Very handy and accurate ### ⭐⭐⭐⭐ 4.0 out of 5 stars Good Product at great price *by A***R on Reviewed in India on 10 February 2019* Good product for measuring EC of water. Accuracy is enough for rough measurements. Haven't cross checked yet. Anyway, I got it for less than 600, which is a great price as well. ### ⭐⭐⭐ 3.0 out of 5 stars EC reading doubtful *by D***A on Reviewed in India on 4 December 2019* Got this product yesterday. I bought it mainly for EC. Though TDS of water shown is correct but corresponding EC value is in hundreds which should be in decimals. The decimal is missing in the reading. Can company clarify this? ## Frequently Bought Together - JEEJEX Plastic Portable Multifunctional 3-in-1 Tds Ec, Temperature Monitor Water Quality Tester Pen with Large Display Screen - GRANOTONE Acrylic Artist's Varnish Non Yellowing Non Toxic (200 ML MATT) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/89720795-jeejex-plastic-portable-multifunctional-3-in-1-tds-ec-temperature](https://www.desertcart.pe/products/89720795-jeejex-plastic-portable-multifunctional-3-in-1-tds-ec-temperature) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-19*
