FOAMING CHARACTERISTICS OF LUBRICATING OIL-ASTM D892-(TWO TEST CYLINDERS)-(SINGLE JAR)-

Complies with following International Standards

ASTM ‑ D892, IP ‑ 146, ISO ‑ 6247

Construction Details

The complete assembly consists of following parts and accessories.

1)  Foaming Bath Apparatus - (Glass jar with TWO Test Cylinders and combined Heating & Cooling arrangement)

• Consists of constant temperature transparent glass heating jar bath
• Heating glass jar will be of Heat resistant material having height of 450 mm and Diameter of 300 mm
• The transparent heating test bath will be provided with top cover
• Tank cover will be having one hole of Ø 125 mm, which allows 1000 ml cylinders to get through it
• The heating glass jar is transparent and clear enough to permit observation of the graduations on the cylinder.
• Tactfully designed Stainless steel clamps, incorporated within tank cover, to hold the test cylinders in place.
• Microprocessor PID control provides quick temperature stabilization without overshoot and the bath is protected by  an over temperature control circuit.
• Dual LED display provides actual and set point temperature values in °C/°F format.
• Cooling coil is provided in the same bath for circulating cooling water from the external chiller to conduct the foaming operation on  24 °C temperature. (External chiller has to be purchased optionally at extra cost).
• Heating supplied by an armored stainless steel heater in the test bath, to conduct the test on 93.5 °C
• Automatic boost heating
• Automatic high temperature & low liquid level safety cut‑off.
• Supplied with stirrer to maintain uniform temperature distribution throughout the bath.
• Bottom base, houses a MICROPROCESSOR BASED DIGITAL PID controller with over‑temperature alarm and probe PT ‑ 100 temperature sensor along with air compressor pump for supplying adequate air through flow meter to diffuser ball.
