PC keyboard interface for connecting an external keyboard or barcode reader, and software for direct control by PC are included. Built-in printer option is available. Features • 5-point pH calibration by linear regression • Selectable buffer sets • Graphic evaluation possible • Built-in digital recorder • Connection for barcode reader or PC keyboard • User selectable languages • Multi-level GLP functions (password-protected operator levels) • Free-of-charge downloads for MultiLab® pilot or terminal • Four to seven point ISE calibration with a modified Nikolski algorithm • Known addition, double-known addition and known subtraction • Sample addition/subtraction • Blank value addition • Advanced incremental methods • Free software downloads • Comprehensive documentation options inoLab® pH/ION 740/7400* Premium instruments from WTW: Two galvanically isolated inputs allow independent measurements of pH-value, ORP or ion concentration. For accurate measurements along the characteristic curve of the electrode, it is possible to carry out calibrations with up to seven standard solutions. The calculation of the calibration curve by using a modified Nikolski algorithm also takes the non-linear parts of the curve into account. The following methods are used to evaluate the ionic concentration: • Known addition/known subtraction • Sample addition/sample subtraction • Double known addition • Blank value correction • Known addition with blank value correction • Reference measurement • Two galvanically isolated pH/mV/ISE inputs • Menu-operated with back-lit graphic display • One pH and one ISE calibration record per each input inoLab® pH/ION/Cond 750/7500* This instrument also features the option for conductivity measurements. Not only can specific resistance, salinity, and TDS be determined, but also sample-specific temperature coefficients. A wide range of additional functions like data administration, PC-operation using MultiLab® pilot, GLP-compliant calibration and data recording make this instrument essential in every laboratory.
