Antenna, Biconical
EM-6912A | 30 Mhz – 300 MHz
A balun, feedline, and element cage give the Electro-Metrics EM-6912A response curves that are almost linear, making it ideal for swept measurements. An added benefit is that the EM-6912A has an improved BALUN design, which makes it insensitive to changes of orientation while vertically polarized. Readings obtained will be the same no matter which element is closest to the ground plane, eliminating a potential source of measurement error.

LC/MS/MS Method Package For D/L Amino Acids
Most important amino acids exist as stereoisomers. D- and L- forms of mirror image isomers, or enantiomers, are named according to their activity on polarized light. By using CROWNPAK CR-I(+) and CR-I(-) columns with chiral stationary phases, the D- and L-forms of amino acids can be analyzed separately. With CR-I(+) elution order is from D- to L-, and with CR-I(-) the elution order is reversed.

Linear Polarization Resistance (LPR) Monitoring
The electrochemical technique, commonly referred to as Linear Polarization Resistance, is the only corrosion monitoring method that allows corrosion rates to be measured directly, in real time. Although limited to electrolytically conducting liquids, the response time and data quality of this technique make it clearly superior, where applicable, to all other forms of corrosion monitoring.

Audio Fiber Tracer
CFT-810
Motorized Polarization Controller. In addition to its basic function of adjusting polarization states in multi channels, it also provides convenient ‘save and recall’ functions. As a Scanning PC, it provides very powerful ‘auto scan’ modes with variable scanning speeds. Polarization states can be manipulated by either manual adjustment or remote control (GPIB, RS-232) using two quarter-wave plates in each channel of the PC1600. Additionally, the auto scan mode of FIBERPRO’s Motorized Polarization Controller has been upgraded in LPC, and it shows another auto scan mode of four quarter-waveplates with higher polarization extinction ratio when connecting two channels at a high speed. PC1600 is an essential tool to complete fiber-optic, multi-channel measurement systems such as WDM/DWDM as well as R&D (i.e. PMD experiments), and manufacturing.
