Sound Level Calibrator
511E
-
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

Mid-Range Gas Filter Correlation CO2 Analyzer
Model N360M
-
Teledyne Advanced Pollution Instrumentation
The Model N360M measures carbon dioxide (CO2) by comparing infrared energy absorbed by a sample to that absorbed by a reference according to the Beer-Lambert law.The N360M uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO2 known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO2 in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure. A nitrogen purge system is provided for the GFC wheel assembly to eliminate the effects of ambient CO2, if necessary.

Laser Heads
-
The laser head is the source of the laser beam used in all laser motion and position measurement systems. The primary difference between laser heads is in the velocity, reference frequency and optical output power. Other considerations are size, heat dissipation, and input power requirements. Which laser you choose depends primarily on the application in which it will be used. For example, semiconductor lithography systems typically have faster moving parts (stages), and therefore need higher velocities than machine tool applications.
