For taking various types of samples on oil and chemical tankers where closed or restricted sampling systems are used. The Ed Martin Multi Level Sampler uses a modular design that allows the operator to change the sampler functionality by simply exchanging a few components. Each sampler comes standard with an adjustable opening top cap, a low-pressure bottom cap for taking zone or running samples, and a high-pressure bottom cap and trip funnel for obtaining RVP samples. The supplied 12-inch barrel, 16-inch barrel, and barrel coupler give the operator the ability to adjust the sampler volume capacity to fit their needs. Additional barrels and couplers can be used to increase capacity. All components are available individually upon request. Made from non sparking brass or stainless steel for durability.
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.
