These products are currently being re-engineered and will not be available until May/June 2011
The IQ120 and IQ125 compact, waterproof non-glass pH meters are not designed to be disposable- they are designed to last.
They feature advanced ISFET silicon chip pH sensors that provide stable readings in seconds. Only 5 1⁄2" long, these ISFET meters fit right into your pocket. The virtually unbreakable ISFET sensors eliminate the problems of delicate glass sensors that are found on other pocket-sized pH meters.
The silicon chip ISFET sensors store dry and need no maintenance. A toothbrush and detergent are all you need to clean dirty sensor surfaces. Use the Model IQ120 pH meter with convenient one-point calibration for routine pH testing. The Model IQ125 Professional pH meter features automatic buffer recognition and one-point, two-point or three-point calibration for high accuracy over a wide range of pH values.
Both pH meter models have automatic temperature compensation. The miniLab pocket-sized pH meters come with two replaceable watch batteries that provide over 200 hours of use. An automatic power off feature conserves energy and error messages alert you to a low battery condition or incorrect calibration. Other features include a replaceable reference electrode, retention of calibration after shutoff and the ability to measure samples as small as a single drop.
