Description
Description
The MH-1200H-S-H2S is the diffusion hydrogen-sulfide model with separate 0-50, 0-100 and 0-200 ppm configurations. It is a single-gas choice for a named H2S measurement requirement. If other channels are required, compare a model that lists those gases explicitly.
Choose the Configuration for Your Measurement
- Gas and options: Hydrogen sulfide, with three current range/SKU pairs.
- Sampling: Diffusion sampling is stated in the product description.
- Selection boundary: A single H2S instrument does not acquire O2, CO or combustible-gas channels from the application name.
Order Options
| Select an option | SKU |
|---|---|
| 0-50 ppm | GAS-H7Q2-01 |
| 0-100 ppm | GAS-H7Q2-02 |
| 0-200 ppm | GAS-H7Q2-03 |

Product Details and Specifications
The MH-1200H-S-H2S is a portable hydrogen sulfide detector for H2S checks during facility and field inspections. An electrochemical sensor measures gas in the air around the instrument through diffusion sampling. The detector has a rear clip and protective cover for carrying during a measurement round. Select the required H2S range when ordering; each range is a separate product variant.
H2S Range Options
Choose from 0-50 ppm, 0-100 ppm, or 0-200 ppm according to the concentration span required for your work. The three ranges are separate order configurations. The standard configuration samples by diffusion. An external sampling pump is an optional setup for applications that need a different sampling arrangement; confirm the pump setup before ordering.
Readings, Alarms, and Records
The monochrome dot-matrix LCD shows the gas reading and concentration unit. The display supports ppm and mg/m³ units, and its backlight can be set to switch on automatically during an alarm. Audible, visual, and vibration alarms give three ways to notice an alert. Alarm points can be configured, and up to 100 alarm records can be reviewed on the detector. Zero and self-calibration functions are available on the instrument.

Before Use
With diffusion sampling, the surrounding air must reach the detector's sensor openings. Follow the supplied instructions and your site's procedures for calibration, alarm settings, and gas-monitoring checks. Product photos show the shared housing; the demonstration screen labels may differ from the ordered H2S configuration.

Questions Before Ordering
Should I select H2S-only or multi-gas?
Write down all required gas channels for the task. Select this product for its H2S configuration; compare an explicitly multi-gas model when more channels are required.
Are the three ranges measured simultaneously?
They are separate variants with separate SKUs. The current selector does not establish a three-range instrument.
