MEASURING INSTRUMENTS
Product information
You can only purchase our Rau DPG07 and DPG02 measuring devices from specialist dealers.
In our specialist dealer search you will find a list of all specialist dealers and online dealers with Rau products.
Our two measuring devices DPG07 and DPG02 are equivalent in terms of quality and precision, and the scope of testing is almost identical. Our DPG07 offers the great additional advantage of saving the test data on an SD card. This allows you to carry out several measurements, manage them in the office and also print them out as a ready-made, informative A4 data sheet. With the special accessory WPS radio, wireless data transmission is possible in inaccessible or difficult test situations. You can find a more detailed comparison of our two measuring devices on our measuring device comparison page.
With the two Rau measuring devices DPG02 and DPG07, you can test natural gas, liquid gas, water, heating and waste water pipes. The scope of testing covers load and leak testing and serviceability determination (leakage rate). The exact list of all tests according to the respective measuring device can be found on the product detail pages of our DPG07 TOUCH and DPG02 TOUCH.
Due to the high demand for improved electronic measuring devices with touch displays, our older models have been removed from the range. These have the unbeatable advantages of a larger test scope, an exact output test value and a printout as legally compliant proof.
