Hydrometer ASTM 118H 1,350-1,400:0,0005 is a specific-gravity hydrometer for laboratory measurement of liquids in the upper part of a common ASTM density series. The scale runs from 1,350 to 1,400 with a fine division of 0,0005, allowing careful reading of specific gravity during routine checks. The ASTM 118H designation links range and graduation so instruments can be chosen consistently alongside neighbouring hydrometer types. Supplied as 1 pc at a net weight of 0,113 kg, it is convenient to store, deploy and replace on the laboratory bench. The glass float is immersed in the sample and specific gravity is taken from the stem scale at the liquid surface according to standard hydrometer practice. Typical tasks include density assessment of solutions, process liquids and related samples that fall inside the 1,350–1,400 window. Clear range labelling supports organised multi-instrument sets used in quality control and method development. This hydrometer from manufacturer Witeg addresses classical buoyancy-based specific-gravity work where an ASTM-format instrument is preferred. It serves educational, industrial and research laboratories that maintain ASTM hydrometers for defined density intervals.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Areometer ASTM 118H 1,350-1,400:0,0005
What is this article?
Areometer ASTM 118H 1,350-1,400:0,0005 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Hydrometers, inside Density & viscosity measurement, in Instrumenten.
A hydrometer floats in a liquid and the stem reading is the density or a related scale such as Brix. The liquid has to be at the temperature printed on the stem, or a correction is required. A chip on the stem changes the reading. One hydrometer does not cover every density.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
