Economy thermometers have a yellow enamel backing and a diameter of 6-7mm. Economy thermometers include a plastic cap and ring. The cap has a non roll form. It resists in the hot liquid for 30 seconds at 150°C (302°F). There is a window in front of the expansion chamber enabling the user to verify if there is any column separation.

The temperature scale is printed and fused in the glass with a special process, the graduation resists to all chemical products except fluoridric acid and hot soda because these 2 products attack the glass. The numbers are printed every 10 °C and the graduation is much larger than usual enabling an easier reading for the user.

These thermometers are available in partial or total immersion. When the thermometer is calibrated for partial immersion, there is a line printed around the thermometer at 76mm with a clear mention: "Imm. 76mm”. This mark enables the user to immerse the thermometer to the correct depth.

The thermometers are packed in a strong plastic packaging with a square form, non roll. Economy thermometers cannot be supplied with Calibration Certificate.
