The RH318 is a low cost, high
performance handheld meter with
data logging ability. It offers a large
dual back-lit display to show the
temperature and humidity from a
handheld probe and can display a
dew point measurement. The
temperature/humidity probe uses a
semiconductor and polymer
capacitive sensor and a thermistor
temperature sensor. Windows
based software and USB interface
cable is included to allow real time
or recorded data to be read by a
PC through the USB/RS232 port
(RS232 interface cable is optional).
Probe can extend up to 1.5 m (5')
with optional extension cable.
