Notes: We ran this chamber in a test of in both humidity and cooling. Cooling performed well after the R-404A compressor was replaced by a qualified technician.

Cooling performance was:
19C to -21C in 6 minutes,
to -30C in 9 minutes,
to -39C in 12 minutes,
to -55C in 20 minutes,
to -62C in 23 minutes,
to -66C in 32 minutes,
to -73C in 41 minutes.

The humidity tank and valve mounted by the steam boiler were functional; we adjusted the water level to keep the heater interlock closed. There is a tank and pump mounted to the chamber rear. It appears to be functioning correctly.

Humidity and de-humidify performance meet spec.

The chamber light works.
