Why Medical-Grade Power Supplies Are Better for Our Aquarium Devices:

1. Superior electrical safety — medical-grade power supplies have a much lower leakage current (typically <100 µA) and stricter isolation (2x MOPP), reducing the risk of electric shock — especially critical in wet environments like aquariums.

2. Stronger isolation standards, certified to IEC 60601-1 — these supplies offer enhanced protection against faults, including double insulation and increased creepage/clearance distances.

3. Higher reliabilitydesigned for life-critical applications — medical power supplies are built to stricter standards for long-term reliability and thermal endurance.

4. Market advantage — medical certification signals premium safety and professional quality. It builds customer trust and eases regulatory approval in global markets.

5. Perfect fit for aquatic use — though not used on humans, our products are immersed in water, making the medical-grade safety level ideal, and a clear upgrade over IT or household-grade power supplies.

Offset Magnet Osmolator® 3

The offset magnet allows the sensor of the Osmolator® 3 (3154.000) and Osmolator® 3 nano (3151.000) models to be precisely adjusted upwards within a range of 1 to 18 mm (0.04"–0.71") (5). Thanks to the special design, the sensor is positioned 10.7 mm (0.42") from the glass pane (6), which makes it easy to install it even on aquariums with a protruding frame.
For frames with a height of up to 21.4 mm (0.84"), the sensor can be mounted using two offset magnets. This solution is suitable for glass thicknesses of a maximum of 12 mm (1/2").
Caution: Please note the maximum glass thickness to ensure safe and stable installation!
