Portable, waterproof pH tester for swimming pools, hot tubs and spas

The simple-to-use nature of the HI-981074 makes taking readings and recording them effortless.

As part of our Pool Line range, the HI-981074 fully complies with HSG282 guidelines, helping you maintain high safety standards for your guests and employees on-site. Calibrate using our buffer solution, take your temperature and pH reading, and make any adjustments needed to maintain optimal sanitation and hygiene standards.
