*1 Accuracy is the closeness of agreement between the measured value and actual value of the standard solution in the measurement of the same standard solution as the one used for calibration. Temperature during the calibration and measurement is the same. The error of standard solutions and rounding error (±1 digit) are not included.
*2 IP67: no failure when immersed in water at a depth of 1 meter for 30 minutes
Please note that the meter cannot be used underwater.
