CO (environment)

The Testo 435-2 multi function meter is designed to allow you to carry out multiple measurements that are necessary to check and adjust ventilation and air conditioning systems and assess the quality of the indoor air. 

• Measures Multiple Parameters
  C, RH, Co2, Co, Pressure, Draught,
  Air velocity, Volumetric Flow, Turbulance,
  U Value, Lux 

• Illuminated Display 

• Large Range of Probes 

• Large display 

testo 435-3 – multi-function climate measuring instrument with integrated differential pressure measurement. You can use this to carry out measurements which you need to adjust ventilation and air conditioning systems and assess room air quality. For this we offer a comprehensive range of optional probes and sensors to choose from.

• Includes differential pressure measurement for filter monitoring or for measurement with a Pitot tube

• Further optional probes can be attached: thermal and vane anemometers, along with probes for air humidity, CO₂, absolute pressure and temperature

• Display of dew point distance, min., max. and mean values

• Illuminated display

Carbon monoxide is a silent killer. The compact Testo 317-3 CO meter is designed to provide you with a quick and reliable means of testing ambient air for carbon monoxide. 

• Instant Start up: no zeroing phase 

• 3-year warranty on CO sensor 

• Alarm with adjustable thresholds 

• Carry case with belt clip and handstrap 

You can keep a close eye on indoor air quality with the testo 445 climate measuring instrument: the allrounder can measure up to 6 parameters (with the appropriate probe), which can help you make a professional assessment of indoor air quality. The climate measuring instrument therefore supports you in adjusting and checking ventilation and air conditioning systems.

• Multi-function climate measuring instrument: measure up to 6 measurement parameters at the same time

• Internal reading memory for up to 3,000 readings

• Automatic allocation of the duct cross-section to the measuring location (max. 99 measuring locations)

• Automatic mean value calculation and determination of the volume flow

The Testo 435-1 IAQ Kit is a multifunction instrument for measuring and assessing Indoor Air Quality and for adjusting and inspecting VAC systems.The Testo 435-1 is an affordable introduction to measurement engineering for ambient air conditions. Readings from up to 3 temperature probes can be displayed on the screen. Measurement data can also be printed on site with the Testo printer. 

• Measures Multiple Parameters
  Temperature, Humidity, CO2, Pressure 

• Illuminated Display 

• Large Range of Probes 

• Large display 

The high-quality testo 315-3 is an easy-to-use, ruggedly designed CO and CO₂ meter that enables you to carry out quick and reliable ambient measurements according to DIN EN 50543 standard.

• Measures CO & CO2 

• Temperature & Humidity Measurements 

• Optional Bluetooth Interface 

• Optical & Audible Alarms 

The ambient CO probe (in conjunction with the appropriate measuring instrument) helps you to detect carbon monoxide in indoor room air.

• Long-term measurement stability thanks to electrochemical sensor

• Automatic zeroing

• Measuring range: 0 to +500 ppm
