Spectrophotometer UV-VIS PB2201 for ecological laboratories
Spectrophotometer UV-VIS
Models: PB2201A, PB2201B, PB2201C
The PVN-spectrophotometers “SOLAR” operate at ultra-violet, visible and short-range infrared spectrum range. In ecology, spectrophotometers are used to control the quality of water, soil, air in environmental and sanitary research, as well as in the analysis of raw materials, finished products, chem. products, etc.
The spectrophotometer PB2201 meets all modern standards of measuring instruments and is indispensable in laboratories in the field of environmental protection. Its characteristics make it possible to conduct any research within the framework of the necessary methods and to maintain a high level of environmental safety.
The large cell section of the spectrophotometer allows to change easily and quickly cell holders and annexes for carrying out various measurements
Measurement accuracy
Double monochromatic device provides the minimum level of the disturbing radiation that guarantees high precision of measurements
Profitability
The pulse xenon lamp is used as the only light source in the PVN-spectrophotometer. The service life is almost unlimited, unlike halogen and deuterium lamps. Besides convenience in operation, it significantly decreases service expenses
Operation is more simply and quicker
The stray light doesn't influence the accuracy of measurements thanks to use of pulse xenon lamp. Working with the studied samples can be carried out at open cell section. There is no need to spend time for closing and opening cover during operating time
Touch screen
To work in the autonomous mode (without connection the spectrophotometer to the computer) conveniently thanks to existence of the big display with the touch control panel
Built-in printer
Printing of measurement results without connection the spectrophotometer to the computer thanks to the built-in thermal printer
Program support
Specialists of research department and development constantly improve the "UV-VIS Spectrum" program for operation spectrophotometers with computer. "SOLAR" provides to users free updates of the program during all term of device operation.
