INTRODUCTION
The Sper Scientic RH/Temperature SD Card Datalogger
(Model 800021) is an extremely accurate meter with fast
response times that reads relative humidity (RH), ambient
temperature, dew point, wet bulb, and functions as a Type
K/J thermocouple thermometer.
This meter features a real time SD memory card
datalogger. Standard, portable SD memory cards provide
unlimited data storage and upload pre-formatted data
directly to Excel, eliminating the need for cables or
software. Alternatively, manually record 99 readings for
on-screen review or stream data directly to a computer
using the optional software and cables. Each data set
includes temperature, RH, time and date.
