The S4000 split type is a high-precision dew point hygrometer for laboratory use, with excellent accuracy, reliability, and long-term stability, used for humidity measurement and calibration. This product provides unparalleled accuracy and reliability in dew point measurement applications for air and gas systems in calibration laboratories. Its powerful three-stage Peltier semiconductor refrigeration module can achieve a temperature drop of over 70 ° C at room temperature. The S4000 split type includes an independent sensor and a 19 'x 3U display control unit. The power and signal lines are independent, making dew point control more stable and accurate. highlight Extremely sensitive dual light path High power heat exchange pump 4-wire 100 Ω Pt100 probe Dew point accuracy 0.1 ° C Swagelok®Or VCR connector Dual row multi unit LED display Current and voltage signal output and RS232 digital transmission
