Manufacturer: Testo
£719.00 (ex VAT)

Highly accurate with internal differential pressure sensor, ideal for inspecting extraction units and ventilators and for monitoring pressure drops in filters. The instrument also has two probe sockets to connect external temperature probes or pressure probes, for example, for simultaneous monitoring of condensation and evaporation pressure.

  • Temp. compensated differential pressure sensor 0 to 100 mbar integrated in instrument
  • 2 probe sockets for pressure and temperature
  • Long-term analysis with internal data memory
  • Printout on-site
  • Save data according to site and analyse on PC/notebook
  • Direct calculation of velocity speed and volume flow
  • Multi-point and timed mean calculation
  • Density compensation
  • 1 analog signal can be evaluated per interface
  • Scaling of analog signal in hand-held instrument
  • Transmitter can be supplied with power from testo 521, for example
  • 4 to 20 mA interface can be connected to testo 521, 526, 400, 650 und 950 hand-held instruments
  • Two user-defined probe inputs allow the connection of external probes for pressure, temperature, current/voltage
