Autosampler connectivity The HI932 works seamlessly with our HI922 Autosampler featuring 16 or 18 sample tray options, automatic tray identification, and automatic beaker detection. Up to three peristaltic pumps for reagent addition and removal can be connected and real-time analysis and sequencing progress is visible on the HI932 display as well as indicated by the LED lights of the Autosampler. Electrode holder This electrode holder can hold up to 3 electrodes, 4 tubes, and 1 temperature probe at any given time. The holder is angled and the stirrer is removable for access to smaller volume titrations without hassle. Use electrodes with different diameters when needed by simply changing the electrode guide. No need to move electrodes around, get the best tube alignment for your titration with a rotating holder. For a more compact design, the electrode holder is mounted directly onto the titrator body. The press-to-release button makes for simple height control. Need to save more space? Just reverse the holder to accommodate larger beakers. The electrode holder is easy to flip to gain added height. Smarter stirring The removable overhead stirrer has built-in speed control for more consistent stirring.
