Product Description
The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals that can restrict the flow of fuel. The temperature of the fuel in the aircraft tank normally falls during flight depending upon aircraft speed, altitude, and flight duration. The freezing point of the fuel must be lower than the minimum operational tank temperature. The test determines the temperature below which solid hydrocarbon crystals form in aviation fuels. The sample is cooled with continuous stirring in a Dewar-type sample tube until crystals appear.
*** REQUIRES REFRIGERATED FREEZING POINT BATH, FREEZING POINT APPARATUS, STIRRER MOTOR AND ASTM 114C NON-MERCURY THERMOMETER. Also available are two moisture proof collars: Type A Nitrogen Collar AND Type B collar modified for Glass wool, dehydrating agent (silica gel) ***
Features and Benefits
~ Improved design with enhanced performance and safety features
~ Operating range to -100°F (-73°C)
~ Microprocessor PID digital temperature control
~ Dual digital displays show setpoint and actual bath temperature
~ Selectable temperature scale - Fahrenheit or Celsius
Redesigned constant temperature bath for freezing point determinations on fuel samples at temperatures as low as -100°F (-73°C). Accommodates K29700 Freezing Point Apparatus and accessory stirrer. Microprocessor PID circuitry provides precise, reliable temperature control within ASTM specified tolerances. Simple push button controls and dual digital displays permit easy setting and monitoring of bath temperature. The bath medium is contained in a clear, evacuated Dewar flask, and glare-free fluorescent backlighting provides excellent visibility when working with the freezing point samples. Air-cooled hermetic compressors provide efficient operation with the use of CFC-free refrigerants. Temperature control uniformity is assured by means of a motorized stirrer which provides complete circulation without turbulence. Cabinet construction is polyester-epoxy finished steel with a chemical-resistant composite top surface. Working (top) surface includes port and mounting plate for K29700 Freezing Point Apparatus and accessory stirrer. The bath rests on adjustable leveling feet.
Temperature Range: Ambient to -100°F (-73°C)
Temperature Control Accuracy and Uniformity: Exceeds ASTM requirements throughout the operating range
Display: 0.1°C/°F resolution
