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

The HI-981074 portable Pool Line pH tester is designed to provide easily accessible pH and temperature readings for any pool, hot tub or spa owner and operator. Built with compact functionality in mind, this practical tester makes it effortless to gather readings from one or multiple pools or hot tubs on site, helping you to maintain high standards of safety and sanitation.

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.

HI-981074 features

100% waterproof

A fully waterproof casing plus a watertight seal on the battery compartment ensures this pH tester for pools and hot tubs remains in perfect condition in humid and wet environments. Even if you drop your tester into the water, it will float and remain fully functional and accurate for pH and temperature measurements time and time again.

Built-in exposed temperature sensor

An innovative exposed temperature sensor provides faster response times on readings, allowing you to gain insight into the temperature of your pool or hot tub as swiftly as possible. Automatic temperature-compensated measurements ensure the highest accuracy when testing your water.

Low battery indicator

The HI-981074 uses a 1.5V battery with approximately 800 hours of continuous use from a full battery charge. A low battery indicator offers insight into when your tester is due a new battery, ensuring the continuation of service with no delays.

Two-button operation

A simple, two-button operation makes it effortless to use this pH tester day-to-day, with no advanced learning or training required. Pressing only two buttons makes it as quick and easy as possible to get and record results from your tester.
