  testo 316-4, Ammonia (NH3) leak detector, including case, power supply unit, and headphones

  Extremely high sensitivity of 3g/a allows for the detection of even the most insignificant leaks.

  Visual and acoustic signaling for optimal leak detection.

  Constant sensor self-check guarantees that your work will be safe and fast.

  Headphone connection for reliable leak detection in noisy environments.

  Leaks in a cooling system have very serious consequences: the required cooling capacity is reduced, and in the worst case, the system may fail. This can harm the environment and lead to unnecessary costs for your client. Therefore, it is especially important for you to be able to quickly and reliably detect even the most insignificant leaks — for example, with the testo 316-4 leak detector.

  testo 315-3, Measuring instrument for carbon monoxide and carbon dioxide concentration

  Instrument for measuring CO and CO2 in ambient air, as well as relative humidity and air temperature.

  The testo 315-3 instrument is for measuring the concentration of carbon monoxide (CO) and carbon dioxide (CO2) in ambient air, as well as relative humidity and air temperature.

  During combustion processes, the composition of the ambient air continuously changes. Certain CO and CO2 concentrations pose a danger to humans. To monitor these parameters, measurements must be conducted in various areas.

  With the testo 315-3, specialists in the installation and service maintenance of heating systems can perform higher quality monitoring of gas heating equipment installed in residential buildings, office buildings, or industrial enterprises.

  The testo 315-3 is equipped with a high-precision electrochemical CO sensor and a load-resistant infrared CO2 sensor.

  Thanks to its robust design and the optional TopSafe protective case, the instrument is reliably protected against external influences. During measurements, the instrument will alert you to the exceedance of set limit values through optical and acoustic signals. Thanks to the IrDA or Bluetooth (optional) interfaces, you can transfer the obtained data to the testo 330 flue gas analyzer or print them out. This provides a good opportunity for documenting measurement results directly on site. The automatic shut-off function and the rechargeable lithium-polymer battery ensure long operating time and help avoid unnecessary energy consumption.

  Advantages of the instrument:

  • Simultaneous measurement of CO and CO
    2
    ​
  • Measurement of relative humidity and air temperature (optional)
  • Convenient and simple operation
  • Printing data directly on site using an optional printer
  • Data transfer capability to testo 330 (ver. 2010)
  • Display backlight
  • Audible and optical alarm upon exceeding limit values
  • Automatic shut-off function
    Compliance with standard EN 50543

  testo 316-EX, Electronic gas leak detector testo 316-EX

  Includes batteries, case, hex key, and factory calibration certificate

  Approved according to ATEX (94/9/EC)

  Flexible measuring sensor for hard-to-reach areas

  Can detect 3 different types of gas: methane, propane, and hydrogen

  The testo 316-EX gas leak detector helps you locate gas leaks, and thanks to its ATEX protection, it can even be used in potentially explosive areas. Gas detection and leak detection are possible on both indoor and outdoor gas pipelines and installations.

  When checking gas pipeline components for leaks or detecting a gas leak, a gas detection device with ATEX protection must be used. This is because, in a hazardous situation, it is essential to ensure that the gas measuring technology used does not trigger an explosion due to its own portable ignition sources.

  This ATEX protection is provided by the testo 316-EX gas leak detector (ATEX approval 94/9/EC). The multi-range gas detection device can identify methane, propane, and hydrogen. Gas concentrations are measured by a semiconductor sensor in the ppm range and displayed on the screen with a resolution of 1 ppm. Thanks to its flexible measuring sensor, gas leak detection can be performed even in hard-to-reach areas.
