In many petrochemical inspection centers and lubricating oil quality inspection rooms, the laboratory technician often finds it time-consuming and frustrating to do a GB/T 12579 lubricating oil foam characteristic test.

According to the standard specifications, three complete stages (Sequence I, II, III) must be completed to determine the foam characteristics of oil products:

Phase 1: Blow air at a constant temperature of 24 ℃ and keep the timer still;

Phase 2: Heat the new sample to a high temperature of 93.5 ℃ and repeat the blowing test;

Phase 3: After cooling the high-temperature sample to room temperature, place it in a 24 ℃ bath again for retesting.

If the laboratory uses old single tank instruments, the laboratory technician will have to heat the tank to 93.5 ℃ with great effort after completing each stage, and then have to wait for a long time for the tank to slowly cool back to 24 ℃, or manually change the water frequently. Completing a batch of samples often takes up an entire day.

The double groove independent design of Baoding Huazheng Electric HZ-1024 lubricating oil anti foam tester completely ended the pointless wait of "heating and cooling back and forth"!

Bow left and right: standby at both low temperature of 24 ℃ and high temperature of 93.5 ℃

HZ-1024 completely eliminates the outdated design of single slot shifting and innovatively adopts a dual water bath integrated parallel architecture:

Left low-temperature bath: Equipped with a dedicated PID temperature controller and an external high-efficiency portable refrigerator, the water bath can be stably locked at 24 ℃± 0.5 ℃ even in hot summer days when the room temperature reaches over 30 degrees Celsius;

Right high-temperature bath: Equipped with a high-power precision heating system and an independent stirring motor, the water temperature is firmly stable at 93.5 ℃± 0.5 ℃.

Each double slot is equipped with an independent digital temperature control instrument, an independent mixing motor, an independent power switch, and an independent countdown buzzer alarm.

Pipeline operation, doubling efficiency

With dual slot independent hard core support, the entire experimental process flows smoothly like clouds and streams:

Low temperature 24 ℃ blowing and stationary stage are carried out calmly in the left slot;

The preheated 93.5 ℃ high-temperature sample can be directly injected with gas for testing in the right slot synchronously;

The entire testing cycle completely eliminates the waiting and switching time between different temperature zones, and multiple batches of samples are cross connected for continuous operation, resulting in a more than doubling of daily testing throughput!

Say goodbye to the long wait and refuse to be flustered. HZ-1024 makes the complicated and standardized high and low temperature foam test orderly, efficient and leisurely.
