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 (HI2620 and HI2621) measure pH and ORP with the supplied HI11310 Digital Smart pH Electrode.
Advantages of the pH Digital Electrode
- 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.
- The built-in temperature sensor ensures optimal temperature compensation. There is 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 automatic sensor recognition and a unique serial ID number for each Digital Electrode.
- Be proactive and know the health of your pH electrode with Sensor Check™. Predictive maintenance alerts notify you when to clean, recalibrate, or replace your pH electrode before it fails.
- Equipped with a modern 3.5 mm connector that is sealed to protect against moisture and corrosion.
