A Simple Portable Reflectometer for Field Use
A small, portable, battery-powered field reflectometer, which utilized an integrating sphere, was developed for measuring reflectance from soils and intact leaves. Its light source was a flashlight bulb; its wavelength selection within the range of 0.4 P to 1.1 04 was achieved with interference filters. Comparison with laboratory instruments was favorable. Additional index words: reflectance, s...
متن کاملA Low Cost Field Usable Portable Digital Grain Moisture Meter with Direct Display of Moisture (%)
Moisture content of grain is one of the important parameters always considered when deciding the quality and price of grain, at the stage of harvesting, storage, processing and marketing. Grain having excess moisture content, if stored for long duration, will spoil due to insect/fungus infestation. Portable, field usable, and easy-to-use direct moisture (%) display Grain Moisture Meter is a nec...
متن کاملASVCP guidelines: quality assurance for portable blood glucose meter (glucometer) use in veterinary medicine.
Portable blood glucose meters (PBGM, glucometers) are a convenient, cost effective, and quick means to assess patient blood glucose concentration. The number of commercially available PBGM is constantly increasing, making it challenging to determine whether certain glucometers may have benefits over others for veterinary testing. The challenge in selection of an appropriate glucometer from a qu...
متن کاملDesign and evaluation of a novel portable erythema-melanin-meter.
BACKGROUND AND OBJECTIVES Objective evaluation of the pigmentation index (PI) and the eythema index (EI) of human skin is a prerequisite for successful optimization of laser- and intense-pulsed-light (IPL)-based treatment modalities in dermatology. STUDY DESIGN/MATERIALS AND METHODS We describe a three-wavelength technique for determining PI and EI as well as its particular implementation usi...
متن کاملDevelopment of a light-weight portable neutron survey meter.
A light-weight portable neutron survey meter was developed using a mixed organic gas counter for dose management at nuclear power plants and accelerator facilities. This survey meter, NSN31041, is ~2 kg in weight and W160×H250×L300 mm(3) in size, which is capable of measuring neutron ambient dose equivalent rate from thermal to 15 MeV neutrons. The neutron energy response of the survey meter is...
