        DTM precision digital thermometer is a single / dual-channel PRT / SPRT high-precision thermometer. The portable thermometer is light in weight and small in size. Its accuracy reaches ± 0.006 ℃ and can be traced back to national standards. The thermometer has built-in ITS-90 temperature scale formula, industrial platinum resistance, RTD polynomial, standard platinum resistance formula (Rtp, A4, B4, A8, B8 and other parameters), which is convenient for direct conversion to temperature for display without manual calculation. You can also directly display the resistance value.


        Data statistics and recording function

        ● The thermometer has two built-in sampling channels, the sampling speed is fast, and the sampling time is as short as 0.1S

        ● Both dual-channel simultaneous display and itinerant display

        ● Can display the operation results, such as: the difference between channels, the size value, etc .;

        ● One key to switch the display mode: resistance / temperature

        ● It can be connected to U disk, and the data can be stored in U disk in XLS form.

        Sensor management function

        ● Support up to 10 SPRT, 10 PT100 sensor parameter management.

        ● Import / export function of batch standard platinum resistance and industrial platinum resistance parameters.

        ● The sensor parameters can be quickly switched.

        ● Battery-powered for easy on-site use, optional software.

        ● Built-in rechargeable lithium battery, easy to carry to the site, 4 hours charging time, can be used for 120 hours.
