thermal shock chambers. Temp/Relative Humidity using either wet bulb/ Dry Bulb or electronic
sensors. The Model 620A internally contains the tables for WB/DB conversion, and Temp
compensation for the Vaisala HMM30 RH sensor to providing direct % RH setpoint entry and
process display values. Temp/Altitude. The Model 620A provides the conversion of altitude in feet
from the popular Omegadyne PX41 series pressure sensors for 1-15 and 0-20PSIA.
