In the central control room of large-scale refining and chemical bases, third-party lubricant testing and certification agencies, and regional electrical testing laboratories, "sample pressing and queuing" is a major challenge that is normalized.

According to the national standards GB/T 7305 and GB/T 7605, the determination of demulsification degree of an oil sample involves three time-consuming steps:

Preheating and constant temperature: After filling the measuring cylinder with 40ml of oil and 40ml of water, immerse it in a water bath at 54 ℃ (or 82 ℃) and maintain constant temperature for at least 10 minutes;

Intense stirring: high-speed mechanical stirring for 5 minutes;

Static separation observation: observe the time for the volume of the emulsion layer to dissipate to 3ml by standing still, with a maximum observation period of 30 minutes.

If the laboratory uses old-fashioned single hole and double hole testers that can only insert one or two samples, it will take nearly an hour to measure each sample. Faced with more than ten batches of oil samples to be tested every day, the laboratory technician cannot finish them even with overtime work.

The HZ-1542 anti emulsification tester developed by Baoding Huazheng Electric Manufacturing Co., Ltd. is specially designed to solve the pain point of "large batch and high-throughput" detection!

4-hole independent channel layout, multiple fold increase in inspection flux

HZ-1542 adopts a high specification four hole integrated constant temperature water bath platform:

Simultaneously maintain a constant temperature for 4 sets of samples: The spacious water bath and constant temperature bath are designed with 4 precise positioning holes, and 4 100ml specialized measuring cylinders filled with oil-water mixture can be immersed in the bathtub at the same time for constant temperature balance, completely eliminating waiting in line for preheating;

Step by step efficient assembly line operation: The laboratory technician can start the automatic mixing process for different hole positions in sequence. While the first sample is stirred and automatically lifted, the second sample can start mixing immediately, forming a seamless "assembly line" testing rhythm;

Up to 4 independent timing tracking channels: The instrument control system supports independent timing tracking of the separation process of 4 sample wells. Which sample's emulsion layer drops to 3ml first, press the corresponding channel to lock the result, without interfering with each other!

Double the efficiency of daily testing, helping laboratories to quickly output data

The sample batch that originally took a whole day to complete can be fully tested in just half a working day using HZ-1542:

Significantly shortened the reporting cycle for external oil samples or incoming oil materials;

Effectively reducing the waiting time for large-scale unit shutdown and maintenance;

The HZ-1542 can be regarded as a "productivity multiplier" for modern large-scale oil product laboratories, with four holes in one go and a calm response!
