Product overview
N O T I C E
Always disconnect power to the meter before an electrode is changed. Only use the meter as instructed in this
manual or instrument damage can occur.
The meter is available in two models:
• H160—pH and ORP
• H170—pH, ORP, conductivity, TDS and salinity
The H-series waterproof handheld meters use glass sensor electrodes with BNC connectors and
non-glass probes with ISFET (ion sensitive field effect transistor) silicon chip sensors. The meters
use one pH electrode (a BNC pH electrode or an ISFET pH probe) at a time. When a meter is set to
on, the meter automatically identifies the type of electrode that is attached.
