ExStik® Waterproof Series PH100 Pen Type pH Meter RE300 Pen Type ORP Meter User’s Guide
Welcome you to buy the waterproof series of PH100 pH meter and RE300 ORP meter (hereafter call meter) from Shanghai San-Xin Instrumentation, Inc. The electronic unit is made by the EXTECH Instruments Corp. in the U.S.A.
pH is a unit of measure (ranging from 0 to 14pH) indicating the degree of acidity or alkalinity of a solution. pH tests are the most commonly performed measurements in water analysis, using the hydrogen ion activity of a solution to determine acidity or alkalinity. Solutions with a pH less than 7 are considered acidic, solutions with a pH higher than 7 are known as alkaline, and solutions with a pH of exactly 7 are considered neutral. It needs to measure pH value in great many fields such as industrial, agriculture, physic, environmental protecting and scientific research etc.
ORP is an abbreviation of “Oxidation-Reduction Potential”, which means the oxidation-reduction potential of solution, ORP value is a measuring index reflects the oxidation-reduction ability of water solution, its units is mV. At present, its application becomes more and more common in processing of waste water.
This meter adopts flat surface pH and ORP combination electrode, there is a microprocessor chip inside the meter and the appearance looks smart as well as easily operation. For notable features read as follows:
●Adopt flat surface pH electrode can be used in any solution, micro-solution (min. 0.3mL) half-solid and solid with water such as skin, meat, fruit, cloth, paper, rug and cheese etc.
●Large LCD with Bargraph.
●Automatic temperature compensation when pH test and can display pH value and temperature at the same time.
●There is a microprocessor inside meter, have functions of automatically calibration, data memory, calibration indicator, automatically recognize electrode, electrode invalidation display, low battery indication and auto power OFF etc.
●One meter can be equipped with pH, ORP and chlorine electrode, and automatically recognizing, auto display different units icons.
●Replacing electrode is convenient, which can limitless extend life of meter.
●Reliable waterproof design can be used in any moisture and water condition.
●Special casing and equips with all accessories makes use to be more convenient.
This meter can be used in measuring pH and ORP value by industrial, agriculture, physic, environmental protecting, scientific research and water processing project etc.
