H2S Gas Monitors

Reliable Features for Hydrogen Sulfide Detection and Protection

Our hydrogen sulfide detectors deliver precise monitoring with electrochemical sensors that trigger multiple alarms when gas levels exceed safe thresholds. Each single gas detector features audible alarms, vibration alarms, and visual warnings to ensure workers are alerted even in noisy industrial environments.

Built for durability, these hydrogen sulfide detectors withstand harsh conditions while maintaining accuracy across the full detection range from low concentrations to high-concentration emergency alerts.

Advanced Technology & User-Friendly Design

Modern hydrogen sulfide detectors incorporate cutting-edge electrochemical gas sensors with extended service life and reliable performance. You may choose between alert only or User-friendly LCD displays that provide real-time readings in ppm, while intuitive controls make bump testing and calibration straightforward for maintenance personnel. 

Lightweight, compact designs ensure comfortable wear in the breathing zone without interfering with daily work activities, while ATEX certification guarantees safe operation in explosive atmospheres.

Frequently Asked Questions

What H2S concentration levels trigger alarms on these monitors?

Many monitors set low alarms at 10 ppm and high alarms at 15 ppm levels, ensuring early warning protection. Custom alarm settings are available from PK Safety.

How often should I perform bump tests on H2S gas detectors?

Daily bump tests are recommended to verify that sensor and alarm functions work correctly by exposing the instrument to a known hydrogen sulfide gas concentration.

Why is hydrogen sulfide particularly dangerous?

This colorless gas is heavier than air and settles in low-lying areas, creating concentrated pockets that can cause rapid unconsciousness without proper ventilation.

What should workers do if their H2S monitor alarms?

Immediately evacuate to fresh air, alert others in the area, and do not re-enter until the atmosphere has been properly ventilated and is safe. 

What are the early symptoms of hydrogen sulfide exposure?

Early symptoms include headaches, dizziness, nausea, and eye or respiratory irritation. At higher levels, this toxic gas causes loss of smell, confusion, and breathing difficulty.

What is the difference between a disposable and a serviceable H2S monitor?

At PK Safety, we offer both disposable and serviceable H2S monitors to meet diverse needs and budgets. A **disposable H2S monitor** is a sealed unit designed for a specific lifespan, typically two to three years, after which the entire device is replaced. These monitors are generally lower in upfront cost, require minimal maintenance (beyond daily bump testing), and are ideal for short-term projects, contractors, or situations where maintenance resources are limited.

In contrast, a **serviceable H2S monitor** is designed for long-term use. While it has a higher initial cost, its sensors, batteries, and other components can be replaced or serviced. This allows for a longer overall lifespan for the device, often resulting in a lower total cost of ownership over many years. Serviceable monitors require periodic calibration and sensor replacement, making them suitable for ongoing operations where regular maintenance is feasible and desired.

What is the typical lifespan of an H2S sensor, and can it be replaced?

The typical lifespan of an electrochemical H2S sensor, which is commonly used in our monitors, is generally between two to three years. However, this can vary based on the manufacturer, environmental conditions (such as extreme temperatures or humidity), and the frequency and concentration of gas exposure. Prolonged exposure to high concentrations of H2S can shorten a sensor's life.

For **serviceable H2S monitors**, yes, the H2S sensor can be replaced. This is a key advantage of serviceable units, as it allows you to extend the life of your monitor without needing to purchase an entirely new device. For **disposable H2S monitors**, the sensor is integrated into a sealed unit and cannot be replaced; the entire monitor is discarded once its operational life expires or the sensor fails. We offer a range of replacement sensors for our serviceable models to help you maintain your equipment effectively.
