ORPTestr 10 Pocket ORP Tester
Oxidation-Reduction Potential (ORP) or Redox potential measurements are used to monitor chemical reactions, to quantify ion activity, or to determine the oxidizing or reducing properties of a solution. ORP is a measurement of the electrical potential of a redox reaction and serves as a yardstick to judge how much oxidation or reduction takes place under existing conditions.
ORP electrodes measure the voltage across a circuit formed by the measuring metal half cell and the reference half cell. When the ORP electrode is placed in the presence of oxidizing or reducing agents, electrons are constantly transferred back and forth on its measuring surface, generating a tiny voltage. The ORP measurement can be made using the millivolt mode of a pH meter.
Major areas of usage include the treatment of industrial wastes, study of biological systems, oxidation of cyanide, bleaching of pulp, manufacture of bleach and reduction of chromate wastes. The measurement of ORP is also useful in pool water treatment as an indication of sanitation in relation to free chlorine parameter.
Waterproof Floating ORPTestr 10
APPLICATIONS
Chromate reduction, Cyanide oxidation, Swimming pool water, Pulp bleaching, Cooling towers, Aquaculture, Drinkingwater, Other redox applications.
LARGE DISPLAY SCREEN
Large dual-display LCD for enhanced readability. Important meter functions such as mode, battery level are clearly displayed for your convenience, at all times.
PUSH-BUTTON CALIBRATION
Calibration is quick and easy, with simple two-button operation. Push-button calibration adjusts readings by +/- 150 mV to match that of a known standard. Calibration standards are also available.
ACCURACY
Advanced microprocessor technology gives you up to +/- 2 mV accuracy across the entire range of -999 to 1000 mV.
LARGE PLATINUM BAND SENSOR
A large Platinum band on the sensor give you quick, stable, repeatable response and results. The larger surface area of the sensor minimizes contamination.
USER-REPLACEABLE DOUBLE JUNCTION SENSOR
Replace the sensor yourself! No tools or messy soldering is necessary. Sensors are equipped with a double-junction construction minimizing reference element poisoning. Spare sensors are supplied separately.
NON-VOLATILE MEMORY
Your calibration data is safe when you power-off or change the batteries. EEPROM retains all the vital information.
AUTO-POWER OFF
Meter automatically powers-off after 8.5 minutes of non-use to conserve battery lifeand save you money.
HOLD FUNCTION
HOLD measured values for later reading and recording, especially useful when you are in dimly lit and confined areas.
SELF-DIAGNOSTIC MESSAGES:
Battery power-level indicator, Or / Ur : Over or under-range, for ORP values, Er.0 : ORP calibration error
REINFORCED ENGINEERING PLASTIC
Your sensor casing is made of high strength engineering plastic for outstanding physical and chemical durability and lasting value.
