Sper Scientific delivers dependable, accurate water quality measurement devices to monitor the changes in your water over time from seasonal variations, weather, as well as, manmade pollution. Whether you are in agriculture, aquaculture, industry, education, power generation, or municipal waste water, Sper Scientific offers you a complete line of water quality meters, to test the acidity, alkalinity, conductivity, dissolved oxygen (DO), Oxygen Reduction Potential (ORP), of your water.

Chlorine
Chlorine

Water chlorination is the process of adding chlorine (Cl2) to water as a method of water purification to make it fit for human consumption as drinking water. Sper Scientific offers Chlorine meters that meet the EPA method 330.5 for waste water and standard method 4500-CI G for drinking water and the ISO 7027 standards.
Conductivity / TDS / Salinity
Conductivity / TDS / Salinity

The amount of mineral and salt impurities in the water is called total dissolved solids (TDS). TDS shows how many units of impurities there are for one million units of water. One way to measure impurities in water is to measure the electric conductivity of water. Absolutely pure water is a poor conductor of electricity. Water shows significant conductivity when dissolved salts are present. Over most ranges, the amount of conductivity is directly proportional to the amount of salts dissolved in the water or Salinity. Four basic styles of Conductivity / TDS / Salinity meters are available for varying applications: Pens, Portable Meters, Data Loggers, and Benchtop meters.

Dissolved Oxygen
Dissolved Oxygen

Dissolved oxygen (DO) is one of the most important indicators of water quality. It is essential for the survival of fish and other aquatic organisms and is used in hydroponics as well. When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive. Sper Scientific dissolved oxygen meters are made to accommodate the user with rugged, portable meters for use out in the field. All of our DO meters offer fast and accurate DO response times in wastewater, surface water and aquaculture applications. Three basic styles of DO meters are available for varying applications: Pens, Portable Meters, and Multi-parameter meters.
Multi-Parameter
Multi-Parameter

Using different probes, these versatile meters monitoring different water quality parameters with the same meter. Three basic styles of multi-parameter meters available for varying applications: Portable Meters, Kits, and Benchtop meters.
pH/ ORP
pH

pH measures the acidity/alkalinity of a solution on a scale of 1 to 14 pH, with 1 being the most acidic and 14 being the most alkaline or basic. pH is a common measure of water quality used in environmental testing, food & beverages, cosmetics, pharmaceuticals and other fields. Four basic styles of pH meters are available for varying applications: Pens, Portable Meters, Data Loggers, and Benchtop meters. Click here for more information about pH.
Probes
Probes

Sper Scientific portfolio of probes provides the right solution for your testing needs, backed by years of product innovation and technical support. All of our probes are designed to meet the accuracy, ease of use, durability and flexibility for your water quality testing needs.
Test Strips Supplies & Kits
Test Strips Supplies & Kits

Sper Scientific offers the safest and most convenient delivery system for your DPD testing. All required reagents are precisely measured and impregnated on a test strip. These test strips allow the aqueous solution to pass back-and-forth through the impregnated chemical membrane. This unique design allows for the lowest sensitivity possible on a test strip.
Turbidity
Turbidity

Turbidity (undissolved solids) is an important measure of water quality in environmental testing, wastewater, petrochemical, beverage industry, and electroplating. Sper Scientific offers Turbidity meters that meet the EPA method 330.5 for waste water and standard method 4500-CI G for drinking water and the ISO 7027 standards.
