Ozone Analyzer Characteristics Continuously measures ozone mixing ratio of air drawn in through Teflon inlet tubing. The measurement method is detection of the absorption by ozone of 254 nm ultraviolet light. Method is very accurate and stable. Analyzer has been intercompared with the ESRL/GMD network standard that has in turn been calibrated against a NIST maintained standard reference photometer. The analyzer has an accompanying zero air source and internal ozone generator that supplies several preset ozone samples to the analyzer. Data (one hour and 5 minute averages) are stored in the analyzer and are downloaded weekly using the accompanying laptop computer (analyzer can also be directly connected to TCP/IP network).

Brief set of Russian instructions courtesy of Sergey Matrosov Инструкция по установке анализатора озона TEI 49i Введение Инструкция предназначена для установки анализатора озона TEI 49i на новой площадке и поэтому включает описание подключения прибора к электроснабжению (для сети 220 В, 50 Гц), а также установку и подключение к соответствующему воздухозаборному шлангу. Принцип измерений анализатора озона TEI 49i основан на поглощении озоном ультрафиолетового излучения на длине волны 254 нм. Прибор поочередно анализирует пробы воздуха, из которых озон был удален с помощью внутреннего катализатора-очистителя селективного действия, и пробы наружного воздуха с озоном. Разница в этих количествах является очень устойчивым показателем содержания озона в анализируемом воздухе. В комплект прибора также входят внешний нулевой источник воздуха (угольная башенка) и насос, подающий воздух во внутренний источник озона, используемый для проверки работы анализатора. Установка анализатора Перед установкой TEI 49i необходимо снять крышку и вывинтить три шурупа, крепящие насос. Прибор снабжен резиновыми амортизирующими прокладками, являющимися частью крепления насоса, поэтому корпус насоса должен быть хорошо фиксирован при транспортировке, чтобы избежать повреждения прокладок. Кроме того, одна из монтажных плат удерживается на месте при транспортировке куском розового пенопласта

Plan for training and deployment Training to take place as part of this visit (Friday morning). Equipment transported to Russia with return of Russian personnel after this visit. Transport of equipment to Tiksi. Temporary installation of ozone analyzer in existing hydrometeorology observatory building – Spring Transfer of analyzer to the hydrometeorology climate/clean air facility – Autumn 2007.
