Extech EC700 6-in-1 Water Quality Meter
The Extech EC700 gives fast and clear water testing in one handheld unit. It measures six key values at once and shows them on a large LCD screen for easy viewing.
You can check pH, conductivity, TDS, salinity, dissolved oxygen and temperature with ease. As a result, field teams save time and reduce the need for multiple tools.
Reliable field performance
The Extech EC700 works well in tough sites thanks to its IP67 rated case. It resists water and dust, so you can trust it in outdoor or wet conditions.
In addition, the optical dissolved oxygen probe needs no minimum flow. This helps deliver stable readings while reducing maintenance needs over time.
Simple workflow and data tracking
The device stores up to 99 readings, which helps track trends and record results. Therefore, users can review past data without extra tools.
Built-in compensation for temperature, pressure and salinity improves accuracy. The Extech EC700 ensures results stay reliable even when conditions change.
