My outdoor thermometer isn’t accurate - Measuring Tools & Sensors

Two possibilities, one with boiling hot water the other with some ice cubes in a cup.

immerse the thermometer in a jar of boiling water and adjust the themeometer to read 100C or 212F hold it down witha piece of adehasive tape firmly and glue it.

Or imerse it a jar of ice with water so that the ice begins to melt and adjust the themometer murcury line to line up with 0C or 32F firmly with tape and glue it in place.

You are done

My outdoor thermometer transmitter was sending hhh instead of the current temperature. I opened it up a bit and sprayed it with compressed air (Ultra Duster or similar product) to clean the temperature sensor. It has worked fine since then.

Thanks for the great question. While I am a avid smoker and outdoors men I can tell you that most of these gauges are not real accurate and only measure ambient air temp. Also the placement of the gauges in the upper portion of the smokers will give a higher reading because heat rises. My best suggestion is that you use a stand alone meat thermometer for guaranteed great smoked meats. You can also measure the temp inside the smoker using a stand alone thermometer and read your guage at the same time. Than you can use adjust the door thermometer by turning the center of the probe on the back with a pair of plier. You should see a nut head or a locking nut that allows you to hold while you turn the face of the thermometer to recalculate it. Some of these may not be adjustable and you can purchase a adjustable replacement online.
I hope this has given you a better perscpective on these gauges and will help solve you problem.

how much is it off? What are you comparing it to?

Meat thermometers are accurate to within plus or minus 1-2 degrees F.

Hello dear

Thermometer reading is more accurate then dinamap reading.
In dinamap take three reading and then the average of these three are the correct one, But in thermometer the first reading is accurate.
Well in dinamap it shows usually plus minus 5 difference.

Hope the answer will help, do rate it please

Regards

Take the batteries out of both units (the base and the outdoor thermometer). Put the batteries back into the outdoor unit, and then put the batteries back into the base unit. This worked for me.

INSTALLING BATTERIES
IMPORTANT:Read the section SETTING UP THE THERMOMETER before installing the batteries for the first time.

1.Remove the rear cover of thermometer. Install 2 new AA batteries. Replace battery cover.
2.Loosen 4 screws on rear battery cover of the Remote Sensor and slide battery cover off.
3.Install 2 new AA batteries .
4.After batteries are installed, the remote sensor will begin transmitting and automatically register to the Thermometer
(within range) after several minutes. However, you can also press the small button in the battery compartment (labeled Tx) to register the Remote Sensor to the Thermometer immediately
5.Replace battery cover and tighten 4 battery screws. Make ure that the battery cover is fully on and tightened to assure a watertight seal.

SETTING UP THE THERMOMETER
The thermometer can monitor up to two different Remote Sensors on two separate channels. Add-on remote sensors can be purchased separately and are compatible with the GE Wireless Thermometer/Clock (model GE5805WS4) as well as this unit. When first installing, always insert batteries into the Thermometer first, then into the Remote Sensor.
The thermometer uses random security code technology-it will learn the random code of the first Remote Sensor it detects and log in as channel 1. Channel 2 will register in the same way. NOTE: Registered channels will be erased when the batteries of the Thermometer or Remote Sensor are removed. When replacing batteries for a Remote Sensor, remember to clear the corresponding channel of the Thermometer in this way:

1.Remove batteries from the remote sensor (step 2 of installing batterie)
2.Select the channel that you would like to clear by pressing the CH button on the Thermometer until this channel number is displayed.
3.Hold the CH button for 3 seconds to clear the channel
4.Follow steps 3-5

MOUNTING THE REMOTE SENSOR AND THERMOMETER
Remote Sensor is suitable for outdoor mounting (watertight) at a range up to 100 feet from the Thermometer. HOWEVER, HE UNIT SHOULD NOT BE MOUNTED IN A POSITiON WHERE IT WILL BE SUBMERSED IN WATER, OR EXPOSED TO DIRECT SUNLIGHT, OR NEAR OTHER SOURCES OF HEAT OR COLD (I won't bother typing the rest) except for:

LOW Battery icon for the sensor will show up on either the
ch 1 or ch 2 display depending on which sensor is losing battery power.

Battery life 6 months
Temp Range Therm 32 to 122 deg F
Remote Sensor -58 to 158 deg F *
*Alkaline batteries can freeze temporarily at temps below -4 deg F. In this condition, the Remote Sensor cannot accurately transmit temp info to the Thermometer. This limits the effective minimum temp fo the Remote Sensor to -4 deg F

Operational Range....>50ft(and up to 100ft)(less interferances)

RF Channel ....refresh to "---" if no signal received in 60 minutes
