Wöhler CDL 210 CO2 Data Logger

The Wöhler CDL 210 CO2 Data Logger is a CO2 monitor (also known as a CO2 traffic light) for continuous monitoring of carbon dioxide concentration (in ppm) and other indoor air quality factors.

CO2 monitor with temperature and humidity display
Large carbon dioxide (CO2) measuring range up to 9,999 ppm using true infrared CO2 measurement (NDIR)
Display of CO2 concentration, temperature, and humidity on the large display
Acoustic and visual alert when the preset carbon dioxide concentration is exceeded
CO2 data logger with adjustable log rates
Protection against data loss in case of power failure
Wöhler indoor climate software for reading and evaluating the measured data

The CO2 monitor is ideally suited for monitoring CO2 concentration in buildings. The CO2 content is crucial for determining indoor air quality and helps to optimize ventilation behavior. Air temperature and humidity are also displayed and support problem analysis (e.g., discomfort, humidity, mold, or concentration issues).

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

Easy to operate
high accuracy
Automatic or manual measurement sequence
Prints measurement reports on-site

Wöhler SC 660 Smart Connect

Drinking Water Tightness Check

The small and handy Wöhler SC 660 Smart Connect even manages pressure measurements up to 60 bar. This makes pressure tests on water pipes with water possible without any problems. The device can be connected to the Wöhler M 603 via Bluetooth, but can also be used independently for pressure and temperature measurements as it has its own display. Another option for using the Wöhler SC 660 is the Wöhler Smart Connect app. The user can download it free of charge to a mobile device and then control numerous measurements from there. Afterwards, the measurement data can be saved as a PDF protocol, sent or printed.

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.
