Designed to Last
Hach's H-Series meters feature dual-technology
capabilities for taking readings from ISFET (Ion-Sensitive
Field Effect Transistor) and glass pH probes. ISFET stainless
steel probes in this electrochemistry line contain a virtually
unbreakable sensor that provides superior performance to
traditional delicate glass electrodes. Engineered to withstand
harsh use in the most difficult applications, the H-Series
meters and probes give years of reliable service.
ISFET Technology
ISFET sensor
technology contains
several proprietary
layers deposited
selectively on a
silicon chip
substrate. The final
layer possesses an
affinity for hydrogen
ions only. The
quantity of
hydrogen ions at
or near the sensor
surface causes an
electrical effect that
is detected and measured as pH.
Easy Storage and Maintenance
Unlike conventional electrodes, ISFET-style sensors store
dry, eliminating the need for storage solutions. To clean
the sensor, simply use a toothbrush and detergent.
Compare this to traditional glass electrodes with
hard-to-reach crevices for difficult cleaning and an
additional sample preparation step. After use, just
replace the protective sensor cap.
Operates in Restrictive and Challenging
Environments
With both benchtop and portable options, the H-Series
addresses lab and field needs. All meters compensate for
temperature automatically in pH readings. Non-glass pH
probes offer convenience and ruggedness, excelling in
applications such as food and beverage, academic teaching
labs, environmental studies, agriculture, and petrochemical.
Probe options include standard, micro and piercing versions
to allow easy insertion and cleaning.

Portable Meters
Rugged portable meter systems provide a large LCD
display with LED backlight and measurement of pH (ISFET
or glass), mV, temperature, conductivity, Total Dissolved
Solids (TDS), salinity and Oxidation Reduction Potential
(ORP). They also offer a waterproof enclosure with an IP67
rating. G-version models include the added features of
Bluetooth wireless remote control and data transfer,
GLP-related features such as date and time stamping,
calibration recall, password-protected set up, ISE capability
and additional data point storage.
Benchtop Meters
Laboratory benchtop models feature AC and/or battery
operation, ergonomic design and measurement of pH
(ISFET or glass), mV, temperature, Oxidation Reduction
Potential (ORP), Ion-Selective Electrode (ISE), conductivity,
TDS, salinity and dissolved oxygen. All benchtops include
GLP-related features, a reference electrode input, an IP42
rating, with optional Bluetooth models also available.
Models
Portable - H160, H160G, H170 and H170G.
Benchtop - H260G, H260GB, H270G, H270GB, H280G and H280GB.
