The HI921 Autosampler is an automated titration sample handling system designed for use with the HI902C Automatic Titration System. This high quality system makes the titration of multiple samples quick and easy. The HI921 Autosampler interfaces directly with the HI902C to access titration methods, allowing up to 18 samples to be run consecutively. The HI921 can utilize up to three peristaltic pumps for reagent addition, sample leveling, and waste aspiration. An included control panel allows for manual operation of the motors and pumps. The Autosampler also features a built-in magnetic stirrer or optional overhead stirrer, status indicator lights, USB interface with compatible barcode reader, and built-in RFID for each tray.   Intuitive Automation   Chemically Resistant Pumps   You can connect up to three peristaltic pumps on the HI921 Autosampler. These peristaltic pumps use high performance plastic, engineered to be chemically resistant with a long service life. Each pump has a flow rate greater than 200 mL/min and can be used for reagent addition, sample leveling, or waste removal. Multipurpose Arm   The Autosampler’s durable electrode holder is able to accommodate three 12 mm electrodes, a temperature sensor, one aspiration tube, five multipurpose tubes, and an overhead stirring assembly, allowing for maximum versatility. The multipurpose spaces can be utilized for a variety of functions including reagent addition or burette dosing. Autosampler Status Indicator   Highly visible status lights are located on top of the Autosampler. These lights correspond to the status indication on the HI902C titrator display and can clearly be seen from a distance. These indicator lights double as a safety feature and serve to automatically stop the current titration sequence with a simple press. Carousel Functionality   Choice of Sample Trays   The HI921 is able to automate samples using a 16 or 18 sample tray. The 16 sample tray accommodates 150 mL beakers while the 18 sample tray holds 100 mL beakers. The trays are composed of chemically resistant material and are easily removable. Each tray is dishwasher safe, providing a quick and simple way for users to clean regularly. Automatic Tray Recognition   The HI921 sample trays feature a built-in RFID reader that’s able to detect and communicate the size and serial number of any tray on the carousel. Users can set up multiple trays designated to differing sample sets without confusion. The RFID reader will ensure that the appropriate tray is used each time. Optical IR Beaker Detection   An optical IR beam is able to detect the presence or absence of each beaker within the sample tray. A user can select which action the HI921 should take if a beaker is missing during a titration sequence. The Autosampler may be programmed to skip the missing beaker, pause, or stop the titration sequence. Smart Positioning   The HI921 contains an absolute encoder that can track the tray position without needing to return “home” or calibrate. The encoder retains the position information when powered off and is readily available when powered back on. Integrated Magnetic Stirrer   A magnetic stirrer comes built into each carousel assembly. Users simply have to add a small magnetic stir bar to each sample beaker to ensure samples are well-mixed during titrations. An optional overhead propeller stirrer may also be installed as an alternative. The HI921 allows you to easily adjust the stirring speed of both the built-in and overhead stirrers for optimal mixing.     Sample Handling & Recording   Expedited Sample Entry   Sample names can be auto-incremented for speedy and convenient sample sample entry. Configurable Balance Interface   Sample sizes may be automatically communicated from any laboratory analytical balance with a RS232 serial output, saving time and labor. Flexible Sample Assignment   Up to 18 samples may be run consecutively with the options to accommodate up to 3 rinse beakers and 1 storage beaker. Organized Sample Table   A USB-compatible barcode reader may be connected to the Autosampler, associating names with samples for improved recordkeeping. Titration Data & Reporting   Customizable Autosampler Sequences   The HI902C can store up to 100 user-defined or standard titration methods that can be accessed by the Autosampler. Each method may be customized and optimized for sequence performance based on application and user requirements. Detailed Sequence Reports   Autosampler sequence reports detail sample names, beaker positions, sample sizes, and results for the sample tray in addition to detailed titration reports for individual samples. Customizable Titration Reports   Each titration report is fully customizable so users can be confident they are storing and filing the appropriate data required for their application and procedures.     SKU HI921-web Product Name Autosampler for Potentiometric Titrator - HI921 Quote Required Yes Weight 20 lbs read more

The 0.1° Resolution K-Type Thermocouple Thermometer with High (Hi) and Low (Lo) Limit Display - HI93531 is a digital, waterproof thermometer. This meter offers high accuracy temperature measurements using a wide variety of interchangeable K-type probes. All readings are displayed on the easy to read LCD, along with the high and low temperatures, temperature units, and a battery indicator upon startup. High and low-temperature display °C/°F readout HOLD function The HI93531 is a 0.1° resolution K-type thermocouple thermometer that can be used with a wide variety of K-type probes. This thermometer offers temperature readouts in both degrees Celsius and Fahrenheit. Featuring up to ±0.5°C accuracy and high and low limit temperature display, the HI93531 is perfectly suited for high accuracy temperature measurements in the laboratory or field.   Features at-a-glance Interchangeable Probes - A wide range of K-type thermocouple probes are available to meet the specific needs of users. Any of the HI766 series of probes can be interchanged with the HI93531 to measure the temperature of surfaces, gases, air, liquid, semi-solid samples, and more. °C/°F Readout - Measurements can be displayed in either degrees Celsius or Fahrenheit. A simple press of the °C/°F button will switch between the scales. High/Low Function - The maximum and minimum temperature values are continuously monitored and displayed on the lower portion of the HI93531 LCD display during a measurement session. The CLR button clears the high and low values on the LCD display. HOLD Function - The HOLD button on the face of the meter freezes the display to allow the user time to record readings.
