Hanna - Tester TDS 4/Dist 4 Electrical Conductivity (EC) HI98304

Hanna Meters

Hanna is a brand specialized in the manufacture of chemical products and test for the control of swimming pool parameters. With all kinds of generic meters and specialized in specific parameters Hanna's catalog is undoubtedly the most complete on the market and the most specialized brand in the development of pool analyzers. 

Hanna HI98304

The EC Tester (0.00 to 19.99 mS/cm) DIST4 HI98304 is used to measure conductivity in drinking water, water conditioning, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquaculture and aquariums, hydroponics and printing industry.

It is a rugged, accurate meter that fits in a pants pocket, offering fast and accurate conductivity readings.

These meters feature a graphite amperometric electrode that provides better measurement repeatability since they do not rust. An amperometric EC/TDS measurement 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 the surface area which will affect the accuracy. The non-oxidizable graphite pins in DiST's are able to deliver an optimal surface for accurate and reliable results.

When calibration is required, simply dip the electrode tip into the calibration solution and adjust the potentiometer to the side of the meter.

An easily removable cap makes battery replacement simple. The battery life is about 250 hours of continuous use, so it is easy to guess that this change will be done not many times.

In summary, the main features are:

• Simple to use
• Hermetic
• Replaceable graphite electrode
• Temperature sensor
• Calibration is one point
