Forensics 4 Gas Data Logger Monitor — Built-in Pump, Graphing (O2, CO, H2S, LEL)

Forensics 4 Gas Data Logger Monitor — Transportable Job-Site Monitoring

The Forensics 4 gas data logger monitor is the larger, datalogging-focused transportable in the family — an area and transportable gas monitor you place at a worksite to monitor oxygen (O2), combustible gas (LEL), carbon monoxide (CO) and hydrogen sulfide (H2S) continuously with full computer datalogging for the record.

What the Forensics 4 Gas Data Logger detects (and what it doesn’t)

It monitors oxygen (O2), combustible gas (LEL), carbon monoxide (CO) and hydrogen sulfide (H2S) with a built-in pump and full computer datalogging — built for extended placed monitoring of a zone with detailed records. Like the rest of the family it is a single transportable unit, not a wireless-mesh networked area monitor; for a multi-zone perimeter (AreaRAE/Radius class) distributor sourcing is required. It does not read VOCs or specific toxics. For permanent coverage use a Fixed Gas Detection Systems system; for per-worker wear a Personal & Wearable Gas Detectors clip; for a lighter carried unit see Portable Gas Detectors.

Note on wireless area monitors: true wireless-mesh area monitors (the AreaRAE, Industrial Scientific Radius and RAE MeshGuard class) are sold through industrial distributors, not retail. The instruments here are transportable continuous monitors you place at the hazard for the length of a job — for a networked multi-zone perimeter, contact us about distributor-sourced wireless area monitors.

Forensics transportable continuous-monitoring family compared

• Choose the 4 Gas Data Logger for extended placed monitoring with full computer datalogging and a larger transportable body.
• For a lighter, lower-cost continuous monitor, the 4 Gas Pump Monitor covers most jobs.
• For pre-entry-focused use, the 4 Gas Monitor + Pump is the value pump option.

Frequently asked questions

Is the Forensics 4 gas data logger an area monitor?

It is a larger transportable continuous monitor for placed job-site monitoring — an area-monitoring use. It is not a wireless-mesh networked monitor; for that class see the distributor note in the Area & Transportable Gas Monitors hub.

What gases does it monitor?

It monitors oxygen (O2), combustible gas (LEL), carbon monoxide (CO) and hydrogen sulfide (H2S) with a built-in pump. It does not read VOCs, CO2 or specific toxics.

What datalogging does it offer?

Full computer datalogging plus a color display with live graphing, giving you detailed records of a job's exposure over time for compliance.

How is it different from the standard pump monitor?

It is a larger, higher-tier transportable unit focused on extended datalogging; the 4 Gas Pump Monitor is lighter and lower cost for most jobs.

Can it do pre-entry sampling?

Yes — the built-in sample-draw pump lets you test a space before entry as well as monitor continuously during the work.

Is it good for turnarounds and shutdowns?

Yes — its extended datalogging and transportable form suit long placed-monitoring tasks like turnarounds, with a record of the whole job.

Is it NIST calibrated?

Yes — USA NIST-traceable calibration; bump-test before use and recalibrate on schedule.

Can it monitor a whole perimeter alone?

One unit covers its zone. For a networked multi-zone perimeter use several units or a distributor-sourced wireless-mesh system; for permanent coverage a Fixed Gas Detection Systems system.

What alarms does it have?

Audible and visual alarms trigger when any of the four gases exceeds its set point.

What does it not detect?

VOCs, CO2 and specific toxics like chlorine or ammonia. For VOC monitoring use a PID; see the Gas Detectors hub.

Is it in stock and how does it ship?

Use the Amazon buy button for current availability and delivery timing through our fulfillment partner.

Does it require maintenance?

Yes — keep the pump and probe clean, replace electrochemical sensors periodically, and recalibrate on schedule to keep readings and logs accurate.
