Introduction

The SENSIT® Trak‑It® 4 marks the next generation of advanced gas leak survey and documentation technology. Designed to support utility and compliance teams in the field, the Trak‑It 4 combines powerful data logging, GPS mapping, and a range of sensor configurations into an intuitive platform built for speed, accuracy, and confidence. By streamlining how leak data is captured, mapped, and reported, Trak‑It 4 helps organizations work more efficiently while maintaining strict documentation standards.

The Trak‑It 4 is a versatile Multi-Gas Detector and documentation solution for professionals responsible for maintaining gas system safety and compliance. It is well‑suited for applications such as below ground gas leak detection, above‑ground gas leak investigations, compliance‑driven system inspections, leak documentation and grading, and ongoing system monitoring programs.

Purpose‑Built For Modern Leak Surveying

The SENSIT® Trak‑It® 4 is designed to collect, record, and map gas leak data in real time. The system captures precise location and survey information, allowing crews to clearly document findings during routine leak investigations and compliance‑driven work.

By automatically associating readings with GPS coordinates, Trak‑It 4 reduces manual entry, minimizes errors, and creates a clear digital record that supports confident decision‑making in the field.

Clear Data, Reliable Documentation

Trak‑It 4 delivers consistent, reliable documentation by logging results alongside time and location data. This structured approach helps utilities standardize reporting and simplifies post‑leak detection review and analysis.

Data can be collected and displayed in clear, easy‑to‑interpret formats, supporting effective leak classification, prioritization, and follow‑up while reducing administrative burden on field crews.

Standard Features Built For The Field

Designed for daily use in demanding environments, the SENSIT® Trak‑It® 4 includes:

|   Rugged construction designed for utility work

|   User‑friendly interface for efficient field operation

|   Integrated GPS for accurate survey mapping
