Selected product option for Digital temperature and humidity probe for handheld meters. All information below applies to the selected product option.
Field humidity checks become easier when the probe is ready to use, easy to exchange and precise enough for demanding handheld measurements. DX 310 measures relative humidity and temperature for PRO D01 and PRO D05 meters, while also supplying calculated values such as dew point, wet bulb temperature, absolute humidity and frost point temperature.
Reliable results are supported by multipoint factory calibration for relative humidity, with calibration data stored directly in the probe. That means probes can be interchanged without recalibration, helping service teams work faster with less setup effort. Accuracy reaches ±1.2% RH from 0…85% at T=0…50 °C, while the Pt100 temperature sensor covers -40…+125 °C with 0.01 °C resolution.
The compact Ø14 mm stem, 4-pin M12 connector and low power consumption of <1 mA typ. make the probe well suited to portable measurement tasks. It can be screwed directly onto the meter for one-handed operation or connected by cable when the measuring point is harder to reach.
The probes connect to compatible PRO handheld meters via the DX-Sensor-Interface and a 4-pole M12 connection.
Relative humidity is measured with a temperature-compensated capacitive sensor, while temperature is measured with a Pt100 element.
The probe provides multiple calculated climate values, including dew point, wet bulb temperature, absolute humidity, mixing ratio and frost point temperature.
DX310 can be screwed directly onto the instrument or connected by cable. DX311 uses an ergonomic handle with cable connection.
DX311 is available with 1 m, 2 m or 5 m cable lengths, with other lengths on request according to the ordering structure.
Optional filter caps include sintered stainless steel, PTFE and standard PBT versions with stainless steel grid protection.
