Survey meters in use in an extreme environment "hotspot" detector on long pole being used for detecting gamma Meters can be fully integrated with probe and processing electronics in one housing to allow single-handed use, or have separate detector probe and electronics housings, joined by a signal cable.
An example of the CD V-715 survey meter. By far the most common US civil defense meter on the market today. This is a simple ion chamber radiological survey meter, specifically designed for high-radiation fields for which Geiger counters will give incorrect readings (see above). Survey meters do not read alpha or beta radiation.
A typical total station can measure distances up to 1,500 meters (4,900 ft) with an accuracy of about 1.5 millimeters (0.059 in) ± 2 parts per million. [ 4 ] Reflectorless total stations can measure distances to any object that is reasonably light in color, up to a few hundred meters .
The Geodimeter (acronym of geodetic distance meter) was the first optical electronic distance meter surveying instrument. [ 1 ] [ 2 ] It was originally developed for measuring the speed of light . [ 3 ] [ 4 ] It was invented in 1947 by Erik Osten Bergstrand [ sv ] and commercialized in 1953 by the AGA ( Aktiebolaget Gasaccumulator ) company of ...
NMC was founded in the early 1950s. Their analog products included Geiger counters, gamma and neutron detectors, survey meters, and soil analyzers. Some are now considered museum pieces.
Hand-held ion chamber survey meter in use. Portable instruments are hand-held or transportable. The hand-held instrument is generally used as a survey meter to check an object or person in detail, or assess an area where no installed instrumentation exists. They can also be used for personnel exit monitoring or personnel contamination checks in ...
Single axis meters are cheaper than tri-axis meters, but take longer to complete a survey because the meter only measures one dimension of the field. Single axis instruments have to be tilted and turned on all three axes to obtain a full measurement. A tri-axis meter measures all three axes simultaneously, but these models tend to be more ...
Meter data management (MDM) refers to software that performs long-term data storage and management for the vast quantities of data delivered by smart metering systems. This data consists primarily of usage data and events that are imported from the head-end servers managing the data collection in advanced metering infrastructure (AMI) or automatic meter reading (AMR) systems.
