Main technical features
1.The instrument adopts double units working mode, can do test for one sample as well as two samples which having the same specification or different specifications.It highly improves the work efficiency.
2.It adopts two groups of independent digital temperature controller, heater, electric stirrer to constitute two constant temperature baths. Each bath temperature can be adjusted and controlled independently.The temperature in the bath is uniform,can fully meet the requirements of test.
3.It adopts special heating furnace to ensure the safety of test. Heating power can be continuously adjusted to meet the requirements of test.
