Package – YSI & Bladder Pump

Combining an award winning YSI multiparameter meter with a small, portable, very efficient pumping package that includes a built-in, high efficiency electrical compressor and optional auto shut off. The small electric compressor uses an external rechargeable lead acid battery and no air makes contact with the sample liquid. There is no sample cross-contamination because the stainless steel pumps use a replaceable bladder either in Teflon or PE for easy cleaning. The ideal low flow groundwater sampling package capable of pumping from depths of up to 60 metres.
