• HM Digital PH-80 Handheld Hydro Tester pH Meter:
• The PH-80 is a reliable pH meter that is ideal for testing applications such as hydroponics & gardening, pools & spas, aquariums & reef tanks, water ionizers, drinking water and more.
• The PH HydroTester Handheld Meter measures pH and Temperature.
• The HM Digital PH-80 has one-touch automatic digital calibration.
• This pH Meter is water resistant.
• The Handheld Hydro Tester PH-80 displays temperature simultaneously.
• This handheld ph Meter has a sleek and lightweight design.
• The PH80 has a large LCD display.
• This pH Meter has Automatic Temperature Compensation (ATC).
• Includes storage solution in a sponge embedded in a translucent cap.
• The Hydro Tester has an auto-off function, data-hold function and low-battery indicator for convenience.
• The PH-80 is factory calibrated to pH 7.0. The meter can easily and quickly be recalibrated to pH 4.0, 7.0 or 10.0 using the meter's simple one-touch process.
• This pH Meter includes a cap, batteries, storage solution and pH 7.0 buffer.

NOTE: Your PH-80 is shipped with the sponge in the cap dry. Prior to use, pour a small amount of storage solution from the Mylar packet into the sponge so that the sponge is moist (not dripping wet). Put the cap back on and allow to soak for 15 minutes (standing upright) prior to use. Additional electrode storage solution is available for purchase.

Care and Maintenance
• Do not drop or completely submerge the unit in water or dip beyond the maximum immersion level. This unit is not watertight and is not covered under the warranty if water gets into the unit.
• Do not store the unit in high temperature or direct sunlight. This will shorten the lifespan of the product.
• After repeated usage in high TDS water, it is advised to clean the electrodes to prevent residue build-up.
• When necessary, clean the electrodes by soaking the tip in an acid (e.g., vinegar or diluted hydrochloric acid (muriatic acid)) and then rinsing well in water. If it is heavily fouled with organic material, soaking the tip in alcohol or bleach may help. Gentle wiping with a soft, nonabrasive cloth may also be acceptable.
• For best results, always rinse the sensor pins in distilled water and allow to air dry before replacing the cap. TDS electrodes should be stored dry. (NOTE: pH and ORP electrodes must be stored in a special storage solution.).
• The batteries may need to be replaced after extended usage or lifespan. To change the batteries, remove the top compartment of the meter (on the opposite end of the sensor for handhelds, on the rear of the unit for monitors) and insert new batteries according to the polarity of the diagram inside.
