The Beverage Doctor portable pen style pH meter is an excellent value for all of the included features. It is extremely accurate with a resolution of 0.01 pH. It is entirely waterproof and made of high quality components and includes automatic temperature compensation (ATC). The probe is designed to be easily and affordably replaced when needed. The cap seals perfectly over the probe to prevent it from drying out and decreasing its lifespan.

The Pen Style pH Meter is very easy to calibrate. You simply insert the probe into the pH calibration solution closest to the pH of the sample you want to test and push the CAL button, it will detech which solution value it is and then auto calibrate in less than 5 seconds. It features a 3 point calibration, allowing you to cliabrate the pen at 3 different standard levels -4.00, 6.86, and 9.18. These standards are included with the pH meter.
