1. Introduction
Thank you for selecting the Oakton
®
WD-35612-series thermohygrometer kit.
This kit includes a portable, microprocessor-based relative humidity and tempera-
ture hygrometer that measures relative humidity (RH) from 0 to 99.9% RH and
temperature from 0.0° to 199.9°F (–18° to 93°C). Model WD-35612-10 also reads
dewpoint. Use these meters for ambient air and environmental applications.
Caution:
Do not submerge the probe in a liquid or powder or else damage to the
probe may occur. Probe is for ambient air use only.
