Laboratory
two channel multi meter for pH, ORP,ISE, Conductivity, TDS,
Resistivity, Salinity and LDO. Instrument with electrode holder, without
electrodes.
- Have confidence in your readings!
- Optimised handling
- User friendly
- Fully GLP compliant communication and documentation
- Reliable O2 results with minimum effort
The digital meter/electrode system HQD combines reliability, flexibility and ease of use. Interchangeable INTELLICAL electrodes are recognised automatically and store all relevant data.
