Termohigrometr LB-520
Hytherograph LB-520 is a small pocket device for measuring and recording the temperature and relative humidity of the air. The thermometer is powered by a lithium battery providing a long operating time of several years. The large LCD display alternately shows the results of both measurements.
The LB-520 thermohygrometer records over 16 thousand records of temperature and humidity measurements in programmed time intervals. Programming the registration time interval, and then reading the saved data, is carried out using a computer with the Logger program and a specialized reader attached to the USB port.
A simplified version of the hytherograph is the LB-520T thermometer used to measure and record only the temperature.
Basic technical data for the hytherograph LB-520:
Temperature measurement range:
- -30 .. + 80 ° C with internal temperature sensor, for LB-520 or LB-520
- -100 .. + 200 ° C external temperature sensor, for LB-520
- -200 .. + 550 ° C with external temperature sensor, for LB-520TE
Uncertainty of temperature measurement: +/- 0.1 ° C +/- 1 last digit, in the range of 0 .. + 50 ° C
Range of relative humidity measurement: 10..95%
Uncertainty of relative humidity measurement: +/- 2.0% in the range of 10 … 90%, +/- 1 last digit
More detailed data is described on the manufacturer’s website.
