Myron L Company's new ULTRAPEN PT5 dissolved oxygen (DO) and temperature test pen is accurate, fast and simple to use. Advanced features include automatic correction for changes in membrane temperature; DO saturation adjustment for altitude and sample salinity; real time readings; and three calibration methods (air, water and 0-ppm DO). Its accuracy of ±0.01 ppm DO concentration and ±0.1% DO saturation, combined with its waterproof, rugged construction, make it ideal for any DO application.
