"Complete Meter Stick Optics Bench"

Designed to measure conductivity in water analysis, biology, chromatography, food, electronics, dairies, and PC-board rinsing, the conductivity meter provides results in conductivity (micromhos/cm and microsiemens/cm), resistivity (megohms), and dissolved solids (parts per million).

Units have instant-response probe and solid-state thermistor for quick, precise readings.

Accurate answers in five seconds with a meter that automatically selects proper range and displays the exact answer.

This pH tester is ideal for wastewater, water quality and environmental applications. Compact, water resistant (IP67) instrument fits into the palm of your hand.

This user-friendly meter has a long battery life and plenty of helpful functions.

Store Up to 15 Readings

Lightweight, Versatile Unit

Designed for direct measurement.

This pH tester is sleek tester is accurate to 0.1 pH with a built-in thermometer to automatically adjust the pH reading for temperature. The waterproof design (it floats), simple operation, and replaceable electrode mean that you can rely on this meter for years. The large LCD display shows both pH and temperature readings simultaneously, while a stability indicator is displayed to alert you when a stable reading has been obtained.

The pHep®5 is an advanced, waterproof pH and temperature tester with 0.01 resolution that makes measuring quick and easy. This accurate pH tester features 0.01 resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device. No more switching between meters for your routine measurements.

This multiparametrer tester is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off.

Simple read out.

This convenient device measures dissolved oxygen concentration, saturation, and temperature - all in one!

Since you can refill the ExStik® quickly, you won't need to worry about the shelf life of its electrode.

Flat electrode surface allows pH readings in liquid flms, semi-solids, and solids.

Easy to carry, simple to operate and sufficient for most field pH tests.
