Brewer MkIII Spectrophotometer

Product catalog summary
Overview
The Brewer MkIII Spectrophotometer is a sophisticated instrument designed for high-accuracy measurements of stratospheric ozone and solar ultraviolet (UV) radiation. It is suitable for use in all climates and is the only model currently in production due to its superior capabilities.

Applications
Originally developed for the WMO Global Atmosphere Watch program, the Brewer MkIII is used worldwide to measure total column ozone and UV radiation. It is the only instrument sanctioned by the WMO for these measurements. The Brewer is also used for research into the effects of UV radiation, which can cause health issues in humans and animals, and damage to plants and materials.

Instrument Design
The Brewer MkIII features a unique spectrometer design that compensates for temperature changes, allowing it to operate without complex temperature stabilization. It uses two spectrometers in series for improved accuracy and is mounted on an azimuth tracker for precise measurements.

Features
The instrument includes an internal fan, heater, and humidity sensor. It is transported in a protective case and can operate in temperatures ranging from -20°C to +50°C, extendable to -50°C with an insulated cover.

Specifications
The Brewer MkIII operates with a wavelength range of 286.5 nm to 363 nm and a resolution of 0.6 nm. It uses a low noise UV-enhanced photo-multiplier tube and has a measurement accuracy of less than 1% for column ozone.

Global Presence
There are over 210 Brewer instruments in more than 40 countries, contributing data to the World Ozone & Ultraviolet Data Centre.

Support and Accessories
Kipp & Zonen provides full support, including calibration and repairs. Accessories include a UV-B stability kit and an insulated cold cover for extreme conditions.

Brewer MkIII Spectrophotometer-2

Introduction A major concern in many parts of the world is the amount of harmful ultraviolet radiation from the sun and sky that people are exposed to. ‘Holes in the Ozone layer’ are areas of stratospheric Ozone depletion and are not confined to the North and South Poles. They are indicators of the general health of the atmosphere, and a reduction in Ozone means that more harmful UV reaches the ground. Many Brewers are now purchased for research into the effects of Ultraviolet (UV) radiation from the sun and sky. The UV region covers the wavelength ranges 100-280 nm (UVC), 280-315 nm (UVB) and...
