        Introduction

        DTWH-B handheld multi-channel temperature calibrator adopts precision platinum thermal resistance (IPRT, Pt100) or standard platinum resistance (SPRT, Pt25) sensors for accurate temperature measurement, with extremely high stability and resolution; the instrument uses two sections No. 7 (AAA) battery-powered, low power consumption, long standby time; simple instrument operation interface, quick and convenient application.

        Function

        1. Dual channel, resistance type, precision temperature difference measurement

        2. Convenient test for constant temperature bath, directly read fluctuation and temperature difference

        3. The hardware circuit seeks temperature difference, resolution and stability far exceed software calculation

        4. No sensor calibration is required to measure the temperature difference and fluctuation of the constant temperature bath

        5. Low power consumption, using two AAA alkaline batteries

        6. Temperature measurement can be calibrated as a whole

        7. The temperature unit can be switched: Celsius (° C), Fahrenheit (° F), Kelvin (K)

        8. The instrument body is small and exquisite (excluding sensors)

        9. Automatic complete shutdown function, delay can be set

        10. The display adapts to sunlight and dark places
