Pen Type Meter that can simultaneously measure & display pHresults
The electrode has been used(laid) for long time from the last calibration
The electrode has been used in particularly taxing conditions
The utmost accuracy is required
Measuring Range: 0.0 to 14.0 pH
Resolution: 0.1 pH
Accuracy: ¡À 0.1 pH
Batteries: 3 x 1.5V (AG-13 Button Battery)
NOTE: calibration powder is needed for re-calibration.( not included)
1. immerse the electrode in PH 6.86(under the temperature of 25¡æ)standard buffer solution of phosphate and gently shake the eletrode.
2. regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained.
3. immerse the electrode in PH4.01 or PH 9.18 the standard buffer solution of borax.
4. after about one minute, until the buffer solution value corresponding to the measurement temperature is obtained.
