Multi-Function Controller

Last Upgraded 2002

The 4000 series multi-function controller features easy-to-use instructions, 16 key touchpad, and 2x16 character backlit LCD. Controller has a real-time clock and is able to control sample initiation based on a number of different criteria (e.g. interval time, pulse count, 4-20mA, external contact), and is programmable with a variety of different sample sequences (e.g. composite, consecutive, timed step). It also features an internal lithium battery to maintain program settings and information in the case of power failure.

Power Pack Upgrade Kit

Last Upgraded 2005

The 4000 series battery has gone through rigorous testing and improvements, particularly in regards to the cooling system. Whereas the previous system of cooling was convection, now the system includes both convection and forced air (fan), of particular importance in some sampling situations with high levels of waste heat. Also the body has been upgraded from plastic to metal, increasing reliability.

Stepper Assembly

Last Upgraded 2005

The stepper assembly unit is the arm which distributes samples used in discrete sampling. Recent changes and upgrades have helped prevent leaks, decrease on wear, and increase the life and performance of the unit. (Picture shown also includes stepper bracket.)
