HZ1902 Dual-beam UV-VIS Spectrophotometer-Petroleum Oil Tester-Huazheng Electric Manufacturing (Baoding) Co., Ltd.

Product Introduction

Its main business is the production, manufacture and sales of electrical equipment and testing instruments.

I. General Information

1.1 Characteristics and Applications

HZ1902is a double-beam UV/VIS Spectrophotometer with a scanning function. It has a wider range of spectrum and is of high quality. Due to its built-in micro-computer system, plus excellent optical and electric circuit system, rational mechanical structure and a large LCD display screen, the instrument will surely be an effective and visual means useful to lab analysis in all kinds of industries.

HZ1902UV/VIS Spectrophotometer adopts a man-machine dialogue operation method. It is easy to learn. Menu at the large LCD screen allows every item to be chosen and accepted corresponding to each operation step. In this way, you can perform function you needed. The change of lamp is simple. By turning several screws, you change the lamp, which will be at the optimal position without being complicated light-adjustment.

Instrument is designed to be protected by software program to restore the instrument to normal work status in a failure.

Being an excellent practical UV/VIS spectrophotometer, HZ1902provides fast and simple analytical methods to be widely used in organic, inorganic, petroleum, pharmacy, environment, bio-chemistry, medicine, food and other national economy departments for QC and QA.
