Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : iSpring BulletPoint1 : Used to test the ppm level of hard water BulletPoint2 : Automatic shut-off function helps save energy BulletPoint3 : Hold button retains measurement value for convenient reading BulletPoint4 : Comprehensive: great tool for testing hard water contaminated with arsenic, lead, aluminum and other metals BulletPoint5 : Hold button: holds measurement value when meter is removed from water for convenient reading and recording BulletPoint6 : Water resistant BulletPoint7 : Simultaneous temperature display BulletPoint8 : Sleek, lightweight design Color : Black DiagnosticTestSampleType : urine Directions : Under normal circumstances, the solution of the tasting paper will produce color changes a few second after contact with the test paper, remove the small test strip, compare the test results with the standard color on the card board, the smaller the number, the stronger the acidity, and the larger the value, the stronger the alkalinity. Please do not dip the ph strips in the test liquid. It might lead to incorrectly showing test result. Please drop the test liquid on the PH strips. It will perfectly indicates the real acidic or alkalinity substance.
