Hygro-Thermometer Humidity Alert w/Dew Point
NIST Calibrateable and Programmable Alarms
Warning of High or Low Humidity Conditions
Features:
• Large, easy-to-read triple LCD displays % Relative Humidity,
Temperature and Dew Point
• %RH audible and visual alarms, with adjustable set points,
alert when humidity exceeds set limit
• Probe clips onto meter or extends on 18" (457mm) cable
• Max/Min with Reset function
• Rear calibration adjustment pot for Humidity and Temperature
(available with NIST certification and optional Calibration
Standards)
• Complete with built-in stand, wall mount bracket, remote
sensor and 2 AAA batteries; Optional calibration salt bottles
Model RH300-CAL
Applications:
• In summertime, identifies and
warns when conditions for mold
growth exist
• In wintertime, identifies and warns
when low humidity conditions for
static electricity exist
• Remote probe allows for
measurements behind walls
or in difficult to access locations
• Air temperature and dew point
temperature indicate where
condensation may occur
• Monitor conditions in laboratories,
storage areas and other controlled
environment settings
• Ideal solution when traceable ISO
calibrations are required by
operating standards
