Inquiry (采购产品): 4000 Series portable analyzers Can an instrument sold as a -199, 200 ppm top end, be refitted with a different cell or electrode so that it will measure 2000 ppm. If not, how much is a -1999 for hydrogen chloride, both as a purchase or as a rental, if possible? I have a client that wants to measure HCl at 1-10 ppm and about 1000 ppm at the same time. I'm assuming that we need two instrunebts, and I've not been able to find a rental available in the 1000 ppm range. Please help.
