DBO Meter HQ40D

Portable multifunction BOD meter with two channels for pH / ORP / conductivity / TDS / resistivity / salinity / LDO / ISE

Portable BOD meter with two channels for pH, ORP, conductivity, TDS, resistivity, salinity, LDO, and ISE. This BOD meter features the following characteristics:

- Exceptional reliability and ease of handling

- Versatile electrodes for all applications

- Reliable results from inaccessible and long-distance measurement locations, including pH

- O2 results without errors, no calibration or electrolyte replacement

- Total data management according to GLP

- The digital electrode/measurement system combines reliability, flexibility, and ease of use

The interchangeable INTELLICAL electrodes are automatically recognized and store all relevant data. The robust outdoor versions, virtually indestructible, with various cable lengths, allow measurements even in previously inaccessible locations.
