This tester is an advanced, waterproof conductivity and TDS (ppm) tester for quick and easy measurements while on the go. This lightweight, waterproof conductivity tester offers accurate conductivity (0 to 3999 µs/cm), TDS (0 to 2000 ppm), and temperature measurements in a single, portable, pocket device. No more switching between meters for your routine measurements.

This pH tester is an easy-to-use pH water tester that makes monitoring water quality simple. This accurate pH tester features 0.1 resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device.

It is a set of premium quality 1.413 µs/cm conductivity standards and pH 7.01 buffers that are NIST traceable and contained in portable single-use sachets. Each sachet has the lot number and expiration date stamped on it and is made of light block foil ensuring freshness each time one is opened. Hanna's line of conductivity solutions and pH buffers have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened sachet. This package of calibration sachets are for 20 sachets (10 each) containing 20 ml of solution.

This general purpose cleaning solution can be used for a variety of applications. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna's cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction.
