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 resealale bag 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

Suitable for: fresh water samples, including water from taps, wells, springs, boreholes, ponds, as well as rain water
