A low cost, computerized gas dilution system with an advanced Windows user interface, the 4040 now supports up to eight mass flow controllers, allowing a broader range of dilutions (up to 10,000:1).
The Environics® Series 4040 is a computerized gas dilution system that automatically generates precise gas standards for rapid multi-point calibration of analyzers.
The gas mixes can be used in generating precise gas calibration standards, creating gaseous atmospheres or producing gas mixes for analytical research or production purposes. The Series 4040 can produce gas concentrations from percent to ppb levels for single or multi-point calibration, allowing you to use fewer cylinders.
The system consists of two components: the Series 4040 instrument and the user's personal computer. The user interface is a Microsoft® Windows application that communicates with the Environics system via a USB (standard) or RS232 serial interface.
Bluetooth enabled devices running Windows software can also control the unit remotely (optional).
Additional options include the ability to remote start, remote stop, and canister filling stop all via a dry contact closure. Optional alarms available and can include visual alarms upon low input cylinder pressure.
Units can now be ordered or retrofit to run on a 24V power source so you can use your unit anywhere.
The Series 4040 consists of a single chassis now supporting up to eight mass flow controllers. The mass flow controllers are factory calibrated using a primary flow standard traceable to the United State's National Institute of Standards and Technology (NIST). Each flow controller utilizes an 11 point calibration table with linear interpolation, to increase accuracy and reduce flow controller nonlinearity.
The humidification option allows specific Relative Humidity (RH) levels to be added to the output gas of the system. RH levels between 0 - 95% can be achieved. The humidifier is factory calibrated for a specific RH level to an accuracy of 5% (assuming a constant flow rate and gas temperature), and is NIST traceable.
The humidification option is rear panel mounted and consists of a humidifier and a 250mL gravity feed D.I. water reservoir. The humidifier is made from a water vapor permeable tube made of Nafion (a Teflon derivative). The humidification option incorporates a continuous purge path to prevent moisture build-up and condensation.
