This accurate and easy-to-use digital device features a pH meter (measures pH from a range of 0 to 14, with an accuracy rate of +/-0.1pH), thermometer (-50°C~70°C (-58°F~158°F)), and a particle meter (0~19990ppm, resolution of 10ppm). It can be used for laboratory or classroom chemistry experiments, or for various household needs, including water purifiers/filters, food (vegetable, fruits) & drink quality monitoring, pools and spas, aquariums, hydroponics, cosmetics/skin care, and much more. The unit provides a digital readout of the pH levels, temperature (in F or C) and particles in Parts Per Million, and features a protective cap. Essential for the lab and classroom, useful for most chemistry instructors, some students. Also includes a small screwdriver for regulating the trimmer. Note that this unit does not include the necessary buffer solution: see related products.
