Air Leak Testers
Leak testing is an important quality control test in the manufacturing industry. Since there is no such thing as a completely leak-free component, the key is to determine what leak rate is acceptable in order to manufacture products that are safe and adequate for the customer’s needs. Once the consequence of a leaking product is determined, it can help guide what type of test method is most practical based on budget and technology required to perform testing at the determined specifications.

RF Test Spectrum Measurements over CPRI
Integris 3000
Most modern cell tower network configurations place the Remote Radio Head (RRH) at the top of the tower and the baseband unit(BBU) at the bottom of the tower. While this configuration is advantageous for both computational efficiency and mitigation of RF loss across the cable, it means the only place along RF can be accessed is at the top of the tower. This forces field technicians to have to climb the tower to measure and debug RF noise problems.

Zero Air System
Model T701
Teledyne Advanced Pollution Instrumentation
The T701 adds Modbus TCP/IP connectivity to the proven reliability and performance of our zero air systems. This allows remote monitoring of key instrument functions including dewpoint status, scrubber temperature, box temperature, and output pressure. Additionally, this digital access provides the ability to remotely disable the internal pump, allowing longer service intervals and less power consumption. The user can also remotely start instrument warm-up prior to arrival at the site.The T701 is a fully self-contained source of clean, dry air for dilution calibrators. It can also be used to create purge air for permeation tube ovens or burner air for FID analyzers. The T701 includes a dewpoint sensor, an oil and diaphragm-free pump, and scrubbers to remove SO2, NO, NO2, O3, H2S, and NH3. Optional high performance scrubbers are available to remove CO and Hydrocarbons.
