Wöhler CDL Series CO2 Monitor


The Wöhler CDL 210 CO2 data logger and the Wöhler CDL 110 CO2 data monitor are CO2 measuring devices (colloquially also called CO2 traffic light) for continuous monitoring of the carbon dioxide concentration (in ppm) and other air quality factors. Determination of the indoor air quality through combination of measurement and identification of:
  • The CO2-concentration
  • The air temperature
  • The air humidity
For CO2-monitoring of:
  • Housing spaces (comfortableness, humidity problems, etc.)
  • Conference rooms and lounges (e.g. schools)

Wöhler VIS 200 / 250 Service camera

Clear view, when space is tight.

Wöhler's innovative VIS 200/ 250 service camera enables you to easily analyze damage in pipes of 1 1/2" dia and larger – and no power outlet required. Compact by design and powered by a rechargeable battery, this complete camera set is supplied in a plastic case. The camera head features a powerful, integrated light to allow you to precisely analyze damage in waste water pipes (at least 1 1/2" dia) and inspect downpipes as well as flue gas lines. Absolutely essential to analyze damage quickly! Locate damage and inspect:
  • Waste water pipes of 1 1/2" dia and larger
  • Ventilation lines of 1 1/2" dia and larger
  • Inspect hollow spaces, e.g. in front-wall installations
  • Flue gas lines up to approx. 6" dia

Wöhler DP 700 Leakage Tester

Leakage test on ventilation systems and components

Ever-increasing demands are being placed on the energy efficiency of VAC systems. In that respect the leak-tightness of ductwork has a particularly important role to play. This aspect holds the greatest potential for saving energy, if it is possible to adapt the air flow to actual requirements in conjunction with low leakage rates. In this respect, low device-and ductwork leakages will in future need to be taken into consideration a great deal more. Consequently, corresponding measurements will gain in importance.
  • Leakage tests in large air leakage ranges: From individual components through to complete systems consisting of several 100 m²
  • Leakage tests on air-conditioning units, switchgear cabinets, climatic test cabinets, heat exchangers, cabinets for clean room technology and other housings
  • Leakage testing of rooms
  • On-site and laboratory measurements on structural components (e.g. OSB boards, windows)
  • Can be integrated into the final inspection routine of series production runs including optional program remote control, (controlled from a PC via USB port)
  • Suitable for tests of lower output performance (40 l/s), 110 V, 60 Hz

Wöhler IQ 300 CO2 Meter

The Wöhler IQ 300 CO2 meter is ideal for monitoring air quality in classrooms, waiting rooms, seminar rooms, etc.. It evaluates the air quality at any time based on measurement data. An important factor for monitoring indoor air quality is the CO2 content. Through breathing, people release moisture and CO2 into the indoor air and, if they are sick, also viruses. A high CO2 content in the air therefore indicates an urgent need for ventilation, because if this value is high, it can be assumed that the air is also polluted with other substances. Via a brightly traffic light LED as well as a clearly audible tone, the Wöhler IQ 300 warns when ventilation is required. The limit values for the warning functions are adjustable. If desired, users can also mute the warning tone, as the large display also shows clearly when the air quality becomes critical.
