PHE-6510, electrode, $139, 
with PHEH-65-10, mounting 
assembly and cable, $59 
(both sold separately), 
shown smaller than actual size.
⻬ Large Backlit LCD Display 
⻬ Built-In Rechargeable Battery 
(Charger Included)
⻬ Simple One-Point Calibration
The PHH-128 indicator combines 5 meters 
into one easy-to-use wall mounting 
continuous monitor, featuring a large, duallevel, backlit LCD display. This meter can 
display the EC/TDS/CF (conductivity factor) 
of your solution together with the choice of 
either pH (probe sold separately), or 
oxidation-reduction potential (ORP) 
(probe sold separately) and temperature. 
The precision pH monitor immediately 
detects changes in solution pH or ORP.  
The multi-parameter water quality monitor is 
a versatile instrument with a reliable 
multi-probe system which is easy to read, 
economical and can be used by technical or 
non-technical personnel.
