PosiTector DPM Dew Point Meter

1. Product description

The DeFelsko (USA) PosiTector DPM Dew Point Meter measures relative humidity, air temperature, surface temperature, dew point temperature and the difference between surface temperature and dew point, all at once. It is suited to checking compliance with the surface preparation requirements of ISO 8502-4.

2. Features

1. Versatile

① Universal gauge body accepts all PosiTector 6000, 200, SPG, DPM and UTG probes, easily converting from a coating thickness gauge to a surface profile gauge, dew point meter or ultrasonic thickness gauge

② Readings stored internally at the press of a button

③ Auto-log mode records readings automatically at user-set intervals, for unattended monitoring

④ Every stored reading is date- and time-stamped

⑤ Can be calibrated in the field

⑥ Switchable between °C and °F

⑦ Selectable operating language

⑧ High-contrast backlit display for bright or dim conditions

⑨ Display can be flipped for upside-down viewing

2. Simple

① Ready to measure – no calibration needed in most cases

② No need for complex tables or slide rules

③ Automatic alarm when weather conditions are unsuitable for painting

④ All readings are updated continuously and displayed together

⑤ Reset function quickly restores factory settings

3. Durable

① Solvent, acid, oil, water and dust resistant – weatherproof

② Sturdy, for outdoor and indoor use

③ Shock-absorbing rubber holster with belt clip

4. Accurate

① Responsive sensors give accurate, repeatable, reliable readings with long-term stability

② Trend arrows show whether readings are rising, falling or stable
