Model 408 Series - Nitric Oxide Calibration Source

by 2B Technologies     based in Boulder, COLORADO (USA)

The Model 408 Nitric Oxide Calibration Source is a portable source of nitric oxide that allows one to calibrate any nitric oxide monitor.  The instrument scrubs NO from ambient air and produces either zero air or air having a mixing ratio of NO in the range 10-1,000 parts-per-billion by volume (ppbv).  The desired NO concentration is ...

Calibrated Orifices for Gas Flow

by Graftel Inc     based in Elk Grove Village, ILLINOIS (USA)

For use as flow rate standards or gas metering. Graftel, Inc. can provide a stainless steel orifice calibrated to flow at a specified rate for a specified inlet pressure for most gasses. All orifices are provided with NIST traceable calibrations performed by Graftel in compliance with ISO 17025-2005 certified by L.A.B. For nuclear power ...

Model 2021FG/FGS/FS - Fixed-Orifice Flowmeters

by ORANGE RESEARCH INC.     based in Milford, CONNECTICUT (USA)

Our flowmeters are designed for those applications where a rotameter is not appropriate. Consider the inherent problems of rotameters--they are difficult to read, especially with dirty or opaque fluids, have low pressure ratings and allow vertical orientation only. Orange Research low flow flowmeter models have large dials with bold markings and ...

Owlstone - Model OVG-4 - Calibration Gas Generator

by Owlstone Nanotech, Inc.     based in Norwalk, CONNECTICUT (USA)

The Owlstone Vapour Generator (OVG-4) is a compact, cost effective calibration gas system, which can generate NIST traceable, precise, repeatable and accurate concentrations of chemicals and calibration gas standards. Designed for calibration of industrial and scientific gas sensors, the OVG-4 incorporates permeation tube technology and can ...

Calibration Gas

by Foxcroft Equipment & Service Co. Inc.     based in Glenmoore, PENNSYLVANIA (USA)

These cost effective cylinders are filled with certified precision gas mixtures for calibration and response check “bump testing” of gas leak detectors or research instrumentation. “Home made” chlorine gas is uncontrollable as well as dangerous. The high concetration of chlorine in a 150 lb process cylinder is lethal to ...

Dynacalibrator - Model 120 - Calibration Gas Generators

by VICI Metronics     based in Poulsbo, WASHINGTON (USA)

Standard features on Model 120 include a glass or PTFE permeation chamber with screw cap access, solid state proportional temperature controller with digital readout of set point and chamber temperature, heater switch with LED indicator, flowmeter and flow control valve, span and overflow outlets, 12 VDC internal pump, activated charcoal scrubber, ...

Dynacalibrator - Model 500 - Calibration Gas Generators

by VICI Metronics     based in Poulsbo, WASHINGTON (USA)

This innovative design features two separate permeation chambers with independent temperature control systems. The chambers can be used independently, or together to combine concentrations of trace components. Separate solenoid valves allow the carrier flows to be switched from the dilution flow to a vent port.

Dynacalibrator - Model 230 - Calibration Gas Generators

by VICI Metronics     based in Poulsbo, WASHINGTON (USA)

With a flexible flow metering system to maintain a constant carrier flow through the permeation chamber, the Model 230 allows the dilution flow to be varied over a wide range, generating the spectrum of concentrations required for checking analyzer linearity. Like all Dynacalibrators, its large permeation chamber is big enough to accomodate ...

Dynacalibrator - Model 450 - Calibration Gas Generators

by VICI Metronics     based in Poulsbo, WASHINGTON (USA)

Ordinarily, the plumbing connections between the sample manifold, analyzer, and calibrator must be changed for each calibration. The Model 450’s unique “through-port” feature eliminates this chore. The mode control switch selects among standby, zero, span 1 (low concentration), span 2 (high concentration), and remote modes. In ...

Dynacalibrator - Model 340 - Calibration Gas Generators

by VICI Metronics     based in Poulsbo, WASHINGTON (USA)

The Model 340 adds a front panel mode control switch to select among zero, span, or remote calibration modes. In the zero mode, scrubbed air is delivered to the stream outlet. In the remote mode, the Model 340 can be externally programmed to deliver a zero and a span reference on command.
