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.
Multi-device communication and collaborative work: Supports networking of multiple devices, suitable for multi-point color synchronous monitoring in automated production lines, and building a distributed color measurement system.
External triggering and real-time feedback: Supports external triggering measurement, and can work in conjunction with production line sensors, robotic arms, etc. to achieve automated and synchronized data acquisition, facilitating closed-loop control.
Optical core: It adopts dual-channel silicon photodiode array sensors (32 groups in two rows) and nano-integrated spectral devices, with a wavelength range of 400-700nm, a wavelength interval of 10nm, and high spectral accuracy.
Good repeatability: standard deviation of chromaticity value ΔE*ab ≤ 0.02 (30 measurements at 5s intervals after whiteboard calibration), standard deviation of spectrophotometric reflectance ≤ 0.1% (≤ 0.2% in the range of 400-700nm).
Small inter-device difference: ΔE*ab ≤0.3 (average value of 12 color plates in BCRA series II), ensuring data consistency among multiple devices.
High display accuracy: 0.01%, reflectance resolution 0.01%, reflectance measurement range 0-200%, meeting high-precision quality control requirements.
Rich colorimetric indicators: Supports multiple color spaces such as CIE LAB, XYZ, Yxy, LCh, CIE LUV, s-RGB, HunterLab, βxy, DIN Lab99, etc.; covers multiple color difference formulas such as ΔEab, ΔE94, ΔEcmc, ΔE00, DINΔE99, etc.
Diverse colorimetric indicators: including spectral reflectance, whiteness (ASTM E313, CIE/ISO, ISO2470/R457, etc.), yellowness (ASTM D1925, ASTM 313), metamerism index (MI), staining/color change fastness, strength, opacity, 555 hue classification, Munsell (C/2), blackness (My, dM), color density (CMYK), tint, etc.
Multiple light sources and observer angles: Supports 32 types of observation light sources, including D65, A, B, C, D50, F series, and LED series, with selectable 2°/10° observer angles, conforming to international standards.
Comprehensive software ecosystem: Supports multiple platforms including Android, iOS, Windows, WeChat Mini Programs, and HarmonyOS, and provides quality management software (downloadable from the official website) to enable data storage, analysis, export, and traceability.
Long-lasting light source: Combined full-spectrum LED light source with a lifespan of up to 10 years or more than 3 million measurements, reducing maintenance costs.
High-capacity battery: 3200mAh lithium battery, which can support about 9 hours or 15,000 measurements on a single charge, meeting the needs of long-term operation.
Strong environmental adaptability: operating temperature 0~40℃, storage temperature -20~50℃, humidity ≤85%RH (non-condensing), suitable for industrial site environments.
Metrological compliance guarantee: The equipment is guaranteed to be metrologically compliant at the factory, ensuring that the measurement results are traceable and reliable.
