Model 762 UV-VIS spectrophotometer - Model 762 UV-VIS

Our company supply the model762 UV-VIS spectrophotometer to the guests all over the world.

Wuxi Jiebo Electrical Technology Co.,Ltd, is a manufacturer&trading company on analytical instruments.

Features & Applications

UV762 is a double beam scanning ultraviolet-visible spectrophotometer. It has wider spectral range and is of very good quality. Since the instrument is equipped with a powerful micro-computer processing system, excellent optical and circuit system, and applies appropriate mechanical structure, and has a large LCD screen, it has become an effective and important tool for measurement applications at the lab in all industries.

The UV762 UV-Visible Spectrophotometer applies the human-machine operational mode and is quite easy to operate. Users can quickly master the operation skills. The replacement of source lamp abandons the outdated and complicated ways and adopts more simple and easy way. The user can simply rotate a few screws to replace the illuminant light, which guarantees that the lamp is at the best position without complex adjustment.

The software design of the instrument has self-protection function, which ensures the device can restore normal working condition in case of any wrong operations.

As an excellent and useful apparatus, the fast and simple analysis performance allows UV762 to be widely applied to economic departments related to organic and inorganic, petroleum, pharmacy, environment, biochemistry, medicine, food and other sectors. It is one of the indispensable instruments for the conventional quality control (QC) and quality of analysis (QA).
