Check out Oregon Scientifics' Sensor Compatibility Chart 

WIRELESS TEMPERATURE & HUMIDITY SENSOR

This additional 433MHz remote sensor is for use with Oregon Scientific's CABLE-FREE THERMO-HYGROMETERS with 3-channel main unit. The sensor features a splash-proof case design, LCD displaying temperature and humidity, LED transmission indicator, user-select temperature display (Celsius or Farinheight), temperature measuring range -30ºC (-22ºF) to 60ºC (140ºF), humidity range 5-95%, table or wall-mount and low-battery indicator.  Uses two UM-3 or AAA size 1.5-volt alkaline batteries. Suggest Lithium AAA for very cold conditions

WIRELESS TEMPERATURE SENSOR

THR sensors feature an LCD screen on the sensor unit for viewing temperature at the remote location as well as the base unit.

WIRELESS SIGNAL REPEATER

Extend the possibilities

If the 300 feet transmission operating range of the wireless weather stations is not enough for your application or location, the signal extender is the solution. It increases the transmission operation range between you weather station and the remote sensors an additional 300 feet!

Works with THGR268, THR238, THR138, and THN138 ONLY!
