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.

1. Flexible Application of Dual Modes

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.
