We are a group of scientists and engineers who use carbon dioxide parameters (DIC, TAlk, pH, and pCO2) as measures of biological activities such as biological production and respiration in aquatic environments. We provide you with high quality instruments at affordable prices. We are ready to use our expertise to help address your scientific issues. Apollo SciTech was setup in 2001. Since then we have built the Dissolved Inorganic Carbon (DIC) Analyzer (model AS-C1, C2, and C3, and now AS-C5, C6L, and D1), the Seawater Total Alkalinity Gran Titration System (model AS-ALK1, ALK2, and now AS-ALK3), the Underway pCO2 Monitoring System (model AS-P2 and now AS-P3), and the Spectrophotometric Seawater pH Analyzer (model AS-PH1 and now AS-PH2). A unique feature of our DIC analyzer and TALK titrator is the small sample volume. We have users around the world including the United States, Canada, Mexico, Brazil, Chile, Peru, Denmark, Greenland, France, Germany, the Netherlands, Norway, Poland, Spain, Sweden, Switzerland, Ukraine, the United Kingdom, Israel, Saudi Arabia, the United Arab Emirates, the mainland China, Hong Kong, Taiwan, Singapore, South Korea, Australia, and New Zealand.
