Probe Options

Built-in Probe (DPM)

• Integral probe with Direct Contact Surface Temperature Sensor
• Measures dew point, relative humidity, air temperature and surface temperature

Built-in Probe w/Cabled Surface Temperature Sensor (DPMS)

• Includes built-in air temperature/humidity sensor and K-type connector

• Magnetic surface temperature sensor with armored cable and locking device to prevent accidental disconnection from the instrument during unattended operation.
