With this digital pH meter you can measure the pH of what you need in a simple and fast way, obtaining accurate results. In fact, the HI98107 model is used by thousands of people around the world to control pH in laboratories and industrial companies, as well as in agriculture, fish farms, aquariums, in food production and quality control, swimming pools or spas.This HANNA digital pH meter has revolutionized the pH measurement industry, offering all users, without the need to be technical in the field, an accurate, economical and easy-to-use instrument. This type of pocket meter has been completely redesigned based on user experience and needs.The housing of the meter is more robust and its design is ergonomic. In addition, its new design features a larger and more visible screen that allows easy reading from any angle.Due to use and the passage of time, the joints become clogged or contaminated, and if there is no possibility of replacement, there would be no other option but to completely dispose of the pH meter. However, thanks to the removable fiber junction of the electrode, the Hanna HI 98107 pH meter has a longer service life than other pH meters. This union is 2cm long and when it is contaminated or stops making effective measurements, we can replace it with a new one and thus extend the life of the electrode, and therefore that of the tester. In addition, all pH meters and instruments in the pHep series have a cap that protects the electrode. The calibration of the pH meter is carried out manually in 1 or 2 points with a potentiometer (included in the price) located on the side of the tester, thereby ensuring a measurement accuracy of ± 0.2 pH. The measurement is displayed directly on its large screen, which is visible from any angle. The pH meter works with a button cell whose consumption is minimal, ensuring an approximate autonomy of about 800h and thus avoiding having to replace it in a long time. The HI98107 precision + -0.1 pH meter is supplied with protective cap, calibration screwdriver, batteries, and instructions. Summary of main characteristics of the HI98107 pH meter: - Easy to use with only 2 buttons - Easy manual 1 or 2 point calibration - Renewable Union - Waterproof - Non-replaceable electrode Hanna precision pH meter applications: - Water analysis - Drinking water analysis - Aquariums - Pools and Spas - Personal care and health - Urine control - Saliva control
