Measure dissolved oxygen pen reads to 100% air saturation in the palm of your hand.
Compact, rugged design 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.
Traceable to NIST To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Rugged ABS plastic case is 1-1/2 diameter x 8 inches; weight is 5 ounces. Supplied with a Traceable® Certificate, two spare probe heads with membranes, electrolyte solution, nylon carry case, and four AAA batteries.
