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.

The InstaCaliper is the U-shaped measuring head that attaches to 2nd Sight's TallyTrak nursery inventory app via an Android-based device. Use the InstaCaliper to measure plant diameters or circumferences without stooping or bending.

The InstaCaliper measuring head comes in three sizes - 50mm, 100mm or 150mm - giving you flexibility in nursery inventory management. Tag your data with any information you deem important.

Using the measuring head and the simple TallyTrak app, you can measure and count your tree inventory. Then, using our web portal, you can see your inventory in one glance. Data reports make our system compatible with eGrow, Growpoint, and SBI inventory systems.
