DP Measurements TT570 series | Micromanometer

Contact Instrument Solutions

The TT570 series of micromanometers comes in a range of different configurations including (0.1 Pa) and (1 Pa) resolutions as well as rechargeable and dry cell variants.

The TT570 series of hand held digital micromanometers are compact lightweight bi-directional units, with excellent stability and resolution. The very wide range of applications include:

• HVAC Commissioning and maintenance
• Aerodynamics and air flow research
• COSHH requirements relating to air flow and pressure
• Paint booth and clean room pressure differential measurement

Wide range of models available in metric and imperial measurement units with dry cell or rechargeable options.


Auto ranging      Automatically changes scale and resolution depending upon the pressure being applied. Ensuring accurate readings at all times. Maximum pressure range ± 7.5k Pa.

Over range      If the applied pressure is greater than the calibration limit. Display will indicate - - - - - - - -, to protect the instrument from being damaged.

Data logging      Up to 2500 readings can be stored either manually or automatically with date and time stamp. Data can be viewed on display with averaging function, which can be downloaded to a PC via the basic optional software.

Display       For easy viewing, the main digits are 10 mm high, unit of measurement, fast or slow mode, when the auto zero is in operation, number memory location used and with back light.

Audible feedback      Can be heard when a key is pressed thus giving that extra confidence.

Multiple ranges      Select the unit of measurement via the range key.

Auto switch off       For a longer battery life.

Auto zero       No need to disconnect the instrument from the pressure source to zero.


Pressure, velocity and accuracy       Please see manufacturers datasheet as this varies per model

Operational temperature        0 to 50 oC

Span stability versus temperature       0.1 % of range in use per oC

Zero drift       Negligible due to auto zero system, when auto zero set to 60 second intervals (2 minute warm up)

Zero system accuracy       ± 0.05 Pascal typical
