Extech 610022-B pH Calibration Checker

Troubleshooter tells you if your pH meter is functioning

• Simulates values for pH 4, 7 and 10 (±0.1%FS accuracy)
• Simple to use - connect the calibration cable to device needing calibration and select simulation range
• Easy verification - if your pH device displays the same value that is simulated, then it is working properly and your electrode may need to be replaced
• High Ohm range for industrial applications
