Optional probes
• HMP41 probe for measuring humidity and temperature in various
applications, for example in spot checks.
• HMP42 probe head has a diameter of only 4 mm and is 23.5 cm long.
This probe structure is specially for measurements in very tight
places, e.g. in joint spaces between tiles or in air conditioning
channels as well as for measuring the equilibrium humidity of e.g.
timber
• HMP44L for measuring humidity in concrete and other structures .
• HMP45 probe for measurements in channels and other places that are
difficult to reach and therefore require a probe head with cable.
• HMP46 consists of a 32 cm long probe head of stainless steel; the
HMP46 is optimized for measurements in relatively high
temperatures (up to +100°C, temporarily even +180 °C), in dirty
processes and in general in applications that require a robust probe
structure.
