We have DT85 and recently bought a DT80M.

Although, the instrument has not been installed and setup with the weather station bought separately since last 3 months.

Is datataker responsible for the application of the dataloggers or just the sale ?

Moreover, this is disheartening as we were promised end to end support.

What do the others do when the local vendors do not provide/ are unable to provide support ?

Hi chintap,

Can you send a formal complain email to our support email address (you may find that email address from our website)?
Depending on your application we may assist you with sensor connection.

Best regards,
Rudy Gunawan
