Glycol bottles are a great way to stabilize your temperature readings when using a probe
The 60mL of propylene glycol can be used to mimic the substances you are measuring
These bottles are compatible with any K TC beadwire probes
A common use of the glycol bottles is to stabilize a temperature reading in a refrigerator that is opened and closed often
The air temperature in the refriegerator (or any space) may change faster than the temperature of the material you are monitoring and the glycol bottles may better represent the true temperature of the monitored materails
