INTRODUCTION

The Sper Scientific 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.

under the route HTA01\. After
exiting the datalogger and
executing the function again, the
data is saved to the
HTA01001.XLS file until the data
reach 30,000 data columns. A
new file will then be generated
