HI 99141 is a portable, microprocessor-
based pH and temperature meter with a
special probe.
HI 72911 is a rugged double junction pH
electrode with a flat tip and stainless-steel
body that also functions as a matching pin.
The electrode has an annular Teflon
® junc-
tion for maximum surface contact and the
flat tip is easy to clean and prevents solids
in solution from collecting on the sensor.
Moreover, a built-in temperature sensor al-
lows simultaneous pH and temperature
readings and a mini amplifier renders mea-
surements impervious to noise and elec-
trical interferences.
Each meter is supplied complete with:
• HI 72911 pH/temperature probe
• calibration & cleaning solution sachets
• 3x1.5V AA alkaline batteries
• instruction manual
• rugged carrying case
