Description and Overview 

DiSTs are rugged and reliable pocket-sized testers that offer quick and accurate readings of conductivity or TDS. The DiST family of testers is widely used for monitoring EC/TDS in drinking water, water conditioning, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquaculture and aquariums, hydroponics, and the printing industry.

This tester features an amperometric graphite electrode that provides better repeatability in measurements since they do not oxidize. An amperometric measurement of TDS is based on Ohm’s Law, I = V/R where R depends on the distance between two pins and their surface. Oxidation changes both the distance and surface, which will affect accuracy. The DiST’s non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results.

When calibration is necessary, simply submerge the electrode tip into calibration solution and adjust the trimmer on the side of the tester.

  • Automatic temperature compensation
  • Easy-to-use and inexpensive
  • Graphite electrodes
  • Comes with protective cap, screwdriver, batteries, and instructions

Hanna Instruments Meters & Testers

In 1978 Hanna Instruments was founded in Limena, Italy by Oscar and Anna Nardo. Since that time, Hanna Instruments has grown to be a worldwide leader in the development of electro-analytical instrumentation. The development of novel instrumentation for customers that would not have normally used instrumentation is what has led to the success of the company.

In the 80’s the company had a mission to provide a pH meter that was affordable, accurate and easy to use. The result was the pHep (pH electronic paper). This meter used an integrated circuit to measure the voltage response of a pH electrode packaged into a pocket-sized meter. The calibration of the meter was performed manually and the price was less than $50.00. Having a simple operation and very affordable price point brought the advantages of an electro-analytical measurement of pH to the masses. Whether it be a farmer looking to measure the pH of soil to the printing press operator that needs to measure the pH of a fountain solution. Hanna Instruments provided the user with an accurate electronic alternative to litmus paper and chemical indicators.

Hanna Instruments has a history of developing innovative products that make analytical measurements easier to perform at an affordable price. Many innovations introduced by Hanna are now the norm for the instrumentation industry.
