Water Hardness Test Strips 0-180 ppm

Lamotte 2981 test strips measure water hardness from 0 to 180 ppm using a simple dip-and-read method. Each pack contains 50 strips and includes a colour chart label for immediate comparison. The strips are 3 in long and 1/4 in wide, designed for quick field checks. They suit technicians, facility managers and homeowners who need fast hardness verification.

Dry Storage and Single-Use Operation

The strips require no power, produce no noise and generate no heat during use. Each strip is consumed after one test, so ongoing cost scales with the number of measurements. Storing the bottle in a cool, dry place preserves reagent accuracy between uses. No calibration or warm-up time is needed before testing.

Portable Bottle With Integrated Colour Chart

The 50-strip bottle fits in a tool bag or pocket and the colour chart is printed on the label, eliminating loose reference cards. Strips are protected from moisture until the cap is opened, supporting reliable results over multiple sessions. Users who need higher resolution, automated logging or parameters beyond hardness will require a different instrument.

Questions about this item

How do I use the Lamotte 2981 test strips and what is the common mistake?

Dip a strip into the water sample, remove immediately, and compare the colour to the chart on the label within the specified time; the frequent error is waiting too long before reading, which shifts the colour and gives a false hardness result.

What will need replacement after the 50 strips in this pack are used?

The pack contains 50 single-use strips; once they are exhausted you must purchase a new pack of Lamotte 2981 strips to continue testing hardness.

What is the highest hardness level these strips can measure before they stop giving a distinct reading?

The strips cover 0 to 180 ppm hardness; samples above 180 ppm will exceed the colour chart range and cannot be accurately determined with this product.
