Frequently Asked Questions

What gas does the PMD 2 detect?

The PMD 2 is designed specifically for detecting methane (CH₄), providing highly selective measurements with minimal risk of interference from other gases.

What makes TDLAS technology advantageous?

TDLAS technology measures methane using laser absorption, enabling precise methane-specific detection with virtually no cross-sensitivity to other hydrocarbons. This helps reduce false alarms and improve field productivity.

How long will the battery operate?

The rechargeable lithium-ion battery supports up to 12 hours of continuous use under normal operating conditions.

Can survey data be exported?

Yes. The instrument stores extensive survey data and supports wireless transfer via Bluetooth for reporting, mapping, and analysis.

Does the PMD 2 include GPS?

Yes. Built-in GPS captures location data for leak surveys and mapping applications.

Is calibration required?

Routine calibration is recommended to maintain accuracy. Automated and manual calibration options are available.

What accessories are available?

Probe options include telescopic survey probes, bar hole probes, flexible probes, bore probes, bell probes, and additional accessories designed for specialized leak detection applications.
