These compact, waterproof, pH meters feature advanced silicon chip pH sensors that give stable readings in seconds.  Only 5 ½” long, these meters fit right in your pocket.  Virtually unbreakable sensors eliminate the problems with delicate glass pH bulbs found on other pocket-sized pH meters.  Silicon chip sensors store dry and need no maintenance.  Clean up after dirty samples is easy with a toothbrush and detergent.

Use model IQ120 with convenient one-point calibration for routine pH testing. Both models have automatic temperature compensation for increased accuracy.

These are true permanent waterproof meters.  The reference is good for about 18 months to 2 years with daily use.  This turns out to be less than a penny per sample analyzed.
