Light

The Testo 540 light meter is a quick and easy-to-use entry level model designed for measuring lighting conditions in the workplace. 

• Sensor designed based on the spectral sensitivity of the human eye 

• Quick readouts 

• Protective cap for safe storage 

• Compact and robust design 

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 

Air flow measurements in ducts, temperature measurements in laboratories, humidity measurements in production, pressure difference measurements in clean rooms. The Testo 480 climate measurement meter with a wide range of optional probes that allows you to measure, analyse and log these and a variety of other parameters with only one device. 

• Measure multiple parameters Temperature, Humidity, Pressure Turbulence, Heat radiation, Co2 Lux, PMV/PPD, WBGT 

• Professional software for reporting & data logging 

• Highly accurate digital probes 

• Intelligent calibration concept

Protect your sensitive and valuable exhibits and archived material with WiFi data logger testo 160 THL. The testo 160 THL climate logger with integrated temperature, humidity, lux and UV sensors ensures comprehensive monitoring of the ambient climate and light conditions in museums at all times.

• With integrated sensors for temperature and humidity, as well as lux and UV radiation

• Blends in perfectly with the surroundings thanks to an optional, customisable deco-cover

• Perfectly networked: data storage in the Testo Cloud, real-time alarm via email or (optionally in conjunction with an Advanced licence) SMS

• Simple to install, integrate and operate

Protect your valuable exhibits and archived material with WiFi data logger testo 160 E, which has connection options for 2 probes, ensuring comprehensive monitoring of the ambient climate and the light conditions in museums, storage depots and archives at all times.

• Connections for 2 probes – position the data logger discreetly in the base of a display cabinet and monitor the micro-climate in the cabinet with the connectable probes

• Blends in perfectly with the surroundings thanks to an optional, customisable deco-cover

• Perfectly networked: data storage in the Testo Cloud, real-time alarm via email or SMS (optional in conjunction with an Advanced licence)

• Simple to install, integrate and operate

Precise, reliable measurement of all air velocity and IAQ parameters with just one measuring instrument: the multifunction measuring instrument features intuitive operation with clearly structured measurement menus. Adjusting air conditioning and ventilation systems, monitoring air quality or carrying out comfort level measurements – thanks to versatile options for combining with high-quality, digital probes, you are ideally equipped to carry out your measuring task (please order probes separately).

• Intuitive: clearly structured measurement menus for volume flow, degree of turbulence, cooling/heating output, mould detection and long-term measurement, such as CO₂

• Wireless: Bluetooth® probes for extra convenience when measuring and less cable clutter in the measuring case (please order probes separately)

• Clear overview: large graphic display with parallel display of 3 readings

• Safe and reliable: internal data storage and USB port for data export

Adjusting air conditioning and ventilation systems, monitoring air quality or carrying out comfort level measurements – thanks to versatile options for combining with high-quality, digital probes, you are ideally equipped to carry out your measuring task (please order probes separately).

• Intuitive: clearly structured measurement menus for volume flow, K-factor, degree of turbulence, cooling/heating output, mould detection and long-term measurement, such as CO₂

• Wireless: Bluetooth® probes for extra convenience when measuring and less cable clutter in the measuring case (please order probes separately)

• Clear and reliable: large graphic display with parallel display of 3 readings as well as internal data storage and USB port for data export

• Includes a differential pressure sensor: for Pitot tube measurement and monitoring filters

Kit for measuring the illuminance in workplaces, for example in offices or in production areas. Keep the testo 440 air velocity and IAQ measuring instrument and a lux probe safely stowed away in the case. So you can get down to work straight away!

• Intuitive: clearly structured measurement menu for long-term measurement and determination of illuminance according to the V-lambda curve, thus for all common light/lux sources

• Precise: standard-compliant accuracy according to DIN EN 13032-1 and class C according to DIN 5032-7

• Convenient: non-slip probe contact surface for convenient positioning at the measuring location, internal data storage and USB port for data export

• Versatile: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes
