All defective items must be returned in the original packing with the supplied accessories. GENERAL DESCRIPTION Hanna Instruments pH300, pH301 and pH 302 are professional bench-top pH meters for pH, ORP (Oxidation Reduction Potential), ISE and temperature measurements. Their built-in microprocessor ensures accurate and userfriendly operation. pH measurements are automatically compensated for the temperature effect (ATC). These meters come equipped with a large, easy-to-read LCD which shows the pH or mV or ION (for pH 301 only) with temperature simultaneously. The display has graphic symbols to make the calibration procedure easy to follow. Calibration is not allowed until the electrode has stabilized to ensure accurate measurements. Through the RS 232 serial port you can transfer sample measurements to a PC. 3 TABLE OF CONTENTS Preliminary Examination ................................... 1 General Description .......................................... 1 Functional Description pH300 .......................... 2 Specifications pH300 ........................................ 4 Functional Description pH301 .......................... 5 Specifications pH301 ........................................ 7 Functional Description pH302 .......................... 8 Specifications pH302 ...................................... 10 The Rear Panel ................................................ 11 LCD Functional Description ............................. 11 Operational Guide ........................................... 12 pH Calibration ................................................. 29 pH Values at Various Temperature ................. 39 ION Calibration (for pH301 only) ..................... 40 mv Calibration ................................................. 44 Temperature Calibration ................................. 50 Logging with pH301 ........................................ 55 Programming Functions with pH302 .............. 58 Interface with PC ............................................. 82 Troubleshooting Guide ................................... 83 Electrode Conditioning and Maintenance ...... 84 Temperature-Resistance Correlation for HANNA pH Sensitive Glass ....................... 88 Additional Information about Interface with PC ............................................. 90 Accessories ..................................................... 99 Electrode Application Reference Guide ........ 107 Warranty ......................................................... 108 CE Declaration of Conformity ...................... 109 ISO 9000 Certified Company since 1992 2 FUNCTIONAL DESCRIPTION pH 300 THE FRONT PANEL Keyboard on the Left · COMM to display the current baud rate for RS232.
