TPI 397 Pen Style PH Meter

.TPI 397 Pen Style PH Meter PH Meter Waterproof design protects the meter during use Low power consumption extends battery life for low operation costs Replaceable Glass Test Tip Electrode that screws on for ease a solid of use Applications: Boiler water testing for proper PH level to avoid internal material degradation Check automotive radiators to avoid acid level build up resulting from dissimilar metals On-site water testing for wells and septic systems; saving lad testing time Quickly and easily test aquariums, spas and swimming pools for proper PH levels Operating Instructions Remove the protective cap and press the ON/OFF button to turn on. (Calibrate the unit with known PH liquid for first time use, or using after long-term storage) Dip the electrode into sample solution. Stir gently and wait for a few seconds until the display value stabilizes. The readout is the PH value. After testing is completed dip the electrode into distilled or de-ionized water. Stir gently, then use a soft cloth to gently dry the water from the glass test tip. CAUTION: Use care when drying the tip to avoid damaging the test tip. When storing the PH meter - turn the unit off, put a few drops of distilled water or de-ionized water on the sponge inside the cap, put the cap on the PH meter. The sponge with liquid will keep the test tip clean and ready for the next use. It is now properly stored. If the unit cannot be turned on or the display fades, replace all of the batteries. Calibration The PH meter has 2 calibration points. Point 1 is inside the battery compartment at the top. Point 2 can be seen it when you remove the battery carrier, it's located below the battery. Clean the glass test tip electrode with distilled or de-ionized water. Dip the electrode into 6.86PH (or7.00PH) buffer solution. If the display does not show between 6.80 - 7.00 PH, adjust Point 1 to make it display 6.90PH. Clean the glass test tip electrode with distilled or de-ionized water.Wide PH range of 0.10-14.00PH covers most applications.Operating temperature from 40 -120°F (5 - 50°C); for temperature compensated readings.Waterproof design protects the meter during use.Low power consumption extends battery life for low operation costs.Auto-off function turns power off automatically after 10 minutes
