Description:

The AP-T312 is an easy-to use, robust and high precision two channel digital temperature transmitter. The AP-T311 is functionally similar to AP-T312 with the exception of having only a single sensing element.

The AP-T300 series uses the RS232 port for connection to a personal computer (PC).

They can also be connected to the USB port via a USB-RS232 adapter. (The adapter is not provided and should be purchased separately).

The sensing elements of AP-T300 family are connected with
1 ft. (30 Cm) of flexible cable.

The AP-T312 having two independent sensing elements permits differential temperature measurement between two user defined points. This feature is useful in measuring temperature gradient in an area or in a gas flow stream.

The combination of AP-T300 family with associated Windows ® based software provides you a powerful temperature logger.

The software allows you to select the sampling rate from a predefined range. In addition, it has the feature of automatic reduction in sampling rate when the input temperature change is less than a user defined value.

The software automatically saves the data in ASCII text format compatible to Excel ® for future analysis.

The AP-T311 and AP-T312 can provide a measurement resolution better than 0.04 F (0.02 C).

Each unit is individually calibrated and delivered with 2-point calibration data.

AP-T300 family is robust and water proof.
