The new PHCN-85 is the latest
edition to the pH/ORP meters
from OMEGA. This transmitter and
controller offers a large TFT color
display and 32-bit processor/ARM
core operation system.
The PHCN-85 has two 4 to 20 mA
outputs to control or retransmit
the pH or ORP and temperature
value. In addition, this powerful
instrument has 3 relay outputs for
pH, ORP, temperature or timing.
The PHCN-85 is also packed
with standard features like RS485
communications, a calendar
function and password protection.
The power supply input even has
automatic polarity detection.
