Title: Worthless hygrometer
Review: This item is supposed to measure relative humidity and temperature. The unit I received does neither accurately. The hygrometer readings are way off, and my attempts at calibration did not correct this. The temperature readings are somewhat closer to being accurate, but are off by 2-3 degrees. And there appears to be no way to calibrate temperature. I bought this thinking it would be accurate because it is German-made. Considering the price of this instrument, I would strongly recommend against buying it.
