ORP Meter RISEPRO Pen Type Redox Tester -1999mV to 1999mV Millivolts Backlight Pool Spa ORP Water Quality Portable Lab Use

ORP Meter RISEPRO Pen Type Redox Tester -1999mV to 1999mV Millivolts Backlight Pool Spa ORP Water Quality Portable Lab Use

• PRE-CALIBRATED AT FACTORY - This ORP meter has been pre-calibrated at factory at 265MV for immediate use. You may calibrate with other value's buffer solution if considered necessary for measuring at other ranges. NO CALIBRATION SOLUTION IS INCLUDED!
• SIMPLE N' FAST - RISEPRO® ORP meter can measure the ORP (Oxidation Reduction Potential or Redox) of your solution or system in a simple and fast way.
• ESSENCE OF REGULAR CHECKING - The more positive the ORP value, the greater the power of water disinfection, thus the faster the microorganism is killed (oxidized). It is important to measure the ORP level regularly to ensure a healthy ORP level is maintained.
• MEASURE RANGE & ACCURACY - The measure range is -1999 mV to 1999 mV with 1mV resolution and accuracy of +/- 5mV.
• WIDE APPLICTIONS - Great tool for water quality control, aquarium, hydroponics, spas, swimming pools and other water systems.

<b>Important Notice:</b><br> <br> This ORP meter has been pre-calibrated accurately in advance for your immediate use. It is recommended to calibrate at 265MV buffer solution but can also be calibrated by other buffer solution with different ORP value. NO CALIBRATION SOLUTION IS INCLUDED!<br><br> This RISEPRO® ORP meter can measure the amount of Oxidation Reduction Potential (<b>ORP or REDOX</b>) level in sample quickly and conveniently. ORP is a tendency of the solution to either gain or lose electrons. The <b>backlight LCD</b> equipped enables users to do testing and measurement even in dark fields.<br> <br> ORP is correlated with the quality and purity of water. ORP meter has a wide range of applications in water sources, aquarium, hydroponics, spas, swimming pools and other water systems.<br> <br> <b>Specifications</b><br> <br> <li>Measuring range : -1999 mV to 1999 mV</li><br> <li>Accuracy : ±5 mV</li><br> <li>Resolution : 1 mV</li><br> <li>LCD Display : 4 Digits with backlight</li><br> <li>Operating Temperature : 0 - 50°C (32 -122°F)</li><br> <li>Calibration : By mini screwdriver (included)</li><br> <li>NO CALIBRATION SOLUTION IS INCLUDED </li><br><li>Power Supply : 4 × 1.5 V (AG-13) Button Cell Battery (installed)</li><br> <li>Dimensions : approx. 151mm × 33mm × 20mm (5.94' x 1.30' x 0.79' inch)</li><br> <li>Item Weight : approx. 53g</li><br> <br> <b>One set included</b><br> <li>1 x ORP Meter</li><br> <li>1 x Mini Screwdriver</li><br> <li>4 x AG13 button cell batteries (installed)</li><br><li>1 x Instruction Manual</li><br>1 x Sturdy Storage Case</li><br>
