Returns

 

The legal regulations for environmental protection and our personnel re-
quire  that  devices  which  are  sent  back  which  have  come  into  contact 
with liquid are handled without risk to people or the environment. 

 

 

 

If you send a device back to us for inspection or repair, we must request that you 
strictly observe the following requirements: 

 

On the GHM homepage under 'Downloads/forms' a return shipment form can be 
downloaded. 

 

The repair can be performed quickly and without call-back questions if: 

 

1. a filled-in form is provided for each device, 

 

2. the device has been cleaned and packaging which prevents damage to the   
    device 

 

3. a safety data sheet for the measuring medium is affixed to the outside of the 
    package, if the device has come into contact with a critical substance. 

 

10. 

Disposal 

Separation by material and recycling of device components and 
packaging must take place when the device is disposed of. The valid legal 
regulations and directives applicable at the time must be observed. 

The device may not be disposed of with household waste. If the device should be 
disposed of, return it to us with the return shipment form filled in the chapter 
'Returns'. We will then arrange for the proper disposal.
