Extech Instruments Pocket Conductivity TDS and Temperature Meter

The Extech Instruments Pocket Conductivity, TDS and Temperature Meter is a versatile and waterproof handheld device designed for accurate measurements in demanding environments. Equipped with a single high-accuracy, multi-ranging sensor, this meter measures conductivity, TDS (Total Dissolved Solids), and temperature simultaneously, providing comprehensive water quality analysis in one convenient tool.

Featuring an adjustable conductivity-to-TDS ratio factor (from 0.4 to 1.0), the meter conveniently calculates TDS values to suit various water types. It offers two conductivity/TDS ranges with one-point calibration per range, ensuring dependable readings across different applications. The clear 3½-digit (2000-count) LCD displays conductivity or TDS along with temperature, and supports units including μS/cm, mS/cm, ppm, ppt, °F, and °C.

Designed for practical use, the meter includes a Data Hold function and low battery indication, an Auto Power Off feature that can be disabled, and adjustable Automatic Temperature Compensation (ATC) for consistent results. With an IP65 waterproof rating, it reliably withstands wet conditions. The unit comes complete with a protective sensor cap and four LR44 button batteries.

Weighing only 120 g and with compact dimensions of 43 mm × 33 mm × 15 mm, this meter is portable and easy to carry. Its professional accuracy and robust design make it an essential tool for water quality monitoring.
