CONTINUOUS FLOW TITRATOR The HACH Model 1407 makes continuous titration easy. Here is the ideal instrument for alkalinity, hardness, acid-base, and most titrations where there is a color change at the end-point. A sample stream, a colorimetric indicator stream and a titrating reagent stream are blended and pass through the analyzer continuously. The rate of flow of the titrating reagent is adjusted automatically so that a color change end-point is maintained in the stream mixture. The concentration of the substance being determined is indicated on a 16 inch graduated scale. A recorder may be added when a permanent record and/or alarm or control functions are desired. Maintenance is kept to a minimum. Monthly reagent refill, weekly colorimeter adjustment and periodic lubrication will insure long troublefree operation. The HACH Model 1407 is shipped set-up for a specified titration with all necessary fittings, month supply of reagents, hoses, gray steel case and operating instructions. Base price $1,695.
