Mid-Range Gas Filter Correlation CO Analyzer
Model N300M
-
Teledyne Advanced Pollution Instrumentation
The Model N300M is a microprocessor-controlled analyzer used to determine the concentration of carbon monoxide (CO) in a sample gas. The analysis method is based on the Beer-Lambert law.The N300M 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 CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO 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.

1.5 GHz, 1 MΩ, 0.9 pF Active Probe
ZS1500
-
Engineers must commonly probe high frequency signals with high signal fidelity. Typical passive probes with high input R and C provide good response at lower frequencies, but inappropriately load the circuit, and distort signals, at higher frequencies. The ZS Series features both high input R (1 MΩ) and low input C (0.9 pF) to reduce circuit Loading across the entire probe/oscilloscope bandwidth. The ZS1500 is ideal for 1 GHz and lower oscilloscopes.

RF Filters
-
RF Filters block unwanted frequencies when testing electronic devices for emissions during EMC testing. They attenuate unwanted frequencies and allow the desired signals through. The RF filters isolate the device under test from external RF noise, this increases the reliability and accuracy of the EMC testing by preventing out-of-band noise and harmonics.

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.
