A NEW range of temperature meters is available from Milwaukee Meters . The new SM801 and SM802 meters are three meters in one. They allow users to measure pH, EC (conductivity) and TDS with just one instrument and one single probe.
The SM801, with a conductivity range that goes up to 1990?S/cm, and a TDS range that goes up to 1990ppm, is an ideal tool for drinking water measurements.
The SM802, with a conductivity range that goes up to 6.00mS/cm, and a TDS range that goes up to 4000ppm, is ideal for testing in crop production.
Soil and well water that is too acidic or alkaline can have an adverse effect on plant nutrient and water uptake and directly affect the efficiency of fertiliser, herbicides, and pesticides.
Soil conductivity is checked before fertiliser application to pinpoint field needs and after fertilisation to establish its effectiveness.
The range of Milwaukee professional meters is supplied with the MA850 interchangeable probe to measure pH, conductivity, and TDS. The pH electrode utilises a fibre junction to reduce contamination when measuring fertiliser solutions.
Both of these professional meters calibrate manually in pH, conductivity and TDS.
