TOUGH. LAB GRADE. PRO STANDARD.
MW302 is a portable wide range conductivity (EC) meter with automatic temperature compensation. This instrument is designed to meet the needs of growers for equipment suitable for the aggressive environments found in agricultural and hydroponic applications.
The MW302 has a range of 0.0 to 10.0 mS/cm with a resolution of 0.1 mS/cm. This EC meter comes complete with conductivity probe with 1 m (3.3') cable and calibration solution.
DESIGN FEATURES
- 0.0 to 10.0 mS/cm range.
- Fast, easy to read results with large digital LCD readout.
- Supplied with conductivity probe attached to a 3 foot long cable.
- Accuracy to ±2% FS @ 25°C.
- Lightweight and portable.
- 300 hours battery life with continuous use (battery included).
- SE520 Conductivity Probe (included).
- Starting calibration solution MI0031B, 1413 uS/cm (included).
USE AND MAINTENANCE
EC electrodes may start to release nutrients over time. Rinse the probe with fresh tap water after each use to prevent build-up.
CONVERTING EC TO TDS
The Milwaukee EC pen, like all conductivity meters, provides a measurement of electrically charged ions in a solution and is an absolute measurement of conductivity.
EC is often converted to TDS in parts per million (ppm). There are several scales, such as the 500 scale, the 650 scale, and the 700 scale. However, the true PPM can only be determined by chemical analysis.
Your mS/cm reading can be converted to TDS (ppm) by approximation:
2,000 µS/cm = 2.0 mS/cm = 1000 ppm on .50 factor scale
2,000 µS/cm = 2.0 mS/cm = 1400 ppm on 442 scale or .70 factor scale
