HQ30d Portable Meter Kit
with LDO101 Optical Dissolved Oxygen Probe


Category: Tag:

Designed for water quality experts, the Hach HQ30d portable meter is an advanced meter that takes the guesswork out of measurements. HQd meters connect with smart probes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The durable portable meter and optional rugged probes are designed to withstand years of rugged portable and field use. HQd meters feature a simple user interface that does not require manuals or training to operate. The pH electrode included is a low maintenance, gel-filled electrode suitable for general purpose pH measurement.

  • Portable meter measures critical water quality parameters – without the need for multiple instruments
  • Intuitive user interface for simple operation and accurate results
  • Trust your measurements – IntelliCAL™ smart probes store all calibrations in the probe
  • Designed for demanding conditions
  • Convenient kit includes everything you need to start testing
