- ASTM D892
- IP 146, ISO 6247
Construction Details
- The complete assembly consists of following parts and accessories.
1) Foaming Bath Apparatus - (Glass jar with one Test Cylinder 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.
