The PT5 is designed with high-performance features including: proprietary sensor design; industry leading accuracy; readings in concentration, % saturation, or both; altitude & salinity adjustments; 3 calibration methods – air, water, & 0 ppm DO; dynamic membrane temperature correction; user-selectable LIVE and HOLD modes; IP67 dust-tight & waterproof up to 1 meter / NEMA6 submersible enclosure.

PT5 Measurement Modes include: Hold mode, which continuously displays real-time readings until stable or for 3 minutes, whichever comes first, then displays final reading, and LIVE mode, which continuously displays real-time readings for up to 5 minutes.

PT5 Parameter Modes include: DO Default, which alternates between displaying the DO concentration in ppm, the DO saturation in %, and Temperature; DO Concentration, which alternates between displaying DO concentration in ppm and Temperature; and DO Saturation, which alternates between displaying DO saturation in % and Temperature.
