Absolute Encoder The Autosampler consistently tracks the tray position without the need to “home” or calibrate. Barcode Reader A USB-compatible barcode reader can be used to associate names with each sample for improved organization of data. Optical IR Beaker Detection An optical IR beam is able to detect the presence or absence of beakers within the sample tray. Users can dictate the Autosampler action if a beaker is missing from the tray during a titration sequence. If a beaker is detected as missing, the HI921 can skip over the sample or stop the titration sequence. Versatile Electrode Holder The durable electrode holder is able to accommodate three 12 mm electrodes, a temperature sensor, one aspiration tube, and five multipurpose tubes. The multipurpose tubes can be utilized for actions such as reagent addition or burette dosing. Electrode Rinse Feature Up to 3 beakers per tray can be designated for electrode dip/spray rinses. Sample Leveling Feature Automatic leveling for fast preparation of volumetric samples. Waste Removal Feature Aspirate completed samples into a waste container. Use with the HI932 Automatic Titration System Flexible, accurate detection of the titration endpoint with HI932 potentiometric titrator. Real-time progress of the sequence and results shown on the HI932 titrator screen. Control Panel The included control panel features multiple buttons to allow for manual operation of the Autosampler tray, electrode holder, and any auxiliary pumps. A two-line backlit display on the handheld panel clearly displays status information. Manual control with the control panel is desirable for calibration, sample preparation, and method optimization. 4 Titration 4.13 www.hannainst.com |
