The Protimeter BLD7750 Hygromaster 2 with Short Hygrostick can be used to measure surface temperature, air temperature and relative humidity. It is also capable of performing a number of psychometric calculations, making this thermo-hygrometer suitable for monitoring and testing air quality, as well as HVAC equipment and dehumidifiers. Please see the video below for an overview of this product.
In order to facilitate the Protimeter BLD7750 Hygromaster 2 Thermo-Hygrometer’s extensive measurement capabilities, it includes a variety of fast responding, high-accuracy sensors. These include an infrared, non-contact temperature sensor with a range of -20°C to 80°C.
In addition to this temperature sensor, the Protimeter BLD7750 Hygromaster 2 Thermo-Hygrometer is supplied with a short Hygrostick sensor, optimised for conducting high-range relative humidity measurements. It has a relative humidity range of 30 to 100% RH. This sensor extends the Protimeter BLD7750 Hygromaster 2 Thermo-Hygrometer’s scope-for-use to include measuring the equilibrium relative humidity of concrete floors.
Measurements can be viewed on the Protimeter BLD7750 Hygromaster 2 Thermo-Hygrometer’s colour display and may be saved to its extensive internal memory. This thermo-hygrometer has the capacity to store up to 8000 time-and date-stamped, manually saved measurements, as well as up to 6100 measurements recorded using the automatic logging function.
The memory and measurement functions present on this instrument can be easily accessed using the Protimeter BLD7750 Hygromaster 2 Thermo-Hygrometer’s simple-to-navigate interface.
Finally, in addition to the short Hygrostick, the Protimeter BLD7750 Hygromaster 2 Thermo-Hygrometer is supplied with a practical, protective carry case, ensuring that the instrument can be safely and easily transported between worksites.
The Protimeter BLD7750 Hygromaster 2 with Short Hygrostick and Case is a collection of products designed to allow the user to measure the surface and air temperature, as well as the relative humidity of a variety of instruments and materials in an array of environments.
