Glass Bead Bottle MSDS
So far so good. It looks like it has cured my temp alarm warnings. I use iMonnit temp sensors which are wireless for a number of our freezers. One of them was alarming out on me at almost every Defrost cycle every 6 hours. Going over my 12F limit before I'm getting a text message on my phone. At the end of the chart, you can see the temp cycles as the freezer cycles on and off which are more level and then shorter temp spikes on defrost staying below 3F.
Installed the temp probe into the middle of the bottle which was easy enough and then mounted to the wall with a simple strap mount I made to screw onto the wall. Would have been nice if there was a mount made for the bottles as you don't want it to just dangle in the air. I wasn't sure which bottle size I needed. But this smaller one seems to work well. It evens out the temp changes better with a faster response than I think the larger bottle would respond. I don't want too long of a delay. If the freezer breaks down, I didn't want too long of a delay warning. I just wanted milder spikes. This temp probe is set to report every 15 minutes.
I may get some more of these for my other freezers. This is a secondary temp Monitor and quicker and easier to just take a look on my phone All our freezers are set to a normal -12F temp.
Use with probes to buffer readings against temporary air temperature shifts caused by opening doors or loading coolers. Ideal for VFC, pharmacies, doctors offices, walk-in coolers and other locations that experience drastic, temporary temperature changes.

Working better than expected so far.

Why did you choose this?
what's the size of the glass beads? can this be used with temperature probe ultra low temperature (-80C)?
The glass beads are very, very tiny. This can be used with ultra low temperatures.
Where are instructions? Do you have to punch a hole in the compression sleeve? Seems that after probe goes in there will be space for the glass beads to fall back out...the probe tip is larger than the cable.
The best probe to use with this glass bead bottle is a wire probe, for the exact reason you pointed out. If you are using a probe that has a transition, only insert the probe portion.
Here are some type k wire probe options: https://www.thermoworks.com/shop/products/probes/type-k-thermocouple/wire/
I'm curious about the usable temperature range. Can it be used at -90 degrees?
The Glass Bead Thermal Buffer Bottles will be fine at that temperature range. Finding the probe to operate in this range will offer a bigger challenge. This probe operates in the range of -112 to 392°F (-80 to 200°C)

I'm curious about the material of the bottle (e.g., HDPE). Also, what is the temperature range this product can be used in? (e.g., -100 ~ 200°C)
The bottle is polyethylene. The product use will be limited by the the bottle, but they are typically used in refrigerated uses. It may best to speak with the Sales team if you have application specific needs.
When would I want a 200g over the 50g? Just trying to eliminate huge thermometer temp spikes in my household refrigerator and freezer.
The 50g bottle will be what you want for your household refrigerator and freezer. The bigger bottle will take longer to change temperature.
what size probe can be used with this bottle?
Most probes will fit in this bottle and are viable to use as the sensor is always at the end of the probe. Ideally, you'll want a shorter probe so that it's more compact.
Does this come with compression fitting cap to fit the sensor probe?
Yes, this comes with a compression fitting cap to hold the probe within the buffer bottle.
Are they legal to use, i.e. glass in the food production areas and all? Also, we are using probes with cooking oil in them as a buffer now - and one or two inspectors pointed out that using buffer of any sort would be preferable.
There is no issue using these glass beads in food production areas.
does it come with a bracket?
This does not come with a bracket.
What size glass beads are being used in the bottles?
The beads are approximately 1mm.
asked to order it by someone oelse
Need to replace sensor probes in -80C freezer
Fore more accurate temperature readings in walk-in/reach in coolers
Serves my purposes for refrigeration buffers!
