Temperature/Pressure Dataloggers

Easy-to-use dataloggers record Humidity and
Temperature, and RHT35 model also records
Barometric Pressure. They use a standard USB

Download data to a PC

USB cover used as a stand

connection to transfer up to 48,000 readings to a
PC with data/time stamp in PDF or spreadsheet
format. Additional features include an 8-location
logger bookmark, 6-language options, programmable sampling interval, adjustable
alarm, and password-protected security log-in. Large LCD optimizes viewing
and the smart LED provides color-coded humidity, temperature, and barometric
pressure reading status.
