Hi,
I recently purchased a AIPO Dry Cabinet AP-48EX (48L) online from Tago Tech website.
As stated in the manual, i set the digital meter to 45%RH.
To ascertain the %RH is at 45% inside the cabinet, i placed a digital temperature/hygrometer inside to compare the reading.
The temperature reading is consistent at 29degC with a deviation of +/- 0.2 degC, which is rather acceptable to me.
However, the %RH deviation was +10% higher, which seems not normal to me.
Reading on the dry cabinet digital meter was reading at 45%, but the hygrometer inside the dry cabinet was reading 56%, which is 10% higher. Even if i set it to 40%RH, the hygrometer inside will always give me a +10% higher reading than the digital meter.
Because my hygrometer inside the cabinet is not calibrated, i do not know which if the dry cabinet digital meter is working fine or properly calibrated.
But i do believe that my hygrometer is working fine, because if left at room temperature environment, the same hygometer would read 80%RH(+/-5%), which is typical of Singapore climate condition.
If i turn on air-conditioning in the room, the %RH would drop to 60% (+/-5%).
Can anyone advise if the digital meter of my dry cabinet is working fine?
Do i need to send in for a calibration?
