pH42 Microprocessor pH Tester with automatic temperature compensation

The Sharp pH Tester Series features an extendable cloth reference junction system which eliminates reading errors from clogged junctions. Using tweezers, the cloth junction can be extended to expose new unused portions greatly extending the life of the electrode.

The Sharp Tester microprocessor provides the user with push button calibration and automatic buffer recognition. Auto Shut-off after 10 minutes saves on battery life. All Sharp injection-molded testers are built with a rugged "one piece" splash-proof casing preventing water infiltration immersible up to the LCD.

pH42 is a pH tester with 0.00 to 14.00 pH range and ±0.02 pH accuracy, supplied complete with calibration solution and batteries.
