Is this meter nitric acid compatible? What are the wetted materials used?

Asked by: Nitricity1
Thank you for your inquiry about the meter. The wetted material is an epoxy which is not chemically compatible with Nitric acid. A suggested pH probe is the PHE-5580 series which is a stainless steel body that is good up to 50% concentration.

What is the different between Salt mode and TDS mode?

Asked by: dd123
Thank you for your inquiry about the portable meter. Salt mode is measuring the percentage of salinity in samples and TDS is Total Dissolved Solids and represents the total concentration of dissolved substances in water. TDS is made up of inorganic salts, as well as a small amount of organic matter.
