The Benchtop Meter for every lab setting

With a color LCD display, capacitive touch keypad, and clear on-screen text guides, users can easily set up, calibrate, and measure quickly. Our Simple Benchtop Meters are designed for both experienced professionals and those who prefer a straightforward, streamlined workflow.

Digital Smart Electrodes for enhanced measurements

Our Simple Benchtop Meters (HI2630 and HI2631) measure EC and TDS with the supplied Conductivity Digital Smart Electrode (HI763100).

Advantages of our Conductivity Digital Electrode include:

Designed for various industries and applications, this probe is durable and suitable for use in chemical analysis
Collect stable readings even in electrically noisy environments and eliminate drift with automatic noise filtering and digital processing
Built-in temperature sensor ensures optimal temperature compensation. There’s no need to manage an additional temperature probe
Change electrodes easily without recalibrating. All data from the last calibration is stored in the electrode for faster setup and less maintenance when switching electrodes
Gain traceability with auto sensor recognition and a unique serial ID number for each Digital Electrode
Equipped with a modern 3.5 mm connector that is sealed to protect against moisture and corrosion
