Area measuring instrument / hand-held area measuring instrument Model: HT4-YMJ-1 library number: M282444 


 Host Profile: TMJ area measuring instrument series for farmland, green space, forests, waters, beaches and other outdoor area of ??the accurate measurement of irregular, can be connected to a computer for data export and analysis. 
 Basic configuration: standard configuration 
 Area measuring instrument (measuring instrument acres), also known as: GPS hand-held size device area detector instrument measuring acres of farmland area measuring instrument measuring instrument agricultural operations 

 Area measuring instrument type list: 

 Model 


 HT4-TMJ-I type 



 HT4-TMJ-II type 




 Function 



 Difference 


 General type, automatically or manually directly measure the area, latitude and longitude, distance, perimeter and other indicators, price setting and price computing function, a data storage and query functions, stored directly on the host. 


 Mapping type, except with all the features of type I, the increase of large-capacity EEPROM memory, RS232C communication interface, measurement data can be imported into the computer shows the measured contour plots of land, the software has a graphical memory, graphics, copy, graphics correction, area calculations and other functions (software gift). 







 Area measuring instrument features: 

 1, for a variety of shapes farmland, green space, forests, waters, beaches and other outdoor regular and irregular area of ??precision measurement. Acres and square meters can be displayed simultaneously, and directly set the price and the price of computing power, but also to adapt to China's national conditions. 

 2, real-time display latitude and longitude accurate positioning, but also measure the distance, perimeter, the full realization of a multi-purpose instrument, more suitable for agriculture and forestry. 

 3, HT4-TMJ-II-type area measuring instrument addition to HT4-TMJ-I type all the features, but also equipped with large capacity EEPORM memory Measurement data can be imported into the computer shows the measured contour plots of land, the software has graphics memory, graphics, copy, graphics, correction, area calculation. 

 Area measuring instrument used functions: 

 Area of ??automatic measurement: hand-held meter bypass measurement area a week, the instrument automatically records the coordinates of the route and calculate the area surrounded by an area in square meters and acres units displayed simultaneously. 

 Manual measurement area: the area or for more regular traffic inconvenience of area (on the way there are buildings, bridges, trees and other obstacles can not be adopted) can be used to manually measure the area, the only way to measure the number of vertices of the data, not detour along the four weeks required by law. 

 Area average: Automatic calculation of multiple measurements of the average data, the actual measurement generally require two measurements to improve measurement accuracy. 

 Latitude and longitude measurements: real-time display through satellite positioning of longitude and latitude location, easy to pinpoint. 

 Distance measurement: by measuring the coordinates of two points, quickly calculate the distance between two points, in meters display. 

 Data to fill: area measurement, if the end point and starting point for no overlap, the instrument automatically fill the data of these two lines, and calculate the area. 

 Visible satellites: the number of visible satellites, real-time display apparatus, the more the number of satellites in the higher measurement accuracy, to help surveyors determine the accuracy of the measurement results. 

 Area measuring technical indicators: 
 Area measurement range :1-60000 acres; if in square meters as a unit, then the measurement range :500-99999999m2 
 Area measurement accuracy :1-10 acres of ± 2.5%; 10 acres of ± 1% above 

 Latitude and longitude position accuracy: 2.5 meters (CEP) 

 Distance Measuring range :0-999,999.9 m 

 Distance measurement accuracy: 2.5 meters (CEP) 

 (Note: 1 acre = 666 square meters
