Model 721-722S Visible Spectrophotometer

1. The new single-chip system has strong functions, small size and easy maintenance.

2. It is made of flame-retardant and insulated plastic case with exquisite shape design, convenient operation and high safety factor.

3. True 4-digit LCD display with large measurement range and high calculation accuracy.

4. Membrane keyboard, good hand feeling, dust-proof, waterproof and easy to clean.

5. Advanced optical system design, sealed grating monochromator, adopts scientific anti-mild technology, eliminates astigmatism technology, and significantly improves the service life, stray light, stability, and metering accuracy indicators.

6. Use lens concentrating to prevent the energy from plummeting after the mirror is ablated for a long time.

7. Dedicated precision lamp holders, which can replace the tungsten halogen lamps without having to adjust the optical path again.

8. Automatically adjust 0%, 100% and absorbance OA.

 

Model 752N UV-Visible Spectrophotometer

1. The new microcontroller system has the advantages of strong function, small volume and simple maintenance.

2. Use flame retardant, insulating plastic shell, beautiful shape design, easy operation, high safety factor.

3. The real 4 bit LCD shows that the measuring range is large and the calculation accuracy is high.

4. Thin film keyboard, good handle, dustproof, waterproof and easy to clean.

5. Advanced optical system design, sealed grating monochromator, adopt scientific anti mold technology, eliminate miscellaneous and astigmatic technology, significantly improve the service life, miscellaneous light, stability, and light measurement precision index. Halogen tungsten lamp and deuterium lamp use lens concentrator to avoid the energy drop of the reflector when it is ablated for a long time.

6. The special precision lamp holder can replace halogen lamp instead of adjusting the optical path again.

7. It is convenient and safe to switch tungsten halogen lamps and deuterium lamps with buttons.

8. Automatic adjustment of 0%, automatic tune 100% and absorbance OA.

9. It has the functions of "concentration direct reading" and "concentration factor.
