measuring equipment - temperature
Hand-held pH meter (> 666 221)
with temperature sensor (> 666 241)
Temperatures can also be measured using the
hand-held measuring instruments > 666 221,
> 666 222 and > 666 224 with the
corresponding sensors. In addition to the temperature,
it is also possible to measure other
quantities such as pH, conductivity and oxygen
content concurrently.
