WatchGas SST1E Serviceable H2S Gas Detector (MINI) SST1E-H
Description
The
WatchGas SST1E Serviceable H2S Gas Detector (MINI) packs full SST1 serviceability into a noticeably smaller body — purpose-built for confined-space and personal monitor programs where clip weight and profile matter. A field-replaceable electrochemical H2S sensor, IP67 ingress protection, and a three-year instrument warranty give service teams the same long-run economics as the full-size
SST1-H, in a lighter package workers actually keep clipped on.
The SST1E-H measures hydrogen sulfide from 0–100 ppm with audible, visual, and vibration alarms at OSHA's 20 ppm ceiling. It charges wirelessly via WatchGas induction cradles, pairs with the
SST-DOCK touchscreen docking station for automated bump testing and data logging, and runs on the same calibration caps and accessories as the rest of the SST1 line. Factory-trained technicians in-house perform sensor swaps and full recertification — turn it around without sourcing a third-party service center.
Key specifications: Detection range 0–100 ppm H2S | Alarm setpoints 10 ppm / 15 ppm (adjustable) | Resolution 1 ppm | IP67 rated | Wireless induction charging | Three-year instrument warranty | ATEX / IECEx certified.
If your program includes workers who prefer or require the standard SST1 form factor, the
SST1-H runs the same sensor family. For teams that want zero maintenance commitment, the
SST1E-H-24 and
SST1E-H-36 are the fixed-life MINI equivalents. Call
1-800-467-4374 to configure a MINI fleet for your site.

Frequently Asked Questions
What is the difference between the SST1E-H and the SST1-H?
The SST1E-H is the MINI-form-factor variant: physically smaller and lighter than the standard SST1-H. Both carry the same IP67 rating, the same field-replaceable electrochemical H2S sensor, and the same three-year instrument warranty. Detection range, alarm setpoints, and docking-station compatibility are identical. Choose the SST1E-H when monitor profile and clip weight are a priority; choose the SST1-H when workers prefer the standard form factor or need the slightly larger display.
What are the H2S alarm thresholds on the SST1E-H?
Default alarm setpoints are 10 ppm (low) and 15 ppm (high). OSHA's permissible exposure limit for H2S is a 20 ppm ceiling — exposure must not exceed that level at any time, not just as an 8-hour average. The SST1E-H alarms well below that ceiling, giving workers time to exit the area before reaching the OSHA limit. Setpoints are adjustable for site-specific confined-space permit requirements.
Can the SST1E-H sensor be replaced in the field?
Yes. The SST1E-H uses the same serviceable electrochemical sensor design as the full SST1 line. Factory-trained technicians in-house can perform sensor replacements and full recertification. The replacement H2S sensor is the
SST-SPARE-H. Contact PK Safety's service team at
1-800-467-4374.
Does the SST1E-H work with the WatchGas docking station?
Yes. The SST1E-H is fully compatible with the
SST-DOCK touchscreen docking station, which automates bump testing, calibration, and data logging across the SST1 and SST1E lines. Multiple docking stations can be networked for fleet-wide compliance reporting.
