DO Starter Benchtop Meter
HI2640 and HI2641 enable fast, accurate measurements utilizing the Hanna Instruments® HI764080 digital dissolved oxygen probe with an integral temperature sensor. The probe has a unique serial number and, once connected, is automatically identified by the meter.
Both meters measure dissolved oxygen in ppm and % saturation while the HI2641 adds data logging capabilities. The intuitive design simplifies configuration, calibration, measurement, data logging and transfer (to a USB thumb drive or computer). HI2640 and HI2641 benchtop meters offer a Basic Mode that streamlines measurement configuration and is useful for routine applications.
Additionally, HI2641 can be used in Standard Operating Mode, where all features and capabilities are enabled.
- Automatic parameter recognition
- Choice of measurement unit:
- ppm (mg/L)
- % saturation
- Simplified operation for routine measurements

- Auto sensor recognition
- Reduced errors and shorter learning time
Accurate, reliable results with HANNA Digital Smart Probe
The meters measure dissolved oxygen through its unique digital electrode. The HI2640 and HI2641 include the HI764080 digital polarographic dissolved oxygen probe with integral temperature sensor. This digital electrode is auto-recognized, providing sensor type, calibration data, and a serial number when connected by an easy to plug-in 3.5 mm connector.
- Direct signal processing for noise-free measurements
- Automatic sensor recognition
- Store calibration specific data from the last calibration
- Built with materials suitable for use in chemical analysis
- Integral temperature sensor
- 3 mm jack termination
- Connectors are sealed against moisture and corrosion and are more reliable than traditional BNC connectors.
- Unique serial ID for probe traceability
