Feature 1Efficient Light Measurement: The mechanical illuminometer, based on mechanical and photoelectric technology, is specifically designed to measure illuminance. It accurately measures the light that falls on a surface providing robust and reliable results. 2Sensitive and Accurate: The device is constructed with a light sensitive component and a radiation measuring device. The light sensitive component can convert light into electrical signals. Meanwhile, the radiation measuring device restricts the acceptance of light within a specific angular range, ensuring a high degree of accuracy and reliability in the measurements. 3User Friendly Design: The use of the mechanical illuminometer is straightforward. Place the device at the required place and once the light sensitive component receives the light, it produces an electrical signal. The corresponding value of the illuminance is then displayed through a pointer, making the process simple and efficient. 4Durable and Portable: Created from quality plastic with a lanyard, the thermometer illuminometer is not only durable and reliable but also compact and portable. Thus, it can be conveniently carried and used as necessary. 5Wide Range of Application: The mechanical illuminometer can be used for greenhouses, lighting engineering, interior designs and construction projects to laboratory research. It can help assess the quality of light, optimize lighting plans, and enhance the comfort of the working environment. Item Type: Mechanical Thermometer Illuminometer Material: Plastic Weight: Approx. 54.00g/1.9oz Application: Greenhouse gardening, lighting engineering, interior design, construction engineering, laboratory research, etc. Package List 1 x Mechanical Thermometer Illuminometer
