Silica Analyzer



Waltron’s 3041 Silica Analyzer is the first choice for online analysis of dissolved silica in ultrapure water applications.

The 3041 is trusted world wide to deliver accurate and reliable readings with minimal maintenance and low total cost of ownership. Common application points in a boiler system for online silica measurement include: make-up water, condensate, boiler feedwater, saturated steam/main steam and cooling water.

Direct Connect Weather Station (RS232)



WeatherHawk 232 Direct Connection weather stations are preconfigured to measure wind speed, wind direction, air temperature, relative humidity, barometric pressure, solar radiation and rainfall. All optional user software selections enable display of sensor information.

The WeatherHawk weather station is designed for easy installation and use by consumers, educators, students, and resource managers. WeatherHawk is ideal for applications where ease of installation and use are key factors. WeatherHawk is preprogrammed to provide simple meteorological data, including the complex calculation of ETo (evapotranspiration) typically used for landscape and crop management. WeatherHawk also conforms to many existing home automation protocols
