NEW: OZONE MONITOR BMT 932 Firmware Version 2.00

July 2025

Firmware Version 2.00 for the OZONE MONITOR BMT 932 has been developed to meet the evolving demands of industrial applications while maintaining proven measurement accuracy and reliability. This upgrade introduces several enhancements to improve measurement efficiency and system flexibility including adjustable tube lengths for faster measurements or extended reach, a priority channel for time-critical monitoring in multi-channel applications, and support for future on-site firmware upgrades.

Individual Tube Lengths
The latest firmware introduces user-defined tube lengths so that the measurement system can be adapted precisely to the specific installation. The tube lengths can be configured either directly on the instrument or conveniently via the Windows software BMT Link 932.

Shorter tube lengths reduce sample gas transport time. This leads to faster response and noticeably shorter measurement cycle times, especially with the “Fast” setting. For applications demanding exceptionally stable readings, the “Low Noise” setting applies an extended averaging time to minimise signal noise. And, the “Standard” setting, as the factory default setting, maintains full backward compatibility, meaning no adjustments are needed for regular operation.

With support for tube lengths of up to 40 m, the BMT 932 can now connect to more distant sampling points, which is deal for large systems or complex installations. Regardless of tube length or setting, the firmware ensures precise compensation for sample gas transport time, even over long distances.

Tube Length Setting: Standard Setting: Fast Setting: Low Noise
2 m 20 s 5.7 s 10.3 s
5 m 20 s 8.0 s 12.5 s
10 m 20 s 11.7 s 16.3 s
20 m 20 s 19.2 s 23.8 s
40 m n/a 34.2 s 38.8 s

Priority Channel 1
The new priority channel feature allows the user to assign channel 1 to a specific sample point that requires a higher measurement frequency. This is particularly valuable in multi-channel applications such as for time-critical monitoring task or in high-importance area.

Firmware Upgrade
Firmware Version 2.00 implements field-installable upgrade capability. Consequently, future enhancements and customisable functions can be installed directly on site, thereby eliminating the need for return shipments. Please note that instruments with Firmware Version 1.xx must be converted at BMT.

From 7th July 2025, newly manufactured instruments will be supplied with Firmware Version 2.00. For further information, please contact your local BMT representative.
