★ Superior design:

Curved shape and surface spraying treatment, high-quality appearance, and flat non reactive handle, easy to operate, safe and reliable.

★ Large observation window with wide and bright field of view:

Adopting a three-layer vacuum coating window and Philips energy-saving fluorescent lamp, there is no need for wipers to defog, maintaining clear observation effect, and the condition of the test sample can be observed at any time.

★ Water electricity separation ensures safety:

The separation of the humidification system pipeline from the power supply, controller, and circuit board can avoid the impact of pipeline leakage on the circuit and improve safety.
