InstaCaliper: Digital Caliper

Automated, Electronic Caliper for Nursery Inventory Management

Inventory has never been simpler -- ditch those old hand calipers!t a dateInventory has never been simpler – ditch those old hand calipers! The InstaCaliper electronic caliper is an easy-to-use tool for in-field inventory management. When the measuring head slides past a tree trunk, the InstaCaliper instantly calculates diameter or circumference using state-of-the-art sensor technology.

After sliding the InstaCaliper around a tree, 2nd Sight’s Ruggedized Handheld Computer (RHC) displays measurement information via the TallyTrak app. The RHC records each measurement with a date, time, and GPS location. You can tag the measurement with other information such as variety, field, row, and grade.

2nd Sight’s InstaCaliper system allows you to customize data collection. Define measurement ranges and link them to a color for easy identification and fewer counting errors. Record tree diameters, circumferences, or heights with the TallyTrak app. Count different plants of the same size quickly and easily. Reject multiple calipers to correct mistakes out in the field.

Using Wi-Fi, the RHC syncs field data to a secure 2nd Sight server. View data on a web portal and download data in CSV (comma separated values) format to import into Microsoft Excel and other software packages. Set a date range and other filters and run reports to show your inventory numbers.
