Product Description

Details

Waterproof, accurate and portable, these handy little pocket meters are true go-anywhere’ pH testers with replaceable electrodes.

Main Benefits:

  • Dual level LCD display and rubberised keyboard.
  • Displays pH and temperature.
  • Replaceable electrodes to prolong life of the meter.
  • Automatic buffer recognition and calibration.

We recommend that the pH testers electrodes are stored in a pH4 solution and that testers are calibrated in a pH7 solution (see below).

Instructions

  • To calibrate, simply put the electrode (ensuring it is clean and dry) into a sachet of ph7 buffer and wait for about 30 seconds for reading to settle. Press and hold the mode button until the word "cal" appears on the screen. "7.01" will be displayed on the screen and after the display has settled, the word call will appear and you can take the meter out of the buffer.
  • You can re-seal the sachet by rolling the top over and using a "bulldog" clip. If you store this in a dry environment, away from sources of heat or cold, you can use this sachet of buffer a few more times. You may wish to recalibrate once a week or, if you use the ph meter less frequently, calibrate before each use to ensure accuracy.
  • After calibration, rinse the meter (without getting the red part wet) and shake to dry. The probe should be stored in buffer 4 solution when not in use. Always rinse the buffer 4 off before taking a reading.
