HI-981004 Hot Tub and Pool pH Tester

The HI-981004 is a compact, practical way to easily measure the pH of water in hot tubs and swimming pools. This classic dip-and-test pH meter is an ideal cost-effective alternative to single-use testing strips, providing accurate results without relying on personal perception to determine the level of pH in your hot tub or pool.

Measuring pH is key to maintaining good sanitation in pools, hot tubs and spas. Changes in pH can change the effectiveness of chlorine, making this parameter the most important one to measure alongside free chlorine before you make adjustments to your water chemistry.

HI-981004 features

Exceptional accuracy

The HI-981004 features ±0.2 pH accuracy with 0.01 resolution, providing the precise results you need to correctly dose the water in your pool or hot tub. The accuracy of these results reduces the risk of over or underdosing the water, which can help to reduce the costs of pool maintenance.

Easy to read

A large, digital LCD provides clear readings from testing pH in pools. The screen also features other vital information for accurate testing, including a stability indicator and calibration tags. A battery indicator is also included to see how much power this hot tub tester has left at a glance.

Automatic calibration

Using Hanna’s simple buffer solution sachets, you can calibrate the HI-981004 pool meter to one or two points. Calibration buffers are automatically recognised by the tester to streamline the process, saving time and ensuring long-term accuracy when measuring pH in hot tub or pool water.

Long battery life

This pocket tester has a battery life of approximately 1000 hours. When the battery power is running low, a battery indicator is displayed on the screen. The HI-981004 uses 1.5V CR2032 batteries that are easily replaceable and features an auto-shut-off functionality to further save battery life.

Case included

The HI-981004 includes a hard-wearing plastic carrying case for easy transport and practical day-to-day storage. The meter, probe, calibration solutions, and cleaning solutions are all packaged in this durable plastic carrying case in the box.

Replaceable pH electrode

This pool pH tester is supplied with the HI-1271 pH electrode. This electrode is 103 mm long and tapers to an 8 mm diameter at the sensing end to easily fit into test tubes, vials, and other containers with small openings and can be replaced as required to further extend the lifespan of this tester.

Achieve HSG282 compliance 

The HI-981004 is an ideal option to comply with the HSE’s 2017 HSG282 legislation for hot tubs and spa pools. These guidelines provide clear information to help you protect your business and your customers from harmful pathogens found in unclean or unbalanced agitated warm water.

As one of the primary requirements for HSG282, this Pool Line checker is an ideal choice for fast, compliant HSG282 pH readings twice daily. Simplicity is one of the key benefits of choosing Hanna Instruments pH testers for HSG282.

FAQs

How does a hot tub pH tester work?

Digital pH testers for hot tubs and swimming pools have an electrode that reads the level of pH within the water. This number is then displayed on the screen, allowing you to make precise adjustments to your water chemistry to make it safe for use. Learn more about how hot tub testing can help to prevent diseases in our article here.

Do I need a pH tester for hot tubs or pools?

pH is a vital parameter to measure in pools and hot tubs. Using a digital pool tester provides a clear insight into whether the pH is in the right range. This information is vital for balancing the water chemistry, as pH that is outside of the typical range has a direct impact on the effectiveness of chlorine. Learn more about why pH testing is important here.

What should the pH range be for my pool?

The typical ideal pH range for most pools is between 7.2 and 7.6. This range provides the best conditions for sanitation, helping to keep the water clean and safe for use. Before chlorine is introduced to the water, it’s important to take a pH measurement and ensure this parameter is in the right range. Checking the pH in pools first reduces chemical wastage and prevents the need for remediation. Learn more about the parameter ranges for pools here.
