HI 98230 • HI 98240 Portable, Printing and Logging pH/ORP/°C Meters with GLP

• Built-in Printer. - Uses plain paper to print hard copies of data.
• "Intelligent" Electrode Technology. - Allows the electrode to memorize the calibration date and data performed with a specific instrument.
• Extended pH Range. - From -4 to 19.99 pH
• Dual Level Backlit LCD - Unsurpassed visibility of measurements.

The top-of-the-range HI 98230 and HI 98240 portable pH meters offer all the features of HI 98140 and HI 98150 with the advantage of having a built-in plain paper printer. Featuring GLP (Good Laboratory Practice) capabilities, these instruments incorporate Hanna’s latest “intelligent” electrode technology. These pH electrodes incorporate a chip which memorizes the calibration data performed with a specific instrument. The meter and electrode recognize each other and you can calibrate a series of electrodes for specific applications and swap them without needing to recalibrate the meter! This new technology allows the operator to optimize time and efficiency with unsurpassed safety. It also avoids erroneous measurements due to the pH electrode having been substituted after calibration. This advanced series of electrodes also incorporates a temperature sensor, eliminating the need for an additional temperature probe. HI 98230 and HI 98240 allow the user to print a permanent undisputable record of the measurement data at any time for record keeping, troubleshooting or compliance purposes. The printing interval is user selectable from 1 to 180 minutes. When the logging mode is activated the instrument stores the measurement data which can be printed directly or at a later date. The stored data (up to 500 measurements) can also be downloaded to a PC with a standard RS232 serial connection and Hanna’s infrared adapter and Windows® compatible software. HI 98230 and HI 98240 also feature a dual-level backlit LCD which facilitates operation in dimly lit areas. Graphic symbols and messages on the LCD guide the user through the measurement procedures as well as during calibration. The pH range has been extended to -4.00 to 19.99 pH and pH calibration is automatic at one or two points with five stored buffer values (pH 4.01, 6.86, 7.01, 9.18 and 10.01). The meter also allows the operator to set a calibration max. time that will alert the user when recalibration is necessary. Access to the GLP data is password protected for added safety. All pH measurements are automatically compensated for the effects of temperature and a stability indicator will appear on the display when the pH measurement is stable. HI 98230 and HI 98240 are each supplied with HI 1618D intelligent electrode with built-in temp. sensor, DIN, 1 m (3.3’) cable, 12VDC adapter, pH 4.01/7.01 buffer solutions, cleaning sol., 5 rolls of printer paper, batteries, hard carrying case
