Laboratory spectrophotometers are an integral part of scientific and medical laboratories. These highly technical instruments allow scientists to determine the concentration of metals and other substances in water, providing critical data for water quality assessment and food safety. Kalstein offers several notable models of laboratory spectrophotometers.
Model YR05497 – Portable and Accurate
Kalstein’s portable YR05497 color spectrophotometer stands out for its high precision and portability. This device uses the 45°/0 illumination/viewing method, complying with the CIE No. 15, GB/T3978, GB2893, GB/T18833 standard. The measuring aperture is Φ8mm, and its observers conform to a 2°/10° spectrography. https://kalstein.net/en/product/handheld-color-spectrophotometer-yr05497/
The YR05497 spectrophotometer is characterized by having a minimal repetitive error. Its spectral reflectance has a standard deviation within 0.1%, and the colorimetric value has a standard deviation of ΔE*ab≤0.04. It also has a wavelength range of 400-700nm with a 10nm wavelength step, and a wide reflectance range of 0-200%.
Model YR05474 – High Durability Xenon Lamp
The YR05474 model stands out for including devices with xenon lamps for measurements of 360-780nm wavelength. This model adopts geometric optics of reflectance and transmittance and includes a concave grating spectrophotometric mode. https://kalstein.net/en/product/pulsed-xenon-lamp-benchtop-spectrophotometer-yr053404/
This equipment also stands out for its reflective measurement aperture and its ability to adapt to a wide variety of conditions. Its measures range from Φ30mm/Φ25.4mm to Φ6mm/Φ4mm and in the case of transmittance, it reaches up to Φ30mm/Φ25mm. And like the previous model, it also uses the CIE No.15, GB/T 3978, GB 2893, GB/T 18833, ISO7724/1, ASTM E1164, DIN5033 Teil7 standard.
Model YR01853 – UV-VIS Spectrophotometer Wavelength Range
The YR01853 model stands out for its wavelength range between 190-1100nm with a 2nm bandwidth. The wavelength adjustment is automatic, with a photometric precision of ± 0.2% T, and a photometric repeatability of 0.2% T. This model uses tungsten and deuterium lamps for its functions. https://kalstein.net/en/product/uv-vis-spectrophotometer-yr01853/
This model also presents notable stability of ± 0.002 A / ha 500 nm and a stray light level of ≤0.05% T. The technical specifications of this model guarantee precise and accurate measurements on any type of sample.
Models YR05500, YR05501 and YR05502 – Grating Spectrophotometers with UV, SCI, SCE, and Bluetooth
These models stand out for their diffusive illumination optical geometry. The YR05500 and YR05501 use combined LED and UV light, while the YR05502 only uses combined LED light. All three implement a dual-matrix 256-image-element CMOS image sensor. https://kalstein.net/en/product/grating-spectrophotometer-with-uv-sci-sce-bluetooth-yr05500-yr05502/
The three models have a wave range of 400-700 nm, a wavelength interval of 10 nm, a semiband width of 10 nm, and a measured reflectance range of 0-200%. Also, the measurement aperture varies between models, with the YR05500 and YR05502 having a double aperture of 10 mm/8 mm and 5 mm/4 mm, while the YR05501 has a single aperture of 8 mm/10 mm.
In summary, the Kalstein laboratory spectrophotometer range offers precise and technically advanced devices for measuring metal concentration in water, meeting the highest international standards.
