Little Havana Hygrometer-Thermometer
Shaped like a 4½ x 50 Rothschild cigar, the Little Havana hygrometer can be placed in with your cigars or magnet mounted. Features include buttons for checking min/max temperature and humidity levels in Fahrenheit or Celsius. Accurate within +/- 1.8° Fahrenheit and +/- 1.5% RH. Battery included.
I own two of these that I purchased 5 years earlier. I recently added a new humidor and bought another one of these hygrometers. This new one is about 15 degrees higher than actual humidity. Temperature is also off by about same amount. I guess they're building them cheaper now. I wouldn't recommend this. Try another digital type. It's a shame because my older models still work fine and are very accurate.
