Hach Lange H-Series Meters and Non-glass Probes

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.


Portable - H160, H160G, H170 and H170G.

Benchtop - H260G, H260GB, H270G, H270GB, H280G and H280GB.
