Hanna DiST 5 Waterproof Tester
The original DiST (Dissolved Solids Tester) was first introduced in 1986 by HANNA®. Since then, Conductivity and Total Dissolved Solids measurements have never been easier. DiST’s ease-of-use, in combination with its affordability, made it the standard in EC and TDS measurement. HANNA® continues the tradition of innovation with the DiST 5. For this series, we have included all the features you have asked for and more!
The DiST 5 Waterproof 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 provides greater accuracy because it resists 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/ temperature measurements.
- Dual-level LCD
- Replaceable graphite electrode cartridge
- Automatic calibration
- Waterproof — it floats
- High accuracy
- Automatic calibration and temperature compensation
- HOLD function
- BEPS (Battery Error Prevention System)
- Includes probe, probe removal tool, batteries, and instructions
Frequently Asked Questions:
|Q:||Why are PPM, TDS, pH and EC important?|
|A:||PPM and TDS are abbreviations that represent the concentration of elements in a solution or atmosphere. PPM is short for parts per million and TDS for total dissolved solids. EC (electro conductivity) is another form of measurement for TDS. PH is a measure of acidity or alkalinity which dictates plant uptake of particular elements.|
|Q:||My pH meter doesn’t hold calibration. How often should I recalibrate it?|
|A:||pH meters do need to be calibrated by the user every day since the membrane does change and is affected by the temperature as well. If pH values are very critical then it will need to be recalibrated several times a day, or before each sample test (depending on how critical the value is). Uncontaminated calibration solution is very important as well. For each calibration, pour some solution in a separate container. Keep out of sunlight and away from heat.|
|Q:||What is the suggested pH range for my hydroponic system and soil plants?|
|A:||Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption. Maintain a pH between 5.0 and 6.5 for hydroponic gardens and 6.0 to 7.0 for soil applications.|
