Rated 1 out of 5 by from Does NOT project a ring of laser dots This device does not have the key feature that is so clearly shown in the illustration. It does NOT project a ring of laser dots. It has the usual, useless and misleading SINGLE dot. I returned the device. If you need the laser dot ring feature, this unit is not for you.

Can the 1mv/degree analog output be read from the terminals on the thermometer unit itself? or is the RF transmitter base required? Specifically, I'm asking about the four contacts near the bottom of the device

Asked by: Tim from Facture
Thank you for your interest in our product The output jack of the transmitter base provides a 1 MVdc per degree analog output. A mini plug cable connected to a banana plug pairs is supplied with the OS-DT8855W . Please reference the manual per the attached link which has additional details

Can this be used with custom software for the wireless function or will it only work with the OS-DT8855W software? I currently use the OS-MINIUSB-SN201 with modbus rtu and would like to have the wireless feature of the OS-DT8855W to transmit information

Asked by: DevinH
