Introduction

The SENSIT® GOLD 3 Multi‑Gas Leak Detector is an advanced instrument designed to support field teams when accuracy, speed, and reliability matter most. Built to enhance worker productivity and safety, it delivers advanced durability alongside responsive sensor technology that meets the proposed PHMSA 5ppm requirement. The industry‑leading data logging and mapping capabilities help teams document readings with confidence and work more efficiently in demanding real‑world conditions.

The SENSIT® GOLD 3 is well‑suited for applications such as odor response, gas leak investigations, pinpointing leaks on above ground equipment, barholing underground leaks, grading leaks and confined‑space monitoring.

Detect Multiple Gases Simultaneously

The SENSIT® GOLD 3 can detect and display up to five gases at the same time, including combustible gases, toxic gases, and oxygen. It provides clear, actionable readings for combustible gases, Oxygen (O₂), Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), and Hydrogen Cyanide (HCN) when configured to do so. This enables workers to quickly assess conditions during leak investigations and respond appropriately.

Readings can be displayed in % volume or parts per million (PPM), with optional LEL measurement for methane and propane, supporting a wide range of utility and confined‑space applications.

Standard Features Built For The Field

Designed for tough environments, the SENSIT® GOLD 3 includes:

|   Class 1 Division 1 intrinsically safe design for use in hazardous areas where combustible gas is present

|   Rugged, IP64-rated housing for protection against dust/water and dependable performance in the field

|   Two-speed internal pump for fast sampling and improved response time

|   Audible tick, adjusted by a thumbwheel, to help pinpoint leaks quickly

|   Integrated flashlight for low-light conditions

|   Optional GPS module to record co-ordinates and time-stamp leak investigations

Together, these features deliver a dependable, easy‑to‑use instrument that supports field crews across a variety of operating conditions.

Technology That Keeps Teams Productive

The SENSIT® GOLD 3 is equipped with long‑life Oxygen sensors, a bright and easy‑to‑read display, multi‑language support, an LED warning light, and Bluetooth® connectivity. These capabilities help reduce downtime and simplify day‑to‑day operations; so crews can stay focused on the task at hand.

The instrument is compatible with:

|   SMART‑CAL 360 for automatic calibration and bump testing

|   SMART‑LINK 360 for downloading and managing data logs

|   SERVICE 360 for firmware updates

This connected ecosystem helps organizations maintain compliance, document work, and keep instruments ready for use.

Certifications

The SENSIT® GOLD 3 is UL‑certified for use in Class 1 Division 1 hazardous locations. Combined with SENSIT’s decades of experience in gas detection, this certification reinforces the GOLD 3 as a trusted, reliable solution for organizations that require confidence in their gas detection instruments.
