Integrated Height Measuring Device


An industrial innovation that is required by every total station, brought to you by HORIZON. Proudly Singaporean, proudly HORIZON.


Most surveying jobs started on the total station would require the user to input the instrument height as part of the pre-job requirement. Traditionally, this is accomplished via usage of a measuring tape, a leveling staff or some other measuring tool. The user would then note the height measurement, and input it manually in the instrument. The EZHeight™ system is designed to take care of this entire procedure in a simple step via an integrated device named the EZHeight™.




The EZHeight in use on the HORIZON H9 total station. It is the first height measurement integrated device of its kind to be fitted on total stations.




An invention and innovation by HORIZON managing director Mr H J Tang, the EZHeight™ is an integrated device built into the EDM of a total station. Using the laser emitted by the laser diode of the total station, it allows the beam to be centered to the plumb point directly below the instrument, and

the height of the instrument can be measured with a single push of a button and calculated via an onboard program. The height value is then automatically stored in the instrument and the user is ready to continue with the rest of the job process. The average time taken to accomplish this entire procedure

is about 4.5seconds.




The EZHeight™ device is currently available only for the HORIZON H9 series total station and for the

AGX series total stations as a standard feature. HORIZON owns an IP patent pending, #201106241-1,

for the EZHeight™ device. EZHeight is now available to HORIZON H9/HTS-580AGX total station users

as a standard integrated feature. EZHeight™ BENEFITS Using the EZHeight™ provides users with the following benefits:


a.) Height measurement accomplished in less than 1/3 of the time taken vs usage of measuring tape.

b.) Elimination of parallax and human errors using measuring tape.

c.) Self-contained height measurement system.

d.) Dispenses with measuring tape and other conventional height measure devices.

e.) Measures accurately to plumb point without hassle.

f.) Accuracy of 3mm.

g.) Automatic capturing and storage of measured height. No need for manual keying, and eliminates human error during this step.

h.) Increases pre-job efficiency when working with a total station.
