2.1.2 Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or
damage to
the instrument could occur if not observed.
2.2 Overview
The Waterproof Handheld meters are available in 2 models:
• Waterproof handheld H160 and H170
• The meter automatically identifies which type of electrode is attached when the
meter is turned on
The H160 and H170 meters accept both traditional style glass pH with BNC
connectors and non-glass pH probes with ISFET (Ion Sensitive Field Effect
Transistor) silicon chip sensors. The meters are designed to use only one pH
electrode (either a BNC pH electrode or an ISFET pH probe) at a time.
The H170 multi-parameter meter accepts conductivity probes with different cell
constants. The constant is automatically detected by the meter.
Both pH and conductivity probes can be attached simultaneously to the H170
model meters.
This is the safety alert symbol. Obey all safety messages that follow this symbol
to avoid potential injury. If on the instrument, refer to the instruction manual for
operation or safety information.
This symbol indicates that a risk of electrical shock and/or electrocution exists.
Electrical equipment marked with this symbol may not be disposed of in European
public disposal systems after 12 August of 2005. In conformity with European
local and national regulations (EU Directive 2002/96/EC), European electrical
equipment users must now return old or end-of life equipment to the Producer for
