[labnetwork] Honeywell MST Sensors

[Leif Steen Johansen]

Hello Hadi,

We have the exact same problem.
You could try to contact Sensorix in Germany who claims to have drop-in replacements for MST: https://www.sensorix.com/

A word of caution:

1)      We haven't tried these sensors ourselves, so we don't know how they work.

2)      If you use a third-party vendor, there is a potential risk that the gas detection system won't work properly.

Even though Honeywell recommends changing the MST gas sensors every 6 months, they might possibly function longer. According to a 6 year old data sheet for chlorine they guarantee < 10 % decay/6 months, but the sensor life time is specified to 3 years.

Best regards,
Leif

Dear Colleagues,

Another supply chain story here. Honeywell has informed us that the MST sensors that we had ordered in April 2021 and were supposed to be delivered earlier in March of this year won't be ready until early 2023. All our gas sensors (NH3, Cl2, SiH4, HCl) are due for replacement, and we are currently concerned about the risk of running possibly expired sensors. Anyone facing the same issue? Are there other reliable suppliers we can purchase these sensors from? Any advice is appreciated!

Hadi
