In the second half of 2019, the miniature air parameter meter LB-531 was introduced for sale. It is a simpler version of the LB-532 recorder, deprived of the ability to record measurements in the internal memory, although it has the ability to remember extreme values: minimum and maximum. The device measures the temperature and relative humidity of the air. Optionally, you can order versions that also measure pressure as well as the intensity of light radiation.
The device powered by a lithium battery can work up to 5 years. The LB-531 thermohygrometer is sold with the calibration certificate from an accredited calibration laboratory at the customer’s request. The device can be equipped with a magnetic holder or stand.
