Fast. Reliable. Precise. Insta-TEST® Monopersulfate (MPS), Alkalinity, pH Test Strips from LaMotte Pacific

28, Jul 2025

When water quality matters, speed and simplicity are everything. Whether you’re maintaining a spa, using a pool test kit in Australia, or testing other water systems, reliable chemistry should never slow you down. That’s where the Insta-TEST® Monopersulfate (MPS), Alkalinity, and pH Test Strips from LaMotte Pacific come into play — delivering instant, lab-accurate results with zero fuss.

Let’s dive deep into why these swimming pool test kits in Australia are becoming a must-have in every water technician’s toolkit.

What Are Insta-TEST® MPS, Alkalinity, and pH Strips?

The Insta-TEST® line is built for quick, easy, and accurate water testing. This particular triple-parameter strip lets you measure:

  •  Monopersulfate (MPS) — with visual indicators for Low, OK, and High ranges.
  •  Total Alkalinity — at 0, 40, 80, 120, 180, and 240 ppm.
  •  pH Levels — at 6.2, 6.8, 7.2, 7.8, 8.4, and 9.0.

Just dip the strip, wait a few seconds, and compare the colors — no reagents, no timers, no errors.

Why Test for These Three Parameters?

Each of these water parameters plays a vital role in maintaining balanced and safe water chemistry.

1. Monopersulfate (MPS)

MPS is a non-chlorine oxidizer used in pools and spas to break down organic contaminants. While it’s a great alternative to chlorine shock treatments, overdosing MPS can lead to eye and skin irritation, while underdosing renders it ineffective. That’s why knowing whether your MPS levels are low, okay, or high matters.

2. Alkalinity

Alkalinity acts as a buffer for pH, preventing sudden spikes or drops. Low alkalinity can cause pH fluctuations, corrosion, and eye irritation. High alkalinity makes it harder to adjust pH and can cause cloudy water and scale formation.

3. pH

Ideal pH for pool and spa water sits between 7.2 and 7.8. Outside of this range, you’re looking at corrosion, skin discomfort, equipment damage, and decreased sanitizer effectiveness.

Testing all three gives a 360° view of water stability  and this test strip delivers all three in a single dip.

What Makes These Strips Stand Out?

Here’s why LaMotte’s Insta-TEST® is leagues ahead of the average strip:

Dip-and-Read Convenience

No mixing. No shaking. Just dip and compare. Results appear instantly, so you’re not left guessing or waiting.

Broad Testing Range

From low-end MPS to high-range alkalinity and pH, these strips are designed for diverse water types and treatment scenarios.

Tough, Waterproof Packaging

Each bottle contains 50 test strips, housed in a PopTop bottle with a molded desiccant liner. This isn’t just good design — it’s protection against moisture, humidity, and UV exposure, ensuring your strips stay effective longer.

Color Chart Printed On the Bottle

The reference color chart is easy to read and always within reach right on the label. No manual? No problem.

Who Uses These Strips?

These test strips are a go-to for:

  •  Spa and Pool Technicians
  •  Facility Managers
  •  Hospitality Industry Professionals
  •  Homeowners with Pools/Spas
  • Water Treatment Specialists

Anywhere that clean, balanced water is critical  these strips are up to the task.

How to Use

Step 1: Dip the strip into the water sample for 2 seconds.
Step 2: Remove the strip and shake off excess water.
Step 3: Wait 15–30 seconds (per LaMotte’s recommendation).
Step 4: Compare each test pad to the chart on the bottle. Done!

No batteries, no calibration, no chemistry degree needed.

When to Test?

  • Daily or Weekly for spas and pools
  • After shocking with MPS
  • After heavy use or rainfall
  • When troubleshooting water issues

Consistent testing helps prevent problems before they escalate  and saves money on chemical corrections.

Final Thoughts

The Insta-TEST® Monopersulfate (MPS), Alkalinity, and pH Test Strips are more than just convenient — they’re a critical control tool for anyone managing water quality. Built with precision, protected against the elements, and designed for real-world ease — this test strip is the tiny lab that fits in your pocket.
