Standard length ASTM hydrometers and thermometers are too long to fit the holders if it is desired to leave these instruments in place with the lid closed. For customers who want to leave them in place, we offer special short models as follows.
These hydrometers have shorter scales than are required for standard ASTM models. For example, in the metric models, the graduations are 2.14 mm apart for 1 KG instead of 2.59 mm for standard hydrometers. These thermometers have the same graduation spacings as for standard ASTM thermometers such as 12C and 12F but the range has been shortened so they will fit in the Aljac Sampler.
