Instruments offer precise pressure measurement

Testo has recently launched two new highly precise pressure measurement instruments that can be used for differential, relative and absolute pressure measurement.

Testo has recently launched two new highly precise pressure measurement instruments that can be used for differential, relative and absolute pressure measurement.

The Testo 521 offers an internal differential pressure sensor with a measuring range of 0 to 100hPA.

The Testo 526 offers an internal differential pressure sensor with a measuring range of 0 to 2000hPA.

Both instruments offer accuracy of up to 0.05% of the limit value making them ideal for measurement of critical processes that require precise measurement.

Both instruments are also equipped with two probe inlets to connect further probes for measuring temperature and pressure, making the instruments suitable for a wide range of applications.

Both instruments are available in two accuracy classes: the Testo 521 with 0.2 or 0.1% of limit value, the Testo 526 with 0.1 or 0.05% of limit value.

All units can be fitted with a range of additional probes: a differential pressure probe up to 2000hPA; an absolute pressure probe up to 2000hPA; a relative pressure probe up to 400bar; and temperature probes from -20 to +125C.

Other common features include: a 0/4 to 20mA interface for transmitter; dynamic pressure measurement with 25 measurements per second; and a choice of nine selectable pressure units.

Up to 25,000 measured values can be recorded in the instrument.

Users can also select the measuring rate (0.04s to 24h) and the number of values to be measured.

Data can be evaluated using software or can be printed out on the Testo infra-red printer.

Each instrument is supplied with a TopSafe case for impact protection.
