Testing Pen Measures Temperature & Dissolved Oxygen

Nov. 8, 2018

The UltraPen PT5 dissolved oxygen (DO) and temperature test pen is designed to be accurate, fast and simple to use in diverse water quality applications. Features include:

  • Proprietary sensor design;
  • Stable microprocessor-based circuitry;
  • Adjustments for altitude and sample salinity for DO concentration;
  • Temperature compensation algorithm that dynamically corrects for changes in membrane temperature during measurements;
  • Real-time readings; 
  • Easy-to-read LCD;
  • One-handed operation; and
  • Three calibration methods: Zero (0 ppm DO), Air (water-saturated air) and Water (air-saturated water). 

When fully calibrated, the pen is accurate to ±2% for DO saturation. DO membranes are contained in easy-to-install screw-on caps. The pen’s waterproof, rugged aircraft aluminum construction, plus its ability to accurately measure DO saturation and concentration, make it suitable for both laboratory and field applications.
