Extech Instruments meters keep track of pH in concrete

Extech’s meters measure pH in liquids, semisolids and solids. They are the only stick-style pH meters with flat surface electrodes, and they feature a digital readout with an analog bargraph displayed on an LCD. Renew indicators monitor calibration and tell the user when to replace the electrodes.

The PH100 and PH110 do 1-point, 2-point and 3-point calibrations, recall up to 15 labeled readings, display pH and temperature simultaneously, and provide automatic temperature compensations. Each meter is waterproof and comes with a flat surface pH electrode, a protective sensor cap, a sample cup with cap, four SR44 button batteries and a 48-inch neck strap.
