This portable pH testkit supplies you with fast and accurate readings that are much more precise than litmus paper and standard pH test kits. The digital meter uses an advanced pH sensitive electrode that can be easily unscrewed and replaced with a new probe when worn, thus making it one of the most durable pH meters on the market. This kit measures pH in a range of 0.0 to 13.0 with a resolution of 0.1 pH and comes complete with 2-point calibration solutions PH-SOL4 and PH-SOL7 for high accuracy testing.
To use the meter, simply dip the probe into each solution and adjust the screws on the top of the unit to calibrate the meter to match the 4.0 and 7.0 pH rating of the solution. Once set, the meter is ready to use. It is advisable to re-calibrate the tester once a week if you plan on using it on a daily basis.
