Testing dipstick

A testing dipstick is usually made of paper or cardboard and is impregnated with reagents that indicate some feature of the liquid by changing colour. For example, medical dipsticks are used to test urine samples for haemoglobin, nitrite (produced by bacteria in a urinary tract infection), protein, glucose and occasionally urobilinogen or ketones.

Measuring dipstick

Dipsticks can also be used to measure the quantity of liquid in an otherwise inaccessible space, by inserting and removing the stick and then checking the extent of it covered by the liquid. The most familiar example is the dipstick in an internal combustion engine, which is a metal strip or thin flexible coil used to measure the quantity of fuel or lubricating oil. Generally the procedure for reading the dipstick is to remove it, clean it with a rag or paper towel to provide a fresh surface for the liquid to contact, then reinsert it. The stick is then removed once more and the level is compared to markings on the dipstick which indicate the required level. A car's transmission fluid sometimes has a similar though usually shorter device. A Firkin is an old English unit of volume. ... A millimetre (American spelling: millimeter, symbol mm) is an SI unit of length that is equal to one thousandth of a metre. ...

A dipstick can also be used to check the amount of beer remaining in an ale cask. The stick (generally stainless steel or brass) is made of thin square rod or flat strip, and is inserted through the small hole in the shive on the top of a horizontal cask. If double-decker racking is used a flexible strip may be useful, since casks on the lower rack might not have enough headroom for a rigid rod to be inserted. Cask ale is the term given to unfiltered and unpasteurised beer which is conditioned and served from a cask without additional pressure. ... A barrel is a hollow cylindrical container, usually made of wood staves and bound with iron bands. ... The top of a cask, showing an unopened wooden shive with a plastic seal. ...

Ale dipsticks can be bought or home-made. Because of the round shape of a cask, the intervals between marks vary along the length of the stick. A home-made dipstick for a standard firkin (9 gallons) can be made using the table on the right. A Firkin is an old English unit of volume. ...
