Details

Red spirit-filled thermometers provide increased safety and economic pricing. They contain a kerosene-based column with red dye, which is significantly safer than mercury. These thermometers all have 6 to 7mm outer diameters, and the bulbs have equal or smaller diameters than the stems.

Partial immersion thermometers are useful if you have a shallow container which holds the substance to be measured. These thermometers have a small indicator ring that denotes the depth to which the thermometer should be submerged to obtain an accurate temperature reading.

Full immersion thermometers need to be submerged deep enough so the desired temperature is at the meniscus. For example, if you wish to measure the temperature of a hot water bath to make sure it is 100°C, then you need to submerge the thermometer up to the 100°C mark.

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

John C.

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
