WatchGas SST1E 3 Year H2S Gas Detector (MINI) SST1E-H-36
Description
The
WatchGas SST1E 3 Year H2S Gas Detector (MINI) delivers three years of continuous hydrogen sulfide monitoring from a single activation — no calibration appointments, no battery swaps, no sensor replacements. Built on the SST1E MINI platform, it's the longest fixed-life option in the MINI H2S line.
The SST1E-H-36 carries the same IP67 ingress protection and 0–100 ppm detection range as the
SST1E-H-24, with the service life extended to 36 months. Audible, visual, and vibration alarms fire at 10 ppm and 15 ppm — below OSHA's 20 ppm H2S ceiling — giving workers time to exit before reaching the permissible exposure limit. The compact MINI form factor reduces clip bulk compared to the standard SST1 body; program managers who prefer the full-size equivalent can reference the
SST1-H-36.
Key specifications: Detection range 0–100 ppm H2S | Alarm setpoints 10 ppm / 15 ppm | Resolution 1 ppm | Service life 3 years from activation | IP67 rated | No charging required | Audible, visual, vibration alarm.
For teams that need sensor serviceability after three years — or whose program has bench infrastructure — the
SST1E-H serviceable variant is the MINI equivalent with a replaceable sensor. Call
1-800-467-4374 for fleet pricing on 3-year MINI programs.

Frequently Asked Questions
How long does the SST1E-H-36 last after activation?
The SST1E-H-36 is rated for 36 months (3 years) of continuous service from the date of activation. The device tracks its own remaining service life and alerts before end-of-life. At expiration, retire the unit and replace with a fresh SST1E-H-36 or transition to the serviceable
SST1E-H if your program adds service infrastructure.
What is OSHA's H2S permissible exposure limit and how does this detector help meet it?
OSHA's PEL for hydrogen sulfide is a 20 ppm ceiling — meaning worker exposure must not exceed 20 ppm at any time, not as an 8-hour average. The SST1E-H-36 sets audible, visual, and vibration alarms at 10 ppm and 15 ppm, well below that ceiling. This gives workers time to evacuate the area before exposure reaches the OSHA limit. Always pair continuous monitoring with a written confined-space entry procedure.
Is the SST1E-H-36 compatible with WatchGas docking stations?
Yes. The SST1E-H-36 is compatible with the
SST-DOCK touchscreen docking station for automated bump testing, data logging, and compliance record-keeping. Docking-station bump test records satisfy many site safety programs' documentation requirements for fixed-life monitors.
Should I choose the 2-year or 3-year MINI H2S variant?
The SST1E-H-36 reduces replacement frequency — three years versus two — which lowers program administration load for large fleet deployments. The per-unit cost is higher than the
SST1E-H-24, but total cost of ownership per year is often comparable or lower when you account for fewer replacement orders. Contact PK Safety at
1-800-467-4374 for a fleet cost comparison.
