Frequently Asked Questions

What is the difference between single gas monitor and multi-gas monitor?

A single‑gas monitor, like our Tango TX1, is designed to monitor one specific gas in the workplace. It’s best for workers who need reliable, always‑on protection from one critical gas.

A multi-gas monitor monitors multiple gases at the same time, commonly including:

  • Oxygen (O₂)

  • Combustible gases (LEL)

  • Toxic gases such as H₂S, CO, SO₂, or others based on risk

This kind of detector, like a Ventis MX4 or Ventis Pro5, is best for workplaces where gas risks are variable, simultaneous, or unpredictable.

How long do single gas monitors last?

The Tango TX1 has a lifespan of up to two years, with proper care and operating conditions.

What gases can a single‑gas monitor detect?

Single gas monitors can detect a wide range of gases, including Carbon Monoxide (CO),
Hydrogen Sulfide (H2S) Ammonia (NH3), and more. See the full list of sensor options here.
