1) Whether the price is inclusive of RS 232 CABLE and software for window.
DTM-321 price desn't not include optional accessory SE-310 software and cable.
2) Detail of software required.
Windows 98, NT, or upgraded.
3) 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)

4) 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.

5) Please confirm details of display provide by you.
LCD Display.  Please click image for large photo.

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

7) Memory back-up last hundred or more reading with date and time are required with battery back up.
Yes, there is memory back-up for data storage for DTM-322 dta logger.  Not for PC based DTM-321

8) 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)



9) Customer asks in DTM-321 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.
