Specifications

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.
pH40, pH41 and pH42 are supplied complete with calibra-
tion solution and batteries.
• pH40: pH tester with 0.0 to 14.0 pH range
and ±0.2 pH accuracy;
• pH41: pH tester with 0.0 to 14.0 pH range
and ±0.1 pH accuracy;
• pH42: pH tester with 0.00 to 14.00 pH range
and ±0.02 pH accuracy.
