Bios Defender 510 and Defender 520 are true primary flow meters and are immune to flow source pulsation without the need for in-line dampers. The Defender Series is more accurate and more repeatable than the predecessors, the DryCal DC-Lite and the DryCal DC-2. Flow units may be set to ml, l, cc, or cf. The Defenders can be set to take individual readings, continuous hands-free readings, or set to read in user selectable time intervals. The Defenders can also be set to include up to one hundred readings in a group average. Each Defender is shipped with the basic Optimizer 110 datalogging software which allows for automatic recording and graphing of flow measurements. The Optimizer 120 software is available as a factory option or may be added later as a field upgrade, and allows the user to not only capture, but secure, organize, search and present data. |

DryCal DC-Lite® Air Flow Calibrator Employs
"frictionless" dry piston technology in rugged, pocket-book sized Air
Flow
Calibrator that is NIST traceable, true primary standard, even under
field
conditions. The Bios DryCal DC-lite has five flow ranges of 10 to 500
ml/min,
50 ml/min to 2 L/min, 100 ml/min to 7 L/min, 20 ml/min to 20 L/min, 500
ml/min to 30 L/min. |

DryCal NEXUS® STP Correction, Data Storage and PC
Communication
Link The NEXUS is used with a DryCal-Lite for datalogging of
calibration
flow data, date and time stamping, employee ID, pump and sample ID, and
optionally correction of flow rates to Standard Temperature and
Pressure
conditions for mass flow calculations. Nexus provides critical "chain
of
custody" continuity. Logged information transmitted to PC via RS232
(serial)
link. |

BIOS
DryCal DC-2® Air Flow Calibrator The DC-2
employs Bios' well known "frictionless" dry-piston technology in a
rugged
instrument that automatically corrects flow rates to Standard
Temperature
and Pressure Conditions (STP) suitable for field calibration of air
sampling
and mass flow monitoring instruments. Data can be logged using a PC via
serial cable (RS232) or hard copy obtained from a printer (parallel
port). |
