Name: Extech EC500 pH/Conductivity/Temperature Meter
SKU: 240744

The Extech EC500 ExStik II is a versatile and waterproof meter that accurately measures five essential parameters: Conductivity, TDS, Salinity, pH, and Temperature—all with a single electrode. Designed for both convenience and performance, this meter features a high-accuracy multi-ranging sensor and an analog bar graph display for real-time trend visualization.

Ideal for laboratory, environmental, and industrial applications, the EC500 includes memory storage for up to 25 labeled readings and incorporates a RENEW feature to notify users when the electrode needs replacement. The meter also supports automatic power-off functionality, which can be disabled as needed.

What's Included:

1 - Meter Electrode
1 - Protective Cap
1 - Sample Cup
4 - 3V Cr-2032 Batteries
1 - 48" (1.2M) Neckstrap
