HI98311

Description

The HI98311 is an advanced, waterproof conductivity and TDS (ppm) tester for quick and easy measurements while on the go.

This lightweight, waterproof conductivity tester offers accurate conductivity (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature measurements in a single, portable, pocket device. No more switching between meters for your routine measurements.

• Compact & waterproof design fits right in your pocket so you can take it anywhere.
• Great for hydroponics, aquariums, pools, & ponds.
• Replaceable graphite electrode extends the life of your tester for years.

When the original DiST^® (Dissolved Solids Tester) was first introduced, conductivity and total dissolved solids measurements became easy and affordable. The DiST’s ease of use, in combination with its affordability, made it the standard in EC and TDS measurement. Hanna continues the standard in EC and TDS testing with the DiST®5.

This conductivity tester includes features such as a replaceable graphite electrode, adjustable TDS ratio, °C or °F measurement, Automatic Temperature Compensation (ATC) with adjustable β, battery level indicator, stability indicator, automatic shut-off and automatic calibration.

The graphite conductivity electrode offers greater accuracy by resisting contamination by salt deposits in the sample. All of these features are packed in a floating, waterproof casing. This 3-in-1 tester is unmatched in EC, TDS, and temperature measurements.

  Features at-a-glance:
•  Automatic Temperature Compensation
•  BEPS Alerts the user of low battery power that could adversely affect readings
• HOLD button to freeze readings on the display
•  Waterproof and designed to float
