The Omni sampler is one of the quietest and most intuitive pump to use. We have produced a simple four button design (UP/DN/ESCAPE/ENTER) which has proven remarkably instinctive to use. The proof of this is demonstrated by the “OMNI TUTOR”. This entirely new concept in training provides an interactive instruction manual which allows the pump to be virtually run on your computer screen.
Another major achievement of the Omni is one point calibration. From 3-12 lpm, calibration at any place near midrange will result in 1% precision. Calibration at the exact flow rate will result in 0.5% precision. Excursions from these superb figures occur at 2 lpm (for which the pump is not rated) wherein the precision is only 2%.
A flow rate of up to15 lpm has been provided for the use of Impactor Cassettes, so important for viable samples. The maximum run time at this flow rate is 20 minutes, which exceeds the recommended run time of the cassettes.
The Omni has been tested for RF emissions and substantially exceeds the requirements of Boeing D6-16050-4, Rev D for electromagnetic emissions by electronics used on board commercial aircraft. It can therefore be safely used on a airplane while inflight.
Calibration
The finest samplers deserve the finest calibration equipment. All our OMNI samplers will directly “talk” to our calibrators for flow rate calibration purposes. No intermediate couplers or translators are necessary. The tetraCal® and deltaCal are NIST traceable and the only electronic volumetric calibrators usable down to -30°C.
