Hanna Instruments HI98304 conductivity meter DiST 4

DiST 4 pocket-sized conductivity tester, up to 19.99 mS/cm. DiST® testers are widely used for monitoring conductivity in drinking water, water treatment, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquariums, hydroponics, and the graphics industry. These testers feature an amperometric graphite electrode that ensures improved measurement repeatability because it does not oxidize.

• Dist 4 pocket-sized conductivity tester, up to 19.99 mS/cm.
• Simply immerse the electrode tip in the calibration solution and the meter calibrates automatically.
• Widely used for monitoring conductivity in liquids.
• Water-resistant meter.
• Automatic temperature compensation (ATC).
• Automatic single-point calibration.
• Measurement stability indicator.
• Exposed temperature sensors for faster response times.
• An easily removable cover provides access to the battery compartment.

An amperometric measurement of EC is based on Ohm's law: I = V/R, where R depends on the distance between two pins and their surface area. Oxidation changes both the distance and the surface area, which directly affects accuracy. DiST® non-oxidizing graphite tips can provide an optimal surface for accurate, reliable results.

Automatic calibration
When calibration is required, simply immerse the electrode tip in the calibration solution and the meter calibrates automatically!

Exposed temperature sensor
These testers feature exposed temperature sensors for faster response times.

Water-resistant
An easily removable cover provides access to the battery compartment.
