Product Description
Molten samples of maleic or phthalic anhydride are compared with Platinum-Cobalt color standards for determining sample purity and the qualitative stability in the presence of contaminants. High color content normally indicates contamination.
Features and Benefits
~ Conforms to ASTM D3366 specifications
~ Redundant over-temperature protection circuitry
~ Microprocessor-based temperature controller
Electrically heated aluminum block features a microprocessor-based temperature controller with over- temperature protection circuitry and a dual LED temperature display. The heating unit provides temperature stability, heating rates, and minimal temperature gradients which exceed ASTM specifications, and is housed in an insulated steel cabinet with a chemically-resistant painted finish. Up to six samples can be tested at a time using Nessler tubes. Visual color comparisons are made against solutions of Platinum-Cobalt color standards or measured with a K13250 Portable Automatic Colorimeter or a K13500 Automatic Colorimeter.
Testing Capacity: 6 samples
Maximum Temperature: 260°C (500°F)
Temperature Control Stability: ±0.05°C (±0.1°F)
