Pensky Martens Apparatus
Flash & Fire Point Apparatus / Pensky-Martens Apparatus
Flash & Fire Point Apparatus / Pensky-Martens Apparatus For determining the flash point of fuel oils and lubricating oil, bitumen other than cutback bitumen and suspension of solids in liquid, having a flash point above 49° C.
The oil cup is made of brass, fitted with a thermally insulated lifting handle. The cup lid, with insulated handle, is fitted with two opposite wedge cams, which engage under pillars secured to the cup flange. This feature facilitates easy removal of the lid by rotating the handle a few degrees to disengage the cams. The shutter opening mechanism is designed for smooth operation and is operated by a spring handle with a knuled knob. A flame exposure device (Gas test jet assembly) is mounted over the lid. The manually operated stirrer has flexible has a flexible shaft. The cup assembly is positioned in a cast iron air bath, fitted with a chrome plated brass top. The air bath is mounted on an upright which serves as a gas manifold. Valve controlled supply lines for adjustable flames are provided with pilot and test flames. An additional line with control valve supplies gas for use with open flash clip, in accordance with IS: 1448 (P: 66), IS: 1209, A ring support is provided for the lid when not in use. Electrical heating, with gas test jet and electric heater with energy regulator. 220 V, 50 Hz, Single Phase, AC. Reliable and Accurate Flash Point TestingDesigned for conformance with industry standards, the Pensky Martens Apparatus delivers precise flash point measurements for petroleum products. Manual operation ensures user control, while the analog thermometer and regulated electric heating provide consistent, reproducible results up to 370C. Its robust design, with either brass or stainless steel sample cups and cast iron base, guarantees longevity and reliable performance in demanding laboratory environments.
Flexible Operation and Enhanced SafetyUsers can choose between flame or electric spark ignition, adapting to different testing protocols. The protected heating element, insulated handle, and manual control system safeguard operators during use. With a sample requirement of approximately 75 ml per test and a cup capacity of up to 500 ml, the system balances efficiency and safety for daily laboratory processes.
FAQs of Pensky Martens Apparatus:
Q: How is the flash point determined using the Pensky Martens Apparatus?
A: The apparatus allows the sample to be gradually heated in a test cup while being stirred. The flash point is identified by introducing a test flame or electric spark at intervals, and recording the temperature at which a flash occurs. The analog thermometer provides temperature readings with a 1C resolution.
Q: What are the primary components included with the equipment?
A: Standard accessories comprise the thermometer, test flame device, sample cup, electric heater, and all necessary mounting hardware for bench top placement. The lid assembly is equipped with supports and mechanisms required for stirring and temperature measurement.
Q: When should this apparatus be used in petroleum testing laboratories?
A: It is ideal for precise flash point measurement during quality control, safety analysis, and compliance testing of petroleum products, following relevant national and international standard test procedures.
Q: Where can the Pensky Martens Apparatus be installed for operation?
A: Designed for bench top mounting, it is suitable for use in laboratory settings where stable and safe operation can be ensured. Its compact dimensions accommodate most laboratory workspaces.
Q: What safety features does the Pensky Martens Apparatus provide during operation?
A: The apparatus incorporates a protected heating element, insulated handle, and manual operation controls to minimize potential hazards. It is built to withstand high temperatures securely, ensuring user safety throughout the testing process.
Q: How does manual and electric operation benefit users?
A: Manual stirring and control give users flexibility and precision, which can be critical for certain testing protocols. The electric heater with energy regulator also offers steady heatingensuring accurate, repeatable results while accommodating different operational preferences.
Q: What is the process for preparing a sample for flash point testing?
A: Approximately 75 ml of the petroleum product is poured into the test cup. All accessories must be correctly assembled, and the sample is heated gradually with continuous stirring. The test flame device is used to periodically check for a flash, following standardized procedures.
