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.

Heat Stress
-
Our lineup of heat stress meters include the WBGT (Wet Bulb Globe Temperature) meters, which provides the most accurate determination of the heat stress index based on the cumulative effect of air temperature, air movement, relative humidity, and radiant heat.

Chlorine Meters
-
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 standard method 4500-CI G for drinking water and the ISO 7027 standards.

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.

ORP Meters
-
ORP (Oxidation Reduction Potential) measures a system’s relative state for gaining or losing electrons. ORP values are affected by all oxidizing and reducing agents, not just acids and bases that influence pH measurement. In practice, ORP measures the ability of a lake or river to break down waste products, like contaminants and organic matter. When the ORP value is high, there is lots of oxygen present in the water.

Refractometers
-
Sper Scientific sells four main refractometer types: Optical Refractometers, Digital Handheld Refractometers, Waterproof Refractometers and Desktop or Laboratory Refractometers. Industries that use our refractometers include: Pharmaceutical, Chemical, Petroleum, Petro-Chemical, and Food & Beverage industries. Our refractometers measure items such as: honey, Brix or sugar content of a liquid, salinity or salt content of a liquid, battery coolant, and urine.
