Temperature and Relative Humidity meter 
Q and A:
1) Our customer ask for Accuracy of 2% and your have quoted for 2.5%. Please confirm whether you can provide suitable model.
No,  Accuracy is Humidity 2.5% RH (@ 25 °C  / (77°F) , 30 ~ 95% RH)

2) Display of Air temperature relative humidity time and date simultaneously required
No, LCD display cannot have this function but you can see them from software.

3) Please confirm details of display provide by you.
LCD Display.  

4) Temperature required .ºC & .ºF, simultaneously or alternatively LCD DISPLAY size
It cannot  be displayed  simultaneously but you can choose one of it.

5) should operate on Supply Voltage: 230 VAC, ±5V,.50Hz, 1 Phase, AC supply.
You can purchase AC 230 V to DC 9V adopter at your country or from us.
(Optional adapter ADP-01 110V, ADP-02 220V)

6) Customer asks in DTM-320 manual, measurement range is 0%~100% but operating
environment is only 0 to 90% non-condensing –> so whether these two information
conflicts?


The sensor measurement range can work for 0~ 100% RH
but the operating environment  0 ~ 90% RH(Non Condensing) is for the meter itself.
There is no conflicts with each other.

Besides, 100% RH is close to water and this will cause meter damaged for
all electronics devices. Therefore, it is recommended to keep the sensor and meter dry to extend its reliability and usage life.
