Mid-Range Gas Filter Correlation Carbon Dioxide Analyzer
Model T360M
The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T360M comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Sound Level Meters
HD 8701
The sound level meter HD 8701 is a portable instrument, easy and quick to use, suitable for measuring industrial and civil noise levels. The noise levels can be read easily in dB (A) on the large liquid crystal display which also shows all the information concerning the mode of operation of the instrument. One second after switching on and with a resolution of 0.1 dB, the digital reading gives the continuously updated value of the RMS sound pressure level, with a type A frequency weighting. The single range from 30 to 130 dB further simplifies the use of the instrument, as the user does not have to change scale.

Cross-Spectrum CPB (Constant Percentage Bandwidth) Analysis
CPB analysis is used for fractional octave spectral processing of signals coming from the input channels of FFT spectrum analyzers (in real time or recorded time realization view mode), as well as for viewing various spectral characteristics of signals. CPB analysis is used for separating signals into basic constituents in the frequency area in 1/3-, 1/12-, 1/24-octave spectral bands. The software is used for noise spectral analysis within the scope of acoustic and vibrational measurements.
