The RADēCO RAD-Pro 12 is an industry leader in back-pressure performance, reliability and ease-of-use. This pump offers flow rates up to 12 LPM respectively. And thanks to several advanced features, this pump overcomes the main causes of sampling errors – saving you time and money. The air flow display holds calibration for 30 days, even with atmospheric changes. While RADēCO air sampling pumps are known for their strength, the back-pressure capabilities of the RAD-Pro 12 are the highest in the industry for any personal sampling pump. With the RAD-Pro 12 there is less risk of lost samples due to battery failure. It incorporates a nickel-metal hydride (NiMH) battery which, unlike a NiCd battery, doesn’t suffer from “memory” problems. So there’s no hidden loss of battery capacity, no shorter-than-expected run time and no need for special battery maintenance. You use our standard charger and get the same, highly predictable life, charge after charge. When the display indicates a “full” battery, that’s exactly what the pump delivers. Plus, the indicator more accurately displays remaining life throughout the sampling period. You get faster charging too. The NiMH battery fully charges in just five hours. And you won’t be hampered with special storage or disposal requirements, since the NiMH battery is friendly to the environment.
