Generic pH02 Digital LCD pH Meter Pen Tester 0.00-14.00 pH Range - Blue

The meter features two-point automatic calibration. Use the included pH 4.01 and pH 6.86 buffer solution powders to prepare calibration standards. Follow the manufacturer's instructions to initiate the calibration mode, typically involving immersing the probe in the first buffer, confirming the reading, then repeating with the second buffer. Regular calibration ensures ongoing accuracy.

The Generic pH02 pH Meter Pen is designed to operate accurately within a temperature range of 0 to 80 degrees Celsius. This wide range allows for reliable measurements in both cold environmental samples and warm laboratory or industrial liquids. The instrument likely includes automatic temperature compensation to adjust readings across this span.

The pen is powered by two standard 1.5V LR44 button cell batteries. Battery life depends on frequency of use, but due to the meter's typically low power consumption during measurement and an auto-off feature common in such designs, a single set can last for several months of regular intermittent use. Always use fresh batteries for the most accurate readings.

This pen-style pH meter is specifically designed for testing aqueous solutions. For soil pH testing, you would need to create a soil slurry or solution extract using distilled water and then test the liquid portion. Direct insertion into dry soil is not recommended as it can damage the sensitive glass pH electrode and provide inaccurate readings.
