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 annula PTFE junction
 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 electri-
cal interferences.
Each meter comes with:
  HI 72911 pH/temperature probe
 3x1.5V AA alkaline batteries
