testo 317-3 - CO measuring instrument for measurements in the environment
The testo 317-3 - CO measuring instrument for ambient measurements is a reliable tool for heating and ventilation professionals who carry out daily maintenance and installation work on gas boilers and heating systems. This instrument stands out from conventional carbon monoxide measuring instruments in particular due to its rapid operational readiness and flexible alarm function. Similar to the [testo 310 - flue gas measuring instrument], users benefit from proven measuring accuracy and a robust housing that has proven itself in tough everyday working conditions.
Reliable CO measurement in indoor air and more
In order to meet the requirements of heating and ventilation professionals, this compact device impresses with its rapid measurement readiness without a long warm-up phase. It measures the CO concentration in a matter of seconds and shows the determined values clearly on the display. Critical concentrations are indicated by an acoustic signal and a visual display. The individually adjustable alarm threshold allows precise adaptation to a wide range of applications.
An overview of the key technical data:
- Measuring range: 0 to +1999 ppm
- Accuracy: ±10 % (30 to 1999 ppm), ±3 ppm (0 to 29 ppm)
- Resolution: 1 ppm
- Operating temperature: -5 to +45 °C
- Battery type: 2 AAA microcells (typical runtime of 150 hours with beep deactivated)
- Storage temperature: -20 to +45 °C
- Ergonomic design with belt clip and wrist strap
The remaining features have been specifically designed to make working in demanding environments easier. These include above all the compact format and the freely selectable alarm limit value. In addition, a headset solution is included in the scope of delivery so that a warning is reliably perceived even in noisy environments. Thanks to the three-year guarantee on the CO sensor, the manufacturer underlines the longevity and high quality of the device.
Application examples from practice
- Maintenance of gas boilers: During the annual inspection, the CO values serve as an indicator of whether the system is working safely or whether measures need to be taken to optimize it.
- Servicing heating systems: Continuous CO monitoring is also required for larger systems in public buildings or commercial properties in order to minimize health risks.
- Inspection of ventilation and air conditioning systems (HVAC): Reliable detection of the lowest carbon monoxide concentrations is particularly important in sensitive areas such as hospitals or laboratories.
- Monitoring in closed rooms with combustion processes: Whether burner or combustion chamber - wherever carbon monoxide can be produced, the device performs precisely.
FAQs
How quickly does the device deliver measurement results?
As a rule, the device is ready for operation immediately after it is switched on; no lengthy zero phase is required. This makes it possible to determine very quickly whether there is a CO hazard.
Can the alarm be set individually?
Yes, the alarm threshold can be set according to requirements. This is particularly useful for different system conditions and local regulations.
What happens if an alarm could be overheard in a noisy environment?
In addition to the acoustic signal, the device also has a visual warning indicator. Headphones are also included so that the alarm can be heard clearly even in noisy environments.
How robust is the device in daily use?
Thanks to the enclosed carrying case with belt clip, the CO measuring device is protected against light impacts. A wrist strap is also included to prevent it from falling during measurement.
Does the device require regular calibration?
The device is supplied already calibrated. In order to maintain stable measurement accuracy in the long term, regular functional checks and, if necessary, recalibrations according to the manufacturer's specifications are recommended, depending on the area of application.
Conclusion
This reliable measuring instrument enables precise carbon monoxide monitoring in the room air and therefore serves as an important safety factor when handling heating and ventilation technology. Optimized measuring functions, a robust design and the flexibly adjustable alarm function make the daily work of professionals easier and ensure a high level of safety. A wide range of applications in residential and commercial properties, combined with a long battery life, make this device a strong partner in protecting against dangerous CO concentrations.
