The instrument should be placed in a dry room and on a sturdy and stable workbench during use. Indoor lighting should not be too intense. In hot weather, please do not direct a fan at the instrument, as this may cause the brightness of the tungsten lamp filament to be unstable.3. Before use, you should understand the instrument's structure, working principle, and the functions of each control knob. Before connecting to the power supply, please check the safety of the instrument, ensure that the power connection is secure, the power supply is normal, and the initial positions of all adjustment knobs are correct, then turn on the power switch.

• 【Build to Last】: Made of premium plastic, this spectrophotometer for color matching is corrosion-resistant, wear-resistant and not easy to deform, ensuring a long service life.The surface of the spectrophotometer laboratory is smooth and the structure is simple. You can easily use a soft cloth (not included) to wipe it clean.Backlit LCD display offers clear visibility of readings in various lighting conditions, enhancing usability.
• 【Precise Measurement】: Featuring a broad 350-1020nm wavelength range for comprehensive visible light analysis, coupled with ±2nm high measurement accuracy, it ensures reliable spectral data acquisition for rigorous scientific research and quality-critical industrial applications.
• 【User-friendly Tool】: Portable spectrophotometer is equipped with an automatic light gate, along with functions for automatic 0 and 100 adjustment and instrument calibration, which streamlines the setup process, reducing the time and effort required for manual calibration.Wavelength adjustment knob enables easy and precise tuning of wavelengths within the visible spectrum, facilitating accurate measurements tailored to specific analytical requirements.
• 【High Clarity】:: With low stray light, it offers high-class optical data, and clearer and more accurate readings, which reduces optical disturbances, ensure reliable results, and thus reduce the number of trial and error attempts.
• 【Stable Performance】: The tungsten lamp light source provides stable illumination, reducing fluctuations in light intensity that could otherwise affect the accuracy of results. Its large sample chamber can accommodate cuvettes up to 3.94 inches in length, increasing experimental flexibility. Heat dissipation holes allow efficient heat release, keeping internal components cool and ensuring stable instrument performance.
