testo 445 - Service instrument for air conditioning / ventilation systems

• Integrated differential pressure sensor with an accuracy of 0.2 % of f.v.
• Calculation of the flow velocity and the volume flow via Pitot tube (optional)
• Multi-point and timed mean calculation
• 2 probe inputs for additional pressure and temperature probes

 

• Speedy and accurate leak detection in natural gas pipes
• Audible and two-stage visual alarm
• Audible alarm if limit value is exceeded
• Optical alarm

 

• High-resolution colour display for the graphic representation of your measurement data
• Extended measurement menus - such as gas pipe testing - for a comprehensive analysis of your heating system
• Logger function for easy long-term recording of the measurement curve
• Graphic processing of measurement data

 

• Measures room temperature / humidity / alerts the occupants when thresholds are reached
• Large, easy to read display / shows current reading / provides at-a-glance 90-day statistic snapshot
• Long term stable sensor for long term / high quality readings
• Table and wall mount included

 

• Accurate measurement results, thanks to air density compensation via integrated absolute pressure measurement
• Measuring range: 0 to 10,000 ppm, 14 to 122 °F, and 5 to 95% RH
• The Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in your case - it transmits readings to the testo 440, from up to 65 feet away
• Practical button on the handle - for storing individual readings
• Versatile - the universal handle can be connected to all probe heads, so you can take care of more applications, and use less equipment

 

• Ideal for measuring the pH value of liquids
• The integrated temperature probe enables automatic temperature compensation
• Maintenance-free gel electrolyte
• Robust, waterproof and dishwasher-safe protective case (TopSafe, protection class IP68)

 

• Probes available as an option mean you can measure air humidity, temperature, absolute pressure, and dew point in compressed air
• Measures air moisture, material equilibrium moisture, pressure dew point
• Calculates dew point and dew point distance
• Cyclical printing of readings once a minute, for example

 

• APO (Auto Power Off) saves battery life
