Review: Useful, accurate and easy to use - I use this to do spot water quality tests on the water coming from the private well that feeds my home. For the most part, it's easy to use and is as accurate as any tests I've tried. TDS, Salinity, ph and conductivity are easily determined from a single test sample in under five minutes. Of course, it would be ideal is the unit could also test for additional contaminants (iron, nitrates, chlorine, etc), but for what it offers, this is a great probe that gives you a quick understanding of whether you've had any changes to your water quality. Definitely a good way to get started with water quality testing. Review: Buena compra - ¡Funciona perfecto! Lo volvería a comprar. ## Features - Combination flat surface pH electrode with auto ranging high accuracy conductivity cell - Measures 5 parameters including conductivity, TDS, salinity, pH, and temperature using one electrode - 9 units of measure: pH, µS/cm, mS/cm, ppm, ppt, mg/L, g/L, Celsius, Fahrenheit - Analog bargraph indicates trends - Memory stores up to 25 labeled readings ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Extech | | Global Trade Identification Number | 00793950055007 | | Item Weight | 0.11 Kilograms | | Item dimensions L x W x H | 1.1 x 1.9 x 4.5 inches | | Material | Acrylonitrile Butadiene Styrene (ABS) | | UPC | 793950055007 | ## Product Details - **Brand:** Extech - **Material:** Acrylonitrile Butadiene Styrene (ABS) - **Item dimensions L x W x H:** 1.1 x 1.9 x 4.5 inches - **Item Weight:** 0.11 Kilograms - **UPC:** 793950055007 ## Images ![EC500 Waterproof ExStik II pH/Conductivity Meter - Image 1](https://m.media-amazon.com/images/I/51WqlZVlK3L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Useful, accurate and easy to use *by B***E on April 20, 2015* I use this to do spot water quality tests on the water coming from the private well that feeds my home.

Lo volvería a comprar. ### ⭐⭐⭐⭐⭐ Good little meter. *by M***E on January 5, 2022* Easy to calibrate with known lab grade pH cal standards. 4,7,10. Compared this meter to lab a grade Hach ph meter and the readings were spot on after calibration. Comes with a sponge in the cap and a little sample cup that allows the meter to sit in the solution being measured. ## Frequently Bought Together - Extech EC500 Waterproof ExStik II pH/Conductivity Meter - pH Buffer Calibration Solution Kit 3-Pack: pH 4.00, pH 7.00, pH 10.00 Buffers — 250 ml (8.4 fl oz) Each — Color Coded — NIST Traceable for All pH Meters - Oakton AO-00653-18 Oakton Conductivity and TDS Standard, 1413 Μs; 500 mL --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/7003674-ec500-waterproof-exstik-ii-ph-conductivity-meter](https://www.desertcart.tn/products/7003674-ec500-waterproof-exstik-ii-ph-conductivity-meter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-07*
