QUESTIONS & ANSWERSAsk a Question
I cannot see the readings from the THGR221 sensor on my console
If you are replacing a sensor, please ensure that the old faulty sensor has had the batteries removed to avoid interference.
Oregon consoles need to be forced to ‘search’ for the new sensor. Please consult your manual to complete this process. Or contact us with the model number from the rear of the console if you no longer have this for additional help.
Will this replace my temp/humidity sensor for my WMR88/WMR88A Oregon Scientific
Yes it will. Please remember to force you console to search for the new sensor.
Is the THGR221 suitable for outside use? - is it all weather?
All Oregon sensors are classed as splash proof as they have ventilation holes for readings. The sensors should be placed out of direct rain, but are suitable to outdoor use. If the sensor gets too wet, the humidity reading may show as HH% and temperature unusually high.
Will this unit work with my BAR629HGU, please ?
No. only the THGR122NX sensor is listed as suitable which we have in exceptionally limited supply.
Is this a suitable sensor for Oregon wmr89 to replace defunct model THGN800?
Yes, this is listed and has been tested with the WMR89 station console.
