Yes, a $40,000 temperature and humidity chamber would be nice. However, the MHM-A1 has a slightly different physical design than the MHM units that came after it. MHM-A1 is 52" tall, too big for the AES chamber. NIST does use chambers for their masers. However, my understanding is that they were chambers designed for hospital applications. I was told they were cheaper. Regards, Skip Withrow

Hi Indeed my “guess” at the cost could easily be off by 5X. Some of these custom / short run “appliances” can be insane price wise.
