BN-025 engine antifreeze corrosion tester

BN-025 engine antifreeze corrosion tester

I. Overview

1. This instrument is developed according to the SH/T 0085 standard.

2. Process the six typical metals used in the engine cooling system into test pieces, weigh them and connect them into test strips, then completely immerse them in 750mL , air flow 100mL ± 10mL/min samples, high boiling point coolant and The rust inhibitor was tested at 88 °C ± 2 °C, and the low boiling point coolant was tested at 71 °C ± 2 °C for 336 h ± 2 h . After the end of the test, the test piece was taken out, and after being cleaned, it was weighed again, and the corrosion was evaluated by the mass change value before and after the test piece after the test.

Second, structural characteristics

1. This instrument is a desktop structure as shown in the figure.

2 , using 7 -inch LCD screen, touch screen control.

3 , friendly interface, full Chinese display, real-time display of the working state of the instrument. Such as current temperature, running time, water valve status and other information.

4. The instrument has two independent metal baths, which can control different temperature points separately. The temperature points can be set arbitrarily, with PID self-tuning function.

5 , with temperature correction.
