The unique double junction electrode and increased reference gel volume makes these testers ideal for chemical applications, food plating baths, or wastewater where sulfides or organics would destroy and ordinary pH electrode. You can also use these instruments in lab applications where solvents, chemicals or biological materials make ordinary testers impractical.
For added accuracy, try the Double Junction pHTestr 20 or pHTestr 30.
