/lb) to meet the measurement needs of different industries and scenarios; it also supports adjustable decimal places (0-3 digits) to adapt to weighing scenarios with different precision requirements.
Comprehensive Status Indication:
Equipped with various LED status Weighing indicators such as zero position, stability, tare, peak value, communication, alarm and power (for battery-powered models), with clear color distinction (red for alarm, green for normal, yellow for prompt). Operators can quickly judge the operation status of the instrument, find abnormalities in time and handle them, improving operation efficiency.
Humanized Display Design:
The instrument panel has a simple and reasonable layout, with clear buttons and comfortable hand feel, supporting backlight on/off. Some models are equipped with extra-large screens to further improve long-distance readability; it also has a data hold function, which can lock the current weight data, facilitating operators to record and verify, and avoiding misreading of data.
