1. Milwaukee USER MANUAL PORTABLE pH METER MODEL MW101 Smart pH Meter AY Milwaukee __ ON OFF Temperature D Compensation i 3 Calibration pH4 10 pH7 MW 101 pH Meter Smart g Meter WARRANTY This instrument is warranted from all defects in materials and manufacturing for a period of two years from the date of purchase The electrode is warranted for a period of six months If during this period the repair or replacement of parts is required where the damage is not due to negligence or erroneous operation by the user please return the parts to either distributor or our office and the repair will be effected free of charge Note We reserve the right to modify the design construction and appearance of our products without advance notice Milwaukee OPERATION The meter is supplied complete with a 9V battery Slide off the battery compartment cover on the back of the meter Install the battery into the battery clip connector while observing polarity e Always remove the electrode protective cap before taking any measurement If the electrode has been left dry soak the tip bottom 2 5 cm in rinse solution M10000B for a few minutes to reactivate it Connect the pH electrode phat to the BNC socket on j the top of the meter i e Turn the instrument on E by pressing the ON OFF LZ B key e2. Make sure that the meter has been calibrated before taking any measurements see Calibration Procedure Set the temperature knob to the value of testing solution measured EY with help of an accurate thermometer I Immerse the tip 2 5 cm of the pH electrode into the sample and stir a gently After completing measurements on switch the meter off and store oF the electrode with a few drops of storage solution MA9015 in the protective cap CALIBRATION PROCEDURE A Preparation Two calibration buffers are required 1 pH 7 01 MA9007 2 pH 4 01 MA9004 if you are measuring in acid range pH 0 pH 7 or pH 10 01 MA9010 if you are measuring in alkaline range pH 7 pH 14 Use two beakers for each pH buffer One beaker for rinsing the electrode the other for calibration Use a thermometer with 1 C accuracy to measure the temperature of calibration solution B Procedure e Remove the protective cap from the electrode Rinse the tip of the electrode with some pH 7 01 solution then Ma 007 immerse the pH electrode 7 into a pH 7 01 buffer solution e Take the temperature of the buffer solution with a thermometer and set the temperature knob to the measured temperature e g 15 C e Adjust the OFFSET trimmer pH 7 on the front panel with J a small screwdriver until the yA LCD shows the pH value at va temperature of the buffer see the pH versus temperature c
