ExStik II Waterproof pH/Conductivity Meter, IP57

The ExStik II Waterproof pH/Conductivity Meter (Model EC500) is a versatile instrument that measures five key water quality parameters using a single electrode: Conductivity, TDS, Salinity, pH, and Temperature. With a high-accuracy, multi-ranging sensor, this meter provides reliable results for a wide range of applications.

The large LCD features an analogue bargraph that indicates trends at a glance, while the memory function stores up to 25 labelled readings for easy record keeping. The conductivity-to-TDS ratio is adjustable from 0.4 to 1.0, with a fixed 0.5 salinity ratio, allowing flexibility across different water types. The RENEW feature alerts you when the electrode needs replacement, ensuring consistent performance over time.

This waterproof meter (IP57 rating) is supplied complete with the meter and electrode, protective cap, sample cup, four CR-2032 batteries, and a 1.2m neckstrap for convenient portability. It includes an auto power-off function that can be disabled, making it suitable for both short tests and extended monitoring sessions.

Measurement Capabilities:

• Conductivity: 0 to 19.99 mS/cm
• TDS: up to 999 ppm
• Salinity: up to 999 ppm
• Temperature: -5°C to +90°C
• Units: pH, µS/cm, mS/cm, ppm, ppt, mg/L, g/L, °C, °F

Ideal for water quality testing in environmental, educational, or industrial settings, the ExStik II combines durability, accuracy, and ease of use. Its waterproof design ensures dependable operation even in damp or splash-prone environments.
