S4000 Remote Precision Dew-Point Hygrometer |
|
|
The S4000 Remote is a precision laboratory dew-point hygrometer with the ultimate accuracy, reliability and long-term performance for humidity measurement and calibration. The product offers unmatched accuracy and reliability in dew-point measurements of air and gas systems in calibration laboratories.
Its powerful three-stage Peltier thermoelectric heat pump gives a depression capability of more than 70°C at normal laboratory temperature. The S4000 Remote comprises a free-standing sensor and a 19" x 3U monitor unit, connected by individual power and signal cables for the most stable and precise dew-point control.
