SuperUltralight Temperature Indicators for Outdoor and Body Temperature/Fever Indication
- This topic is empty.

Check the weather and check if you have a fever!
These are probably the lightest temperature indicators on the planet. Less than 0.09oz for all 4 indicators! The package includes 3 outdoor temperature indicators and a reusable personal body temp/fever indicator (hold it against your forehead for 2 mins to check your temperature). All 4 pieces together weight in at a mere 2.4450g! I also offer a vinyl storage case to contain them all that weighs 5.3741g.
The advantages of these indicators are:
– Don't need batteries
– Are flexible and nearly indestructible
– Super ultralight-weight (virtually nonexistent weight!)
– Compact
– Take only the indicators you will need (depending on the season)
– Vinyl case doubles as a side-by-side holder for all three outdoor temp indicators
– Easily mounts to trekking poles or any other surface
– Temp readings with a simple glance while hiking or in your trekking pole supported tarp or tarptent
– InexpensiveThe only fault of these temperature indicators is that they should be kept indoors and out of light when not in use to prevent degradation of the liquid crystal used in them. Extremes in temperature, humidity and sun exposure does degrade the liquid crystal and tends to lower their reaction points (aka – make them read temps as being higher). I usually replace mine every year and use the old ones for less vital temp monitoring (i.e. – Tape it to your workbench in the garage or somewhere in the basement, etc.) If mounting them to trekking poles, I'd recommend replacing them after a months time of sun and element exposure, as they will receive more sun and element exposure than if kept in your pack or tent/shelter out of the sun.

Additional Lower Temp 7-Level Strip:

Shouldn't need to mount these to anything specific to get an accurate reading as there is no real substantial material around the liquid crystal to act as a buffer. The vinyl case doubles as a side-by-side holder for all 3 outdoor indicators and allows you to take a temp reading without touching the indicator and possibly altering the reading.
Additionally, with their adhesive backing…these can easily be mounted to a trekking pole for temps in a glance. Works great if you have a tarp or tarptent in which you use your poles to support it and they are visible while in the shelter!

Correct, unfortunately that is a limitation I have because that is all that is produced by the manufacturer.
I am currently in communication with the manufacturer about producing an indicator for the next 16 levels lower, but fear it will drastically increase the price of the kit to have them made. I want to keep the price as low as possible.
Edit: The additional custom 16-level indicator would require more than a $3,000 investment on my part, so I am not proceeding with production of this strip. Instead, I am offering the additional lower temp 7-level indicator for $0.65.
I live near Chicago. :O)
If you wanted to read lower temps, I can offer another additional smaller 7-level indicator for an small additional cost. It's range is 32°F through -22°F (see image below). The size is 0.5" x 1.77" and is also self-adhesive.
With this indicator one can make a best "exact temp" guesstimate by looking at the color variation. Green is the exact temp and blues are slightly lower, greeny gold slightly higher. i.e. – if the 32°F box is greeny gold and the 23°F box is blue, you can guesstimate the temp somewhere in between that range. This can be estimated more easily with use as you take note of the color variation through temperature transitions.
