The Portable Closed Flexi-Dip measuring tape is a battery-operated electronic unit that is totally gas-tight. When installed in a vapor-control valve mounted on a storage (cargo) tank, it forms a tightly sealed system that prevents toxic vapors from escaping and creates a closed gauging system for that tank. The tape is marked in metric or English units and is anti-static coated (as is the sensor). In addition, the tape is color marked to make tape direction and motion easily seen and to ensure full rewind position. A coiled grounding cable with large alligator clip is standard. This closed system is recognized by many worldwide regulatory bodies as equivalent to a fixed gauging system as long as the tape remains in the valve from the beginning until the end of loading or discharging of the tank.

This grouping of hydrometers are not ASTM – but are enormously popular in the same applications as the ASTM 21 through 39H hydrometers. All are 165mm in length, graduated in 0.2 API divisions, and made to the same demanding tolerances as ASTM hydrometers. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
Approximately 190mm (7-1/2″) Length. Thermometer in body. Not ASTM designated, but made to similar specifications. Popular due to the smaller sample amount (approx. 6 ounces) ounces needed to obtain a reading. Made to the same demanding tolerances as ASTM hydrometers. Accuracy: +/- 1 scale division. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
Eight hydrometers 500-231 thru 500-238 below, covering the range from .700 to 2.000 A thermometer range 0/230 °F is included. Supplied in a sturdy foam cushioned case with carrying handle. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
.070° Specific Gravity ranges, 6″ length. Made to the same exacting standards as ASTM hydrometers, these units have found wide application due to their slightly longer, overlapping ranges. Accuracy to +/- .001 Specific Gravity. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
.070° Specific Gravity ranges, 13″ length. Made to the same exacting standards as ASTM hydrometers, these units have found wide application due to their slightly longer, overlapping ranges. Accuracy to +/- .0005 Specific Gravity. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
