Our test conditions apply. The conditions in detail:
 
The rental period is five daysupon receipt of the test device. After this time, please send the device, including accessories and packaging, back to us with the enclosed DPD label .

The offer can only be used within Austria(for German customers there is a loan option from our partner meerwasser-hardware.de)
Note that you are using the device's sensorrinse with osmosis water after useso that we can enjoy it for a long time. the sensorNotwipe (with cloth, kitchen roll, handkerchief, etc - only rinse with osmosis water!)
The sensor holder, pleaseNotdisassemble
We will charge for a late return 12 euros per day including VAT. This late fee cannot be applied to future orders. Don't worry, you don't pay for mistakes made by the shipping service provider, we use the tracking to see when the PAR meter was abandoned.

In the event of loss or damage, the regular purchase price of the device minus the rental fee applies.
 
Product Information
The MQ-510 quantum meter is designed for underwater PAR measurements and already applies the sensor's diving effect correction factor to the displayed results via the firmware. The meter consists of a waterproof quantum sensor connected to a handheld meter via a waterproof cable. The waterproof sensor consists of a blue-enhanced silicon photodiode and  optical filters with a rugged, anodized aluminum housing with an acrylic diffuser. The underwater quantum sensor is typically used in marine aquariums where corals are grown.
 
Note: The handheld meter is not waterproof, only the sensor and cable are waterproof. The device must be protected against splashing water! If the device is damaged due to improper handling, we reserve the right to charge the new price of the device.
