RTGR328NA Wireless Temperature and Humidity Sensor with Clock
temperature and humidity sensor with atomic clock works with the new Oregon Scientific
time and weather
stations that receive their time signals from an associated remote.
The Oregon Scientific RTGR328NA
Wireless Temperature and Humidity Sensor with Clock is a 5-channel
displaying remote that contains not only temperature and humidity sensors but also the atomic clock receiver for the
associated main weather station. The remote receives
time synchronization signals from the U.S. atomic clock in
Colorado (radio station WWVB, 60 kHz) and transmits this information, plus temperature and humidity
data, to the main station via 433 MHz radio waves. As a result, the main station's
clock maintains the same accuracy as the atomic clock in the
RTGR328NA. We're offering this remote in case you need a replacement for
the one that came with your Oregon Scientific time and weather station.

Styled in white,
the RTGR328NA has a gray bezel around its two-line LCD panel. The top line
of the display shows the time and a
time-signal reception icon. The bottom line shows the selected
channel number for the remote and automatically alternates between temperature
and humidity. With adequate power (from lithium batteries), the display
should operate down to about -20°F (-29°C). Lithium batteries provide superior performance in sub-zero
temperatures and actually retain their power down
At the time of this writing, the
weather stations with which the RTGR328NA
remote operates are the Oregon Scientific AWS888, BAR321HGA, and
BAR998HGA, all of which include one RTGR328NA as part of the weather
station package. Please be aware that the RTGR328NA
cannot function as an atomic clock receiver for any Oregon Scientific weather
station that does not originally come with this remote.
main (display) units for the above weather stations can operate with
multiple remotes, only one remote can be the type that receives time
synchronization radio signals,
and that's the RTGR328NA. The additional
remotes must be other compatible models that do not have atomic clock
receivers. When using multiple remotes, be sure to select a different
channel number for each.
The optional remotes
(without time signal reception capability) that can work along with the RTGR328NA are as follows:
- THGN123N (3-channel sensor). This is a
non-displaying temperature and humidity sensor.
- THGR228N (3-channel
- THGR268 (3-channel
sensor). This is a temperature and humidity sensor with its own
- THGR328N (5-channel
- THR228N (3-channel
- THR268 (3-channel
sensor). This is a temperature-only sensor with its own display.
- THC268 (3-channel
sensor). This is a temperature-only sensor with a probe on a 10-foot
(3-meter) wire and its own display.
The THGN123N, THGR268, THR268, and
THC268 are currently available. The other three remotes whose numbers end in N
are new units that, at the time of this writing, are not available
Maximum transmission range
of the RTGR328NA is 328 feet (100 meters) in open space with no
interference. If the main station has a shorter reception range than the
sensor's transmission range, you must move the sensor closer for
In the battery
compartment of the RTGR328NA are a Channel 1, 2, 3, 4, or 5 selection switch
and four control pushbuttons. One pushbutton selects °F or °C for the display,
another selects the continental U.S. time zone (P, M, C, or E), and a
third button initiates a search for the WWVB time synchronization radio signal.
The fourth button is a Reset button that you press
after inserting batteries.
has a fold-out stand for placement on a horizontal surface, or it can be
wall-mounted via a keyhole slot on the back. This remote is
water-resistant but not waterproof. Choose a mounting location where the
remote is protected from direct sunlight and direct precipitation.
Wireless Temperature & Humidity Sensor with Clock operates on two AA alkaline or lithium batteries. Two alkaline
batteries are included.
Average battery life is approximately 1 year. A low-battery icon appears
below the channel number in the second line of the display when
replacement becomes necessary.

We can handle large orders
for nearly anything we have by special order, and quantity
discounts are available.
For quantities of 10 or more, or if you want more than we have in stock, please
email us at email@example.com,

the phone as it takes time to investigate each situation.
If there is no order button, most likely there are
availability problems. We expect to be out of stock for more than a few days.
If the shopping cart page indicates that there are no units available, then we are temporarily out of stock. The item should be available in a day or two. To avoid disappointment, our
inventory control system prevents us from taking an order for something we don't have on the shelf.
