Compact conductivity/°C measuring instrument - With range of probes

testo 240

testo 240 is a complete conductivity measuring instrument and a high standard thermometer combined in one compact, waterproof housing.

Measurement errors caused by high conductivities and deposits on the electrodes are avoided thanks to the 4 electrode engineering used. The salt level (NaCI) in an aqueous solution can be measured directly.

» Long life of measurement cell thanks to 4 electrode engineering

»Extremely wide measurement ranges with only one measurement cell
