100% HR measurement

100% HR measurement

100% HR measurement

(OP)
Maybe it is not the correct place to post.
I have a closed test chamber.  700 mm W 530 mm H 630 mm
deep

I need it to be 100% HR at 41 °C +/- 0.3 °C

No incoming or out coming air .

The chamber is loaded once  with material to test for up to 72 hours, open the  door is avoided.

It have a internal blower , air is routed to perforated pipes submerged in water where the shielded resistance heat the water, so the air bubbles in the water.

A PID controller , work ok for the temperature show from 40.9 to 41.1 °C.

My query .

How I can measure the 100% HR.

Small opening can be made to locate sensor.

I also think to make a secondary small circuit by a small blower to route air from the chamber , trough the sensors and route inside the chamber.

Any help will be granted.
Thanks in advance.


  

  






   
 
 

RE: 100% HR measurement

Given that most RH sensors are rated non-condensing, you might want to just use a wet bulb thermometer and read the RH from the Psych chart.
