Advantages of the Hand-held measuring device XP201 humidity reference device
We from Lufft created with the XP Series true X-perts for a range of various measurements. The four device types are specialists on different measuring ranges. Our hand-held devices can be used for daily usage in service, in air conditioning and environment technology, in the food industry or for industrial temperature calibration.
XP201 - the most precise hand-held measuring device (0.8 %) for relative humidity:
With the XP201 we developed the most precise hand-held measuring device (0,5 %) for humidity, which Lufft ever offered. It can be used as a high-precision reference measuring instrument, e.g. in climate chambers and humidity generators, and is especially made for the industrial use. It distinguishes itself by its excellent stability, very good repeatable measurements, absolute hysteresis latitude as well as the non-existent drift of measurement values even at very high humidity levels. The XP201 has a mini USB port and comes with software for online data collection. It's delivered in a high-quality wooden case.
A few advantages in detail:
- High quality case
- Highest humidity precision (0.8%)
- DAkks calibration certificate included in delivery
- Resistive-electrolytic sensor, 2m cable and batteries included in delivery
- Easy to handle and robust sensor connection
- With automatic recognition
- Saves measuring campaignes
- Allows all climate data to be calculated and archieved
- Evaluation software SmartGraph3 included

XP201 - The X-pert of humidity measurement
The XP201 is the perfect choice for humidity reference in climate chambers or humidity generators. With the high-precision measurement of up to 0,5% for humidity it is suitable as reference measurement standard for industrial humidity calibrations. For traceability to national standards a DAkkS calibration certificate is attached in every delivery.
