Spectral Tubes

We are manufacturing 8 difference types of Spectral/Discharge Tubes. a. Argon b. Carbon Dioxide c. Helium d. Hydrogen e. Krypton f. Mercury g. Neon h. Water Vapour Spectral tube Safety: A current limiting transformer protects the tubes. A productive shield also helps safeguard the tubes, while blocking unwanted ambient light for clear viewing Power Requirements: 220VAC, 50Hz
