INTRODUCTION
This Sper Scientic Environmental Meter with SD Card
Datalogger (Model 850071) is an extremely fast and
accurate meter with multiple functions. The meter reads
humidity, air temperature, air velocity, and measures
light in Lux or Ft-cd. Optional Type K/J thermocouple
probes available.
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. Each data set includes the measured
value along with the time and date. Sampling time can be
set from 1 second to 3600 seconds. Alternatively, manual
datalogging is available to record 99 readings.
