maPress Dual Sensor Differential Pressure Meter
Brand: madurmaPress - pressure meter equipped with two differential pressure sensors allowing to perform hi-resolution / hi-range measurements of pressure without switching range.
Besides pressure it allows to measure chimney draft, flow velocity, temperatures and relative humidity. Small size and reach offer of accessories makes maPress attractive pressure analyzer.
Features- Equipped with 2 differential pressure sensors:
- For low range, high resolution measurements
- For high range measurements
- Measurements of chimney draft and flow velocity (with help of Pitot tube)
- Works with an external portable printer via wireless communication (IR LED)
- Supply with four replaceable AA batteries (alkaline, Ni-Cd or Ni-MH) that provides up to 60 hours of work
- 150 mm fixed probe
- Optionally, 150 mm fixed probe with measurement of gas temperature
- Co-operation with digital RH and temperature sensors
- Results presented on LCD display (128 x 64) with back-lighting
- Built-in large memory for results saving
- Calculations of many additional parameters
