  • UV Absorption O3 Analyzer​​​

    Model N4​00 - Teledyne Advanced Pollution Instrumentation

    The Model N400 Ultraviolet (UV) Absorption analyzer uses a system based on the Beer-Lambert law for measuring low ranges of ozone in ambient air. A 254 nm UV light signal is passed through the sample cell where it is absorbed in proportion to the amount of ozone present. Periodically, a switching valve alternates measurement between the sample stream and a sample that has been scrubbed of ozone. The result is a true, stable ozone measurement.

  • Relay / Magnetic Field Testers

    PeakTech Prüf- und Messtechnik GmbH

    Ideally suited for checking magnetic fields and the correct function of coils, e.g. Relays and solenoid valves. The magnetic field detector works without contact, so that opening the housing is not necessary in most cases. When a magnetic field is detected, the probe tip lights up permanently blue, with clocked relays in the same cycle as they are controlled. The function of the magnetic field detector can be checked before each measurement with the enclosed test permanent magnet.

  • Tunable Diode Laser Gas Analyzer​​​​

    Model LGA-4000Z - Teledyne Analytical Instruments

    Teledyne’s LGA-4000Z series leverages the latest in Tunable Diode Laser Absorption Spectroscopy (TDLAS) to achieve an ultra-fast gas measurement in-line without resorting to extraction and sample conditioning. By tuning the laser to a specific absorption wavelength, based on the gas of interest, the attenuation of the light through a sample cell and the detector can be correlated to the concentration of each g​as, per Beer-Lambert Law. The laser provides a narrow absorption band which minimizes the effect of interfering compounds in the process.
