Gas Blender 100 Series Datasheet

Product catalog summary

Overview: The MCQ Gas Blender 100 Series is a compact, cost-effective solution for gas mixing and dilution, designed to replace traditional multi-channel systems with a single, portable unit. It supports up to three channels for non-aggressive gases, ideal for sensor or analyzer calibration.

Specifications: The device operates with a digital interface (RS485 and USB) and requires a power supply of 16-36 V DC. It can handle pressures up to 25 psi and operates within a temperature range of 0-50°C. The accuracy for each channel is 1% of the set point, with a repeatability of 0.16% of the reading value. The response time for changes in set point is 50 ms.

Design and Connectivity: The front panel includes quick connectors for input and output tubes, supporting 6 mm diameter tubes made from materials like Tygon, Viton, PTFE, Stainless Steel, or Polyurethane. The rear panel features a power switch, line power connection, USB, and RS485 connections, although the RS485 function is not currently active.

Functionality: The Gas Blender 100 Series simplifies gas delivery by integrating a control master and mass flow controllers into one unit. It uses air flow sensors and proportional valves to regulate mass flow, which can be set and monitored via PC software. The system supports up to 64 devices connected through RS485 for enhanced dilution capabilities, although this feature is not yet active.

Performance: The device supports mass flow rates from 0.01 sccm to 200 sccm, with an optional full scale of 500 sccm. It is compatible with all non-aggressive gases and provides output signals of 0-5 V, max 80 mA.
