The PS401 features a dual-purpose design: it can be used as a single unit ("main unit + probe") for handheld measurement needs, or the probe can be used independently for flexible integration into industrial automation equipment. Equipped with USB, Bluetooth, and RS485 and other mainstream industrial interfaces, it supports multi-device communication and collaborative work, allowing for rapid integration into various automated production lines to build distributed color measurement systems and meet the needs of multi-point synchronous color monitoring on complex production lines. It is widely used for color difference quality control in industries such as plastics and electronics, paints and inks, textiles and apparel printing and dyeing, printing, and ceramics.
Handheld + probe dual-use design: It can be operated as a whole to meet the sampling needs of the laboratory or the field; or the probe can be used alone and integrated into automated equipment to adapt to different working scenarios.
Micro-orifice measurement capability: The measuring aperture is only 1mm, making it suitable for precise colorimetric measurement of small samples, fine areas, curved surfaces, or narrow spaces.
Lightweight design: The main unit weighs only 250g, and the probe (including the calibration box) weighs 240g. Its compact size makes it easy to hold or embed in a device.
Built-in electronic color card library: The device has a pre-installed standard electronic color card, so there is no need to carry a physical color card booklet, which can quickly compare the target color with the standard color sample.
One-click matching and filtering: After measuring the sample, the instrument can automatically identify the closest electronic color card number and color difference data, helping users quickly determine the color assignment and degree of deviation.
Highly efficient quality control: In the processes of incoming material inspection, production batch comparison, and finished product sampling inspection in industries such as plastics and electronics, paints and inks, and textile printing and dyeing, the efficiency of color determination is greatly improved and human error is reduced.
Scalability: Supports user-defined import or update of electronic color card libraries, meeting the digital management and application needs of enterprises' own standard color libraries.
Multiple interface support: Equipped with multiple interfaces such as USB, Bluetooth, RS485 (probe end), RS232, and RJ45, it is convenient to connect with PLC, computers, printers, industrial controllers and other devices to achieve high-speed data transmission and system integration.
