PosiTector DPM

Is the PosiTector $\text{DPM}$ calibrated at the factory?

Yes. Every $\text{PosiTector}$ $\text{DPM}$ arrives fully calibrated and ready to measure. It includes a Long-Form Certificate of Calibration traceable to $\text{NIST}$ or $\text{PTB}$, which documents the actual readings taken by the instrument during its calibration.

Does the PosiTector $\text{DPM}$ provide a wet-bulb temperature measurement?

Yes. When the $\text{DPM}$ is combined with either a $\text{PosiTector}$ Advanced gage body or the $\text{PosiTector}$ SmartLink wireless probe adapter, it will display and record the calculated wet-bulb temperature measurement.

Are the Relative Humidity ($\text{RH}$) and $\text{Air}$ $\text{Temperature}$ ($\text{Ta}$) sensors field-replaceable?

Yes. Field-replaceable, pre-calibrated sensors are compatible with $\text{PosiTector}$ $\text{DPM}$ integral probe models ($\text{DPM1}$ and $\text{DPM3}$). This allows users to quickly change the sensor on-site without the downtime associated with returning the entire instrument for service.

Is the $\text{PosiTector}$ $\text{DPM}$ suitable for high pressure environments?

The standard model is not, but the $\text{PosiTector}$ $\text{DPMD}$ probe model is specifically designed for use in pressurized environments (up to $\text{100}$ $\text{psi}$ / $\text{0.69}$ $\text{MPa}$) and features a $\text{1/2}$” $\text{NPT}$ $\text{threads}$ for secure installation on pipes and tanks.

What is the “Clean $\text{RH}$ $\text{Sensor}$ mode” feature?

The “Clean $\text{RH}$ $\text{Sensor}$ mode” is a maintenance feature that helps to restore sensor performance after the $\text{DPM}$ has been exposed for prolonged periods to environments with high humidity or high concentrations of Volatile Organic Compounds ($\text{VOCs}$).
