: pH : 2 Wired DC powered pH Monitor / Controller (Alpha
PH500)
Our competitively priced Alpha pH500 Process Control pH meter
is DC powered (12 to 24 VDC) and can be installed in serial loop
making it ideal for use
in power plants or any commercial sites where electrical interference
can make pH readings erratic. The Alpha 500 shares many of the advanced features of the Alpha 2000 and 1000 units,
such as Scaleable
4-20 mA
Output for better resolved output at chart recorder and other
peripheral devices Galvanically Isolated 4-20 mA Output also Two Level Password
Protection preventing un authorized tampering with settings.
