2. Intended purpose24

2. Intended purpose

This chapter gives the areas of application for which the

product is intended.

Use the product only for those applications for which it was

designed. Ask Testo if you are in any doubt.

The testo 512 is a compact digital manometer with

temperature compensation for measuring the positive and

negative over-pressure and differential pressure of non-

aggressive gases. With the versions 2hPa, 20hPa and

200hPa, flow velocity can also be measured via a Pitot

tube.

The product was designed for the following

tasks/applications:

· Measurement on heating, ventilation and air conditioning

systems

· Customer service and maintenance work

The product should not be used in the following areas:

· Areas at risk of explosion.

· Diagnostic measurements for medical purposes
