testo 770-1 - Hook clamp meter

• 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

 

• 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

 

• Measures moisture in wood / building materials
• Non-destructive / precise measurements up to 2?in.
• 10 characteristic curves for different types of building material / wood
• Backlit display / hold function / min/max memory / ergonomic design

 

• With dew point calculation and max/min display
• Humidity sensor is not affected by condensation
• Large, clear display
• Durable quality: capacitive humidity sensor with long term stability for many years of measurement

 

• 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

 

• Two sensitivity levels, with audible and visual indication
• Flashing LED indicates sensitivity range, down to 12 V AC, or standard range above 50 V AC
• Differentiates hot from neutral in AC outlets
• Low pass filter reduces false indications

 

• Plug-in temperature and humidity probes
• Large, easy to read display

• Measures air temperature / RH
• Calculates dew point / wet bulb temperature
• Displays min/max values, hold function, power off mode
• Integrated long-life humidity sensor for long lasting quality

 

• Even more accurate measurements thanks to the new processor
• Improved control of limit values due to min./max. function
• Combined instrument with infrared and penetration measurement
• Optical and audible alarm

 

• Tightness testing and load testing on gas pipes
• Serviceability testing with air by pressure drop on gas pipes
• Pressure testing on drinking water and waste water pipes using air
• Automatic recording of measuring values over several hours
