A new direct reading purity indicator, calibrated both in specific resistance and parts per million, tells at a glance the quality of water produced. A l s o indicates when cartridge change can be expected. Improved high capacity cannister cartridge removes more than 1 1 0 0 grains of salts by ion exchange and has How rate of 5 to 8 gallons per hour. The sturdy cast base is practical for bench or shelf use and is removable for wall mounting. The Barnstead Bantam Demineralizer is supplied complete with closely adjustable needle valve for inlet water, drain petcock, rubber delivery tube, copper inlet pipe and electric cord. For 115 volt, 5 0 - 6 0 cycle operation. N o . 4837 B a r n s t e a d B a n t a m izer, less c a r t r i d g e N o . 4837-C Cartridges, each Lots of six c a r t r i d g e s
