High-precision PH Test Pen: Portable design
Ever wished you could test PH levels without the hassle? Meet our Portable High-precision PH Test Pen—your new best friend for everything from checking your tap water to keeping your fish happy. With a razor-sharp resolution of 0.01PH across a 0.00-14.00PH range, this little gadget doesn't just guess; it knows. And thanks to automatic temperature compensation and a three-point calibration (4.01 / 6.86 / 9.18), it's accurate come rain or shine (or, you know, whatever your testing environment throws at it).
What's under the hood? A probe so sensitive it could probably detect your mood swings, an automatic calibration function that does the thinking for you, and a screen so large and clear you won't need to squint. Runs on 2x1.5V (LR44) button batteries—because who has time for cords? Just a heads-up: it might take a minute to settle down and give you a stable reading in still water. Think of it as the pen getting its bearings.
Inside the box, you'll find: the PH test pen itself, two buffer powders (PH 4.01 and 6.86—because variety is the spice of life), a user manual (for those who read them), and a packaging box. At a compact 15.5x3.1x1.7cm and a featherlight 49g, it's the ultimate grab-and-go tool for PH testing on the fly. No lab coat required.
