testo 445 - Service instrument for air conditioning / ventilation systems

• 30:1 optics for measuring temperature at a distance, even on small objects
• Fast measurement value recording at two measurements per second
• 2-point laser for spot sighting
• Display illumination

 

• Easy storage and evaluation of measurement data - internal memory for up to 7,500 measurement protocols, which can be read via USB port and further processed as a CSV file on the computer (e.g. with Excel)
• Practical rear magnets for secure attachment of the measuring instrument to metal surfaces (e.g. ducts)
• Automatic detection of probes, e.g. vane probe
• Large, backlit color display

 

• 32° wide angle lens with 7" minimum focal point
• Solar mode identifies solar intensity values
• SuperResolution technology enhances image quality to 640x480
• TwinPix overlays IR image over real image

 

• Automatic temperature monitoring in refrigerators: reliable and convenient
• Clever alarm system: warning by e-mail or SMS for critical temperature values
• Access to measuring value documentation possible at any time
• Advantage of the set: equipment ideally suited for refrigerator temperature monitoring and attractive price

 

• Ideal for measuring the pH value and temperature in semi-solid media, e.g. in meat
• Combined pH measuring tip with temperature probe - can be changed by the user
• Maintenance-free pH measurement thanks to gel electrolyte
• Two-line, illuminated display: pH value and temperature at a glance

 

• Display of gas concentration via bar display
• Self-test of sensor after switching on
• Pitch of alarm rises along with gas concentration
• Battery monitoring with optical display

• Infrared measurement with 1-point laser sighting and 6:1 optics ratio
• Display of differential temperature, such as between a window and air
• Hold function and min./max. values
• Display illumination

 

• Measures high-side or low-side refrigerant pressure (or both simultaneously, with 2 probes) in AC and refrigeration systems
• No hoses required; clean, simple, and accurate
• Low-loss refrigerant pressure testing!
• Use with the testo 115i pipe-clamp temperature probes for automatic superheat and subcooling calculations

 

• Reliable detection of escaping flue gases
• Flexible probe for inaccessible areas
• Acoustic and visual alarm

 

• High adjustment accuracy and stability thanks to dynamic setting dial
• High light intensity thanks to high-performance xenon flashlamp
• Powerful Li-Ion rechargeable battery pack for at least 2 hours of continuous operation
• Extremely short flash duration (< 9 µs)
