Traceable Dissolved Oxygen Pen

Tough ABS plastic housing and water-resistant design with o-ring seal and membrane keypad assure a long life in severe lab or harsh plant environments. HOLD button freezes the reading on the display. High contrast, easy to read 3/8-inch-high LCD digits simultaneously display oxygen concentration and temperature. At the press of a button, unit recalls minimum/maximum readings. Designed for intuitive, easy operation by everyone.

An individually-numbered Traceable® Certificate provided with each unit, assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA.  It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement.
