Specialized Sensors
Accurate measurements of challenging
samples such as organic solvents, solid
and semisolid food or highly viscous
liquids: benefit from Intelligent Sensor
Management (ISM
®
) to ensure the right
sensor is used for each sample.
Tough Enough
Protection from splash water, chemicals
and dust to prevent inaccurate results and
corroded connectors: the IP54 rating of

surement with the analysis it originates
from: SevenDirect™ simplifies data entry
and records additional information like
date and time, user ID and sensor ID.
