Economy Thermometer

• The glass

The glass used has a diameter of about 6-7 mm. The colour of the glass is standardized in yellow giving a much better reading than the white back, mainly for mercury filled thermometers. This is a quality choice even if the white glass is usually less expensive than yellow.

• Immersion

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.

• Bulb size

The bulbs have different sizes even for the same reference article because the diameter of the internal bore can have some variations. We detect variations of the bore to within 0.01mm and we separate according to bore diameter. In order to compensate these variations, we change the size of the bulb in order to keep the correct volume

• Scale

The numbers are printed every 10 °C, and the graduation is much larger than usual enabling an easier reading for the user. The negative temperature numbers are printed vertically while the positive temperature numbers from 0° C (32°F) are printed horizontally.

The scale is printed very dark in order to have a clear reading. The graduation of Promo Lab is printed and fused in the glass with a special process. (Note concerning thermometers from the competition: some thermometers, mainly those for high temperatures, are still engraved and the ink does not resist to solvents or other chemical products).

The graduation becomes unreadable. The graduation resists to all chemical products except fluoridric acid and hot soda (to a lesser extent) because these 2 products attack the glass.              

• Cap

ALLA FRANCE has developed a special cap in place of a glass ring. The cap has a non roll form. It resists in hot liquid during 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  

• Packing

The thermometers are packed in a strong plastic packaging with a square form, non roll. 10 thermometers of the same article are packed inside a white cardboard box.Two labels on the box indicate:

- The reference and a GEN code

- The temperature   and range the subdivision       

- The liquid filling

T 001                         Red liquid filling

T 002                        Mercury filling
