## Overview

The Extech EC150 is a professional-grade Conductivity/TDS/Temperature Meter offering ±1% accuracy and fine resolution for conductivity (up to 19.99 mS/cm), TDS (up to 19.99 ppt), and temperature (0-50°C). Its IP65 waterproof design, large LCD, and customizable calibration ratio make it ideal for environmental monitoring and industrial applications, backed by a 2-year warranty.

## Description

The EC150 is a Conductivity/TDS/Temperature Meter. Waterproof meter with high-accuracy multi-ranging sensor. Features Auto Power off with disable, Adjustable Conductivity to TDS ratio factor from 0.4 to 1.0, Data Hold and low battery indication. Waterproof design to withstand wet environment, meets IP65 standard. Includes meter, protective sensor cap, and four LR44 button batteries.

Review: Excellent for monitoring freshwater stream water quality - I do monthly stream water quality monitoring using a very expensive YSI DSS Pro probe system. A county agency maintains and calibrates it. But in the winter I like to do more frequent monitoring of conductivity so I can track excessive use of road salt. I have been using an EC100, but needed a second for a friend. The EC150 adds total dissolved solids to basic conductivity. I do not use TDS but the EC150 tends to be easier to find on desertcart, and I just leave it set on conductivity. There are cheaper conductivity meters, around $10. They are pure junk. These Extech ECs have proper temperature compensation and are very linear. Their readings match those of the expensive YSI probe within a couple of microSiemens, and they hold calibration quite well (as long as the batteries are good). I check calibration each time I take them out, using 1000 microSiemen calibration fluid. The only time I've had bad readings was when the EC100's batteries were weak.

## Features

- Measures conductivity (0-1999 µS/cm and 0-19.99 mS/cm) with ±1% full-scale accuracy and 1 µS/cm resolution
- Measures TDS (0-1999 ppm and 0-19.99 ppt) with ±1% accuracy and 1 ppm resolution
- Measures temperature from 0 to 50 °C (32-122 °F) with ±1 °C (± 0.9 °F) accuracy and 0.1 °C resolution
- Waterproof housing compliant with IP65 rating; features auto power-off (with disable), data hold, low-battery indicator, and adjustable Conductivity-to-TDS ratio (0.4-1.0)
- Large 3½-digit (2000-count) LCD display; includes protective sensor cap and four LR44 button batteries in the package

## Questions & Answers

**Q: Just to be sure, this will detect salinity fluctuations of coastal marine water (35 ppt)?!**
A: The max salinity for this meter is 9.99g/L  (parts per thousand).  So if you know the water is in the range of 35ppt, you can't make direct measurements.  But, you could dilute the sample (say 10x) in the field using bottled water (has a salinity <<< sample) or DI water and that would put you at 3.5g/L roughly.  You should be able to detect fluctuations at 0.1ppt on the diluted water which translates into detecting 1ppt fluctuations in the water.

**Q: is the Exstick EC500 come with calibration certificate ?**
A: No, it does not, but we can get you a Certificate of Conformance from Extech, when you purchase this product from our Amazon Store.

**Q: how does it give two readings**
A: Salinity in ppm   Conductivity.  And total dissolved solids. I really like this meter. Used it for jar tests this summer

**Q: Can this be used in soil?**
A: Hi This product can not be used in soil.
