Introducing the 820 Benchtop Spectrophotometer - the ultimate quality control tool for your business. With its advanced features and intuitive design, the 820 offers accurate and reliable measurements for both reflectance and transmission spectrophotometry.
Equipped with a 7-inch TFT true colour touchscreen display, the 820 provides an easy-to-use interface for users to operate. The device comes with preloaded quality control software, making it efficient and quick to measure samples with repeatability of ∆E*ab,<0.015.
With its flexible design, the 820 can be positioned either vertically or horizontally, allowing for upwards or downwards measurements. It also has 2 illumination modes, pulse xenon lamp and L.E.D., which can measure samples with or without UV included.
The 820 comes with 4 apertures that are automatically recognised by the device, adjusting the optical path accordingly. Its built-in camera allows for easy viewing of the measurement area, ensuring accurate and precise measurements.
For even greater convenience, the 821 comes with automatic calibration by utilising in-built humidity and temperature sensors, making calibrations quick, easy and hassle-free.
In summary, the 820 & 821 Benchtop Spectrophotometers offer an unparalleled level of accuracy, efficiency, and convenience for quality control. Its advanced features and intuitive design make it a must-have tool for businesses looking to ensure consistent and reliable measurements.
Open Transmission bay
Enhance your measurement consistency with our multifunctional transmission sample holder, meticulously designed to secure and position your samples with precision. Coupled with a spacious, open transmission chamber, it not only facilitates swift and effortless sample measurements but also comfortably accommodates samples of all sizes without restriction.
Multi Position
Our 820/821 models that enable swift transitions from horizontal to vertical measurements, and reflectance to transmission in mere seconds, thereby optimising your productivity.
With a design that embodies versatility, the 820/821 models adeptly accommodate a wide range of applications, including solids, liquids, and powders, truly making them a multipurpose solution for all your measurement needs.
Apertures
Comes equipped with four standard apertures: XLAVΦ25.4mm/30mm, LAVΦ15mm/18mm, MAVΦ8mm/11mm, and SAVΦ3mm/6mm. Furthermore, we can offer the option to customise the aperture size to meet your unique requirements. The 820 & 821 automatically recognise aperture changes and intelligently adjust the light path accordingly, thereby ensuring precision and consistency in your measurements.
Inbuilt Camera
The intuitive inbuilt camera offers a clear view of the aperture/sample area, granting you complete control over the alignment of your measurements. This not only ensures accuracy but also allows you to pinpoint exactly where on your product the colour measurement will be taken.
Inbuilt Drawer
A perfect blend of convenience and safety with an built-in drawer, meticulously designed to securely store and protect your valuable instrument accessories.
One Device Multiple Measurement Positions
Seamless adaptability with our CS-820 & 821 models. They are swift in transitions, taking mere seconds to switch between reflectance and transmission modes. Additionally, you can effortlessly shift from horizontal to vertical measurements, allowing you to operate with remarkable efficiency and ease.
