Technical Specifications

Differential Pressure Measurement

The Testo 510 is designed to measure the difference between two pressure points.

This makes it useful for checking:

• Filter pressure drops

• Gas pressure

• Ventilation pressure

• Heating systems

• Air-conditioning systems

• Duct pressure

• Fan pressure

• Airflow systems

The instrument can display the measured pressure in different units, allowing technicians to select the unit most appropriate for their application.

Measuring Range

The Testo 510 has a differential-pressure measuring range of up to 100 hPa.

The high resolution of 0.01 hPa makes the instrument suitable for measuring relatively small pressure differences.

For very low pressure measurements, the instrument provides high sensitivity and is particularly useful for HVAC and ventilation applications.

Air Velocity Measurement

When combined with a suitable Pitot tube, the Testo 510 can also be used for calculating air velocity.

This allows the instrument to be used for additional HVAC applications such as:

• Air duct measurements

• Ventilation system inspection

• Airflow assessment

• Fan testing

• Duct pressure measurement

The instrument can compensate for air density, helping improve the usefulness of calculated air velocity measurements.

Temperature & Density Compensation

The Testo 510 supports temperature and density compensation for air velocity calculations.

This is useful when measurements are being performed under different environmental conditions.

Proper compensation helps technicians obtain more meaningful airflow measurements when working with HVAC and ventilation systems.

Pressure Units

The Testo 510 can display pressure measurements in multiple units, allowing it to be used across different technical applications.

Depending on the selected measurement mode, available units include:

• hPa

• mbar

• Pa

• kPa

• mmH₂O

• mmHg

• inH₂O

• inHg

This makes the instrument versatile for technicians working with different pressure specifications.

Hold & Min./Max. Functions

Hold Function

The Hold function allows the current pressure measurement to remain on the display, making it easier to record readings.

Min./Max. Function

The instrument can display minimum and maximum values measured during an inspection.

These functions are useful when pressure fluctuates during system operation.

Backlit Display

The Testo 510 features a backlit digital display, allowing measurements to be viewed more easily in poorly illuminated working environments.

This is especially useful when working inside equipment rooms, plant rooms, HVAC cabinets and other areas where lighting may be limited.

Magnetic Mounting

The instrument features integrated magnets that allow it to be mounted on suitable metallic surfaces.

This can be useful when technicians need both hands free while connecting pressure hoses or performing measurements.

HVAC Applications

The Testo 510 is particularly suitable for heating, ventilation and air-conditioning professionals.

Filter Pressure Drop

Measure the pressure difference across filters to determine whether a filter is becoming blocked or requires replacement.

Ventilation Systems

Check pressure conditions within ventilation and air-distribution systems.

Heating Systems

Measure gas pressure and pressure conditions in heating installations where the instrument is suitable for the required pressure range.

Air Conditioning

Perform differential pressure checks during HVAC installation, commissioning and maintenance.

Duct Measurements

Measure pressure differences within air ducts and use the instrument with a Pitot tube for air velocity calculations.

Typical Users

The Testo 510 is suitable for:

• HVAC technicians

• Heating engineers

• Ventilation technicians

• Air-conditioning technicians

• Building-services engineers

• Maintenance professionals

• Facility managers

• Industrial technicians

• Commissioning engineers

• Service technicians

Compact Pocket-Sized Design

The Testo 510 has a compact form factor of approximately 119 × 46 × 25 mm and weighs around 90 g.

Its small size allows technicians to carry it easily in a pocket, tool bag or equipment case.

The compact design is particularly useful for professionals who perform pressure measurements at multiple locations during routine service work.

Battery & Power

The Testo 510 operates using 2 × AAA batteries.

Battery life is approximately 50 hours, depending on operating conditions and use of the display backlight.

The automatic switch-off function helps conserve battery power when the instrument is not being used.

Protection

The Testo 510 has an IP40 protection rating.

It is intended for professional indoor and field applications but should be protected from water and excessive moisture.
