Industrial Scientific Ventis MX4 Standard 4-Gas Monitor – Non-Pumped with Slim Extended Li-ion Battery

Industrial Scientific Ventis MX4 Standard 4-Gas Monitor – Non-Pumped with Slim Extended Li-ion Battery

The Industrial Scientific Ventis MX4 Standard 4-Gas Monitor is a compact, portable gas detection instrument designed to provide continuous monitoring of four common atmospheric hazards: combustible gases, oxygen, carbon monoxide, and hydrogen sulfide.

This non-pumped Ventis MX4 configuration comes equipped with four installed sensors, including an LEL sensor calibrated to pentane, an oxygen (O2) sensor, a carbon monoxide (CO) sensor, and a hydrogen sulfide (H2S) sensor. It also includes a rechargeable slim extended lithium-ion battery and desktop charger.

Designed for personal gas monitoring, industrial safety, and hazardous work environments, the Ventis MX4 combines four-gas detection capabilities with a compact design that is comfortable to wear throughout the workday.

The non-pumped diffusion configuration continuously monitors the atmosphere surrounding the worker without requiring an internal sampling pump. Audible, visual, and vibrating alarms alert users when gas concentrations reach configured alarm thresholds.

Four-Gas Detection Capabilities

The standard Ventis MX4 configuration includes the following sensors: 

1. Combustible Gases (LEL) - The catalytic combustible gas sensor monitors lower explosive limit (LEL) concentrations. This model is configured for pentane calibration.

2. Oxygen (O2) - The oxygen sensor monitors atmospheric oxygen concentrations to help identify oxygen-deficient or oxygen-enriched environments.

3. Carbon Monoxide (CO) - The carbon monoxide sensor detects this toxic, colorless, and odorless gas, which can be produced by combustion engines, heating equipment, and industrial processes.

4. Hydrogen Sulfide (H2S) - The hydrogen sulfide sensor detects this toxic gas commonly associated with wastewater treatment, petroleum refining, oil and gas operations, and other industrial applications.

Slim Extended Lithium-Ion Battery

This Ventis MX4 configuration includes a rechargeable slim extended lithium-ion battery designed to support extended personal monitoring applications. 

The slim extended battery provides approximately 18 hours of typical operating time under specified conditions. Actual battery life depends on operating conditions, instrument configuration, sensor selection, alarm activity, and battery condition. 

A desktop charger is included for convenient battery recharging between shifts. 

Non-Pumped Diffusion Operation 

This Ventis MX4 is supplied in a non-pumped configuration. It detects gases through diffusion, meaning the surrounding atmosphere enters the sensor openings naturally without an internal sampling pump. 

For applications requiring remote atmospheric sampling before entering a confined space, a compatible Ventis Slide-on Pump may be available separately. Confirm accessory compatibility and the appropriate monitor configuration before ordering.

Frequently Asked Questions – Industrial Scientific Ventis MX4

1. What gases does the Industrial Scientific Ventis MX4 monitor detect?

The standard four-gas Ventis MX4 configuration monitors:

• Combustible gases (LEL)

• Oxygen (O2)

• Carbon monoxide (CO)

• Hydrogen sulfide (H2S)

This particular model has all four sensors installed and uses a pentane-calibrated LEL sensor.

2. Is this Industrial Scientific Ventis MX4 model pumped or non-pumped?

This model is a non-pumped diffusion gas monitor. It detects gases entering the instrument through natural air movement rather than using an internal sampling pump.

3. What is the difference between a pumped and non-pumped Ventis MX4?

A non-pumped Ventis MX4 is designed primarily for personal atmospheric monitoring. A pumped version uses an internal pump to draw air samples through tubing, making it suitable for remote sampling applications.

A compatible Ventis Slide-on Pump is also available for certain configurations, allowing users to convert a compatible diffusion monitor for remote sampling.

4. How long does the Ventis MX4 slim extended lithium-ion battery last?

The slim extended lithium-ion battery provides approximately 18 hours of typical operating time under specified conditions. Actual runtime depends on temperature, instrument configuration, sensor operation, alarm activity, and battery condition.

5. Does the Ventis MX4 include a battery charger?

Yes. This product configuration includes a desktop charger for recharging the rechargeable slim extended lithium-ion battery.

6. What does pentane calibration mean on the Ventis MX4?

Pentane calibration means the combustible gas sensor is calibrated using pentane as its reference calibration gas. The monitor's LEL readings are based on this calibration configuration. Response to other combustible gases may differ, so appropriate correction factors and manufacturer guidance should be followed.

7. Can the Ventis MX4 detect oxygen deficiency?

Yes. The installed oxygen sensor continuously measures atmospheric oxygen concentration and can alert users when oxygen levels reach configured low or high alarm thresholds.

8. Does the Ventis MX4 detect carbon monoxide and hydrogen sulfide?

Yes. This standard four-gas configuration includes dedicated CO and H2S sensors to monitor these two toxic gases.

9. Can the Ventis MX4 be used for confined space entry?

Yes. The non-pumped version can be worn for personal atmospheric monitoring during confined space operations. However, remote pre-entry atmospheric sampling requires a compatible pumped configuration or an appropriate pump accessory.

Always follow applicable confined space entry procedures and OSHA requirements.

10. What is the warranty on the Industrial Scientific Ventis MX4?

Industrial Scientific specifies a four-year warranty for the monitor and standard CO, H2S, O2, and LEL sensors. Batteries and certain other components have separate warranty coverage.

11. Can the Ventis MX4 be calibrated?

Yes. The Ventis MX4 is a serviceable, calibratable gas monitor. Calibration should be performed using the appropriate Industrial Scientific calibration equipment, compatible gases, and manufacturer-recommended procedures.

A bump test should also be performed according to the manufacturer's instructions and your company's gas detection safety procedures.

12. Is the Ventis MX4 compatible with Industrial Scientific docking stations?

Yes. The Ventis MX4 is compatible with supported Industrial Scientific docking and instrument management systems, including applicable DSX docking station configurations and iNet services. Confirm compatibility with the specific docking station and software version.
