CALIBRATION GAS DIVIDER
MODEL 821S 10-Step Gas Divider
The Model 821S allows instrument operators and manufacturers to check the linearity of their instruments, by the use of only one calibration gas and one diluent. Eleven fixed steps from 0-100% concentration are provided, each step rising by 10% The unit operates the method of dividing two gases through a chain of 10 identical capillary tubes, in such a way that the operator selects the number of capillaries to which each gas is open. The Model 821S has a repeatability performance of +/-0.5% of point.
   


Discontinued - CALIBRATION GAS PRE-DILUTER
Discontinued - MODEL 852V5SP for 2 Gas Inlets
Discontinued - MODEL 853V5SP for 3 Gas Inlets
These Models can be used either to dilute 2 or 3 gases or to increase the versatility or the Model 821S Gas Divider. When using the Pre-Diluter, the calibration gas to be diluted, and the diluent gas are connected to the rear of the unit, at a pressure of 50psi. A 20- turn counting dial and a flow meter on the front panel, allow the percentage dilution to be set. Each unit is supplied with its own logarithmic calibration curve for the purpose of correctly setting the dilution. The units are temperature controlled to 40 deg C, and can be supplied with remote controlled servo kit and D to A converter.
   


NH3 AND NOX CONVERTERS FOR GAS ANALYZERS
MODEL 410 (NH3)
MODEL 420 (NOx) CONVERTERS
This compact 3U high 19” rack enclosure houses both the NH3 to NO converter as well as a self contained heated filter and calibration gas selection valve. It is generally used with Chemiluminescent NOx analyzers such as Signal’s Model 4000VM.
   


NOX CONVERTER TESTER
NOxGen Model 3A
NOxGen Model 3R
The NOxGen Series 3 allows instrument operators and manufacturers to check the converter efficiency of their Chemiluminescent NOx analyzers. The unit is controlled by using two decade thumbwheel switches adjustable from 00 to 99, and a three position ozone level switch for low, medium and high settings. The NOxGen 3R provides the option of remote control using TTL levels for all operational functions.
   


ZERO AIR SUPPLY
MODEL AS80
The Model AS80 catalytic air purifier is designed to provide an inexpensive source of clean, zero-grade air for flame ionization detectors (FID). The unit removes all hydrocarbons, including methane, down to 0.1% of original level. Up to 10 FID units can be run from one unit. The AS80 contains a high temperature furnace containing alumina pellets coated in platinum. this oxidizes all combustible compounds to CO2 and H2O. The unit can completely remove methane at rates of up to 5 l/min high efficiency and up to 20 l/min medium efficiency.
