[labnetwork] FW: Gas Monitor

[Robert M. Hamilton]

At UC Bekeley we have had experience with Zellweger 
tape-based systems. We chose their system because a 
tape-based system does not require the same level of annual 
service to verify and calibrate each individual gas detector 
as chemical sensors.

Having said this, we did not choose Zellweger for our new 
NanoLab. I found them slow in their response, expensive and 
not willing to support legacy systems. I believe Honeywell 
acquired or reps. Zellweger but have not had recent 
interactions with them.
