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.
