7.7 Measuring range, operating range, accuracy and supply; datalogger type ...H2
Temperature measurement
(Logger with sensor typical;
logger at room temperature) -50.0°C.. -25.0°C
For a total sensor cable length > 5m the accuracy ranges have to be expanded by 0.3°C and the
total cable length for both sensors together may not be longer than 20m!
Measuring the relative air humidity
Sensor
For a total sensor cable length > 5m the accuracy ranges have to be expanded by 1%rH and the
total cable length for both sensors together may not be longer than 20m!

See the diagram for the range of applications of the rH/T
universal probe 3087-NB with extended temperature range.
Can be used for short times at temperatures up to 110°C
and permanently at temperatures up to 100°C.
Warning
The temperature range for sensor cable 3218-Sxx is only -
35°C.. 80°C.
The cable should not be moved when subjected to high
temperatures!
