Application:

This instrument is a standard equipment which based on the principle of spectrophotometry. 

It can be measured transmittance or absorbency samples within 340nm-1000nm wavelength range. 

It can be widely applied to Clinical Sanitation, Biochemistry, Environment Protection, Food Inspection, Petrochemical, Tertiary Institutions, Basic Teaching Experiment, etc.

Characteristics:

1. Compact in Size, Novel in Design, Flame Retardant & Insulation Material Skin.

2. 4 Digits LED Display.

1. Automatic Calibration 0%/100% (T) & Absorbency 0 (A).

2. Precise Lamp Holder ensure not readjust optical system while manually replaced lamp for each time.

3. Reasonable Structure, Advanced Optical System, High Quality Airproof VASGM & Prism Monochromator so that boasts superior Resolution, Stray Light, Accuracy and Stability.
