cause a large fluctuation in output signal. For best results, use electropolished SS tubing

Note #4: Becauseofthediffusionofairthroughcompositionmaterials, only dual stage SS regulators with metallic diaphragms should be used in conjunction with the sample and supporting gas

supplies.

Note #5: Regulators must be thoroughly purged (burped) prior to use.

2.3.1 Reference Gas.

A cylinder of gas of fixed composition is required as the reference for comparison with the sample gas. A total lack of impurities in the reference would be ideal but is not necessary. An impurity concentration of up to 50% of the narrowest range of interest is tolerable. The exact composition of the reference gas is academic as long as the user is certain that it falls within the limits specified in Section 7 of the manual. The important consideration is that the compositionofthereferencegasremainunchangedwheninuse.

NOTE: When it becomes necessary to replace the reference gas, the analyzer will have to be recalibrated.

2.3.2 Zero Gas.

A supply of gas, composed of the background gas of the analysis and the lowest attainable concentration of impurity, will be required to standard- ize one end of the ranges of interest. The composition of the zero gas must be known to the same exactitude expected of the analysis. TAI suggests that the gas be obtained from a supplier that will certify its composition. Recom- mendations as to the composition of the gas will be found in Section 7 of the manual.

2.3.3 Span Gas.

A supply of gas, composed of the background of the analysis plus a known concentration of the component of interest, will be required to stan- dardize the sensitivity of the analyzer. Again, the composition of the gas must be known to the same order of accuracy expected of the analyzer. Analysis and certification of the composition is desirable. Specific recom- mendations governing the composition of the span gas will be found in Section 7 of the manual.

212R specifications

Teledyne 212R is a state-of-the-art underwater acoustic modem designed for robust communication in various marine environments. This advanced device is based on established principles of underwater acoustics and modern digital signal processing technologies, making it an optimal choice for applications ranging from oceanography to underwater robotics.

One of the standout features of the Teledyne 212R is its high data transmission capabilities, allowing for reliable communication at distances of up to several kilometers depending on environmental conditions. The modem supports various data rates, enabling flexible adaptation to the needs of different applications. This versatility makes it suitable for both low-bandwidth telemetry and high-data applications, such as video streaming from underwater drones.

The Teledyne 212R employs advanced modulation schemes that enhance its performance in challenging conditions. These modulation techniques, combined with sophisticated error correction algorithms, ensure the integrity of data transmission even in noisy environments. This resilience is crucial as it enables the modem to maintain communication in the presence of marine life, background noise, and varying temperatures.

Another remarkable characteristic of the Teledyne 212R is its compact and rugged design. Built to withstand harsh marine conditions, the modem is encapsulated in a pressure-resistant housing, making it suitable for deep-sea operations. Its durability ensures longevity and reliability, reducing the need for frequent maintenance or replacement, which can be costly in remote underwater settings.

Moreover, the modem features an array of integrated sensors that allow for real-time environmental monitoring. This capability can be pivotal for research organizations studying marine ecosystems or for oil and gas companies conducting underwater surveys. The ability to collect and transmit environmental data alongside operational data streamlines data-gathering efforts.

Ease of integration is another key aspect of the Teledyne 212R. It is compatible with a multitude of existing marine technologies and communication protocols, allowing for seamless deployment in diverse systems. This adaptability is essential for users requiring collaborative operations across multiple platforms, such as Autonomous Underwater Vehicles (AUVs) and remotely operated vehicles (ROVs).

In summary, the Teledyne 212R combines high-performance data transmission, advanced modulation techniques, rugged design, and environmental monitoring capabilities. This makes it an essential tool for anyone engaged in underwater research, exploration, or resource management, establishing it as a go-to choice in the field of underwater communication.
