Satellites operate in the vacuum and cold of space, therefore they have to undergo extensive testing here on earth. A few months ago we received a large order for a range of Teflon PFA insulated T-type thermocouples from researchers and manufacturing engineers working on satellites for a large constellation. T-type thermocouples are especially suitable for measuring cold temperatures and are frequently used in cryogenics. And the PFA plastic insulation is very stable at cold temperatures, though …

Recently I was contacted by a professor at a Wisconsin University. He is researching bumblebees and wanted to measure and record the temperature inside their nests. Due to the need for more accurate measurements we settled on T-type thermocouples and to minimize the impact from the insulation we used a teflon PFA insulated wire, which is very inert and will lot leach any chemicals. We made these thermocouples in a range of lengths, up to 5 meter (15 ft) long.  Do you have a special measurem …

Over the last year the price of nickel, a main input for K-type thermocouples, has increased tremendously. The price had slowly increased by about 75%, and over the last few weeks then jumped to and 160% increase year over year. Add to that the increased cost of shipping, which tripled over the last year and probably will go up even more with the rising gas prices. This means that the prices for all thermocouples will increase over the coming weeks. The impact will vary, depending on how much ni …

During the Covid-19 pandemic we suspended almost all international shipments of thermocouples and thermocouple thermometers. Now that the situation normalizes and international shipping speeds up, I decided that we can start resuming shipments to Canada. Please still expect longer than normal shipping times, but in most areas the packages should arrive in 2-3 weeks.Please contact me for all other international shipments, I will decide case by case if a shipment is possible.

I get more and more requests for ultra thin thermocouples, both in K-type and T-type versions. Customers need them in low heat loss or fast reacting temperature measurements. In the past our thinnest wire was AWG30 (0.255 mm, or about 10 mils). We now carry some AWG36 wire (0.127 mm or about 5 mils) with an especially thin dual insulation. Very soon we will offer pre-made and custom thermocouples in this new thin gauge wire.In the picture you see the AWG30 wire with single insulation compared to …
