Original product description
The JF4929A is a laboratory instrument for determining the dropping point of lubricating grease. During testing, grease is placed in a test cup and heated under the conditions specified by the selected method until it reaches the defined degree of fluidity.
The listed applicable methods are ASTM D566, ISO 2176, and GB/T 4929. The instrument uses a transparent glass cylinder as the heating-bath body, allowing the test area to be observed during operation.
An electric heating bath with a stirrer, stainless steel heater, adjustable heating power, LCD digital display, and voltmeter indicating the heating state are included in the described configuration. Two working positions allow two samples to be tested at the same time for parallel measurements.
The stated temperature-control range is 25–300°C, with stated control accuracy of 0.1°C. Rated machine power is 800 W. The listed supply options are AC 220 V or 240 V at 50 or 60 Hz. The instrument measures 210 × 220 × 390 mm and has a stated net weight of 5 kg.
Safety provisions are described for overheating and low water level. The housing is made from cold-rolled steel plate with an electrostatically sprayed surface, while the grease cup is described as chrome-plated brass.
Procurement questions to confirm: Buyers should verify the exact model designation because the supplied information also references JF4929, confirm the required voltage and frequency before ordering, and request confirmation of the supplied accessories, grease-cup dimensions, calibration documentation, and current conformity to each required test method.
Also confirm packing dimensions and gross weight because the shipping data differs substantially from the instrument’s stated size and net weight.
Customization is stated as available, with a one-year warranty and lifetime online technical support;buyers should confirm the precise scope and delivery documentation for their order.
