ES pH Meters

pH METER, HAND HELD, WATER RESISTANT
This easy-to-use splashproof, portable meter delivers fast, accurate pH, ORP and
temperature measurements.
Robust splashproof casing Clear LCD display with low battery indicator. Keyboard
sealed against water & dirt HOLD function freezes readings for ease of recording
Calibration, temperature compensation and buffer recognition are all automatic
Three standard buffer values Calibration tags on LCD Auto shut-off.
Once the instrument has been calibrated, the buffer values used during calibration
are displayed with tags on the display screen. This keeps users informed of the
current calibration and helps to avoid taking measurements that are out of range.
Exchange the pH probe for an ORP probe to obtain ORP readings in the mV range.
Supplied with C51-5048 pH electrode C51-5974 temperature probe, pH 4.01 and
pH7.01 buffer solution sachets, 2 x electrode cleaning solution sachets, battery,
protective case and instructions.
Requires accessory ORP probe C51-5060 to obtain Redox/ORP readings in the mV
range.
