The Protimeter Hygromaster has been the professionals number one choice for the investigation of humidity and concrete floor investigations. There are many applications where moisture and temperature trend analysis is required to gain a full understanding of a situation.

Surface temperature measurements can also be measured with an optional surface temperature sensor, making this instrument especially suitable for condensation risk assessment and diagnosis.


The Protimeter Hygromaster features a range of detachable sensors.

The Hygrostick measures humidity in the 30-100% rh range and may be used with Protimeter humidity sleeves that are used when measuring the equilibrium relative humidity of solid walls and floors.

The new Quickstick features a fast responding sensor with a range of 1-100% rh making it more suitable for general air quality applications, including outputs from dehumidifiers and HVAC systems.


The Protimeter Hygromaster has a data-logging mode to meet this requirement. The user sets the instrument to record measurements as required and leaves it in place for the required period of time. The memory contents are then downloaded to a PC using optional software where the logged measurements are displayed in tabular and graphical form.
