How to Order

Optec can assist with advice and equipment for the installation of a NGN monitioring site. However, our involvement is limited and on-site participation is not possible. If your require on-site assistance or a complete turn-key installation including our products, towers, data loggers, solar power, heated lab sheds, etc., we at Optec recommend Air Resource Specialist, Inc.

Of course, the technical manual and papers in the Publication pages need to be read and understood. The NGN-2a and -3a requires much advanced preparation if the installation is going to be successful. Call Optec and we will review your application and requirements.
The standard package from Optec usually consists of the instrument (#88100 NGN-2a or #88125 NGN-3a) and a power supply (#86905 for outdoor use or #88905 for indoor).
A short lab cable assembly is included with the standard package so that the instrument can be operated on the bench and the instrument variables setup.
Connector parts are include for the user to construct a power and data cable for the main installation. Optec can construct this cable for a slight charge if requested. Refer to to #88901 for the cost per foot of cable.
A span gas apparatus is need for calibration. Parts are included in the standard package for use with the customer's own span gas device. These parts include: hepa filter, orfice and brass hose fitting. Consider the Optec Span Gas apparatus (#88915) if you wish not to construct your own. For multiple instrument purchases, only one apparaturs is required. The 1 lb SUVA 134a gas cylinder is not avaialable from Optec since shipping compressed gas is usually not allowed. This product is available from most automotive supply stores for only a few dollars per can. Do not purchase the product with leak seal additive.
The standard package includes the PC windows control and data logging software. Updates are free from our web site. Locate the Software Download link on the NGN pages.
Other items to consider are: extra lamps (#88610), replacement filters for the clean air canister (#88605) and an extra clean air canister ( (#88600) so that filter media changes do not have to be done in the field.
