SimplexHealth Total Hardness test strips are perfect to test the hardness of your water, to check the performance of your water softener, for service work, classroom demonstrations, or to give to customers instead of an expensive service call. This full range test kit lets you measure hardness on a very wide range of 0ppm to 1000ppm (mg/l).

(ppm = parts per million)

The definition of water hardness is based on the amount of calcium it contains per litre:

  • Soft water contains less than 30mg of calcium per litre (less than 30ppm)
  • Moderately hard water contains between 30 and 60mg (30 to 60ppm)
  • Hard water between 60 and 120mg (60 to 120ppm)
  • Very hard water contains more than 120mg of calcium per litre (more than 120ppm)

Total Hardness test strips for water quality offer a wide range of detection and are calibrated to be both accurate and sensitive:

  • Simple Dip-Wait-Read Testing Method
  • Low cost and high accuracy
  • Test strips are stored in a plastic container to protect them
  • Ideal for quick and reliable testing of water
  • Accurate results are achieved less than one minute
  • This product is safe and easy to use since there are no chemicals to mix, an MSDS is not required

With total hardness water quality test strips you are in control and can find out exactly where your calcium level is before it becomes a problem.

Understanding your Results:

  • Hardness greater than 80ppm: Detergents with softening agents are not completely effective in cleaning
  • Hardness greater than 120ppm: Some scaling will occur in pipes and appliances
  • Hardness greater than 250ppm: Dishwasher impossible to use without producing film on dishes

Simple, logical and so very easy to use. The test kit is a very helpful product to use when occasionally checking the effectiveness of my water softener. So much so that it recently indicated that the water was too hard and after adjusting the softener it returned to its original state of agreeable softness.

These test strips are easy to use and are definitely 100% reliable. I've been using them to test the hardness of drinking for several years and have repeat purchased them many times. I live in a motorhome and travel a small amount and have found that in some parts of Europe the water is very hard and furs up the plumbing and the hot water boiler. I have a portable water softener which needs a simple service as it's performance falls off. These strips allow me to see when it's needed. They are excellent.

During the time I've been using the strips I've also bought a few of the electronic ones. I've as of yet not found an electronic one that could give me anything like a reliable result. The three I've bought have been completely useless for my task.

Excellent tests strips. They are really quick and easy to use to tell whether your water softener is working. The only negative is that the colours are slightly blurry and make it difficult to tell the exact measurement but as a qualitative test it is clear and therefore gets 4 stars from me.

Very pleased with the product. I can confirm that the strips are easy to use & they have confirmed my belief that my water is hard.

I find that this product is very handy for when I'm visiting potential clients and checking their water supplies before selling them a Commercial Dishwasher or Glasswasher or any other Catering appliance that has a water feed.
