Vaisala HM42 - Application Examples

40
Application Examples
HM41
HM41 uses a fixed HMP113 probe, providing a compact
solution that is ideal for spot checks in open spaces.
The optional membrane filter for the HMP113 probe
increases protection against contaminants.
When measuring with
HM41, always hold the
meter at a sufficient
distance to avoid
affecting the results
with moisture from
your breath.
HM45
HM45 uses the same HMP113 probe as HM41. In HM45,
the probe is attached to a handle that is connected to
the HM40 indicator with a spiral cable, providing
additional reach.
