821S 10 Step Gas Divider

The Model 821S allows instrument operators and manufacturers to check the linearity and calibration of their instruments, by the use of only one calibration gas and one diluent.

821S 10 Step Gas Divider

Eleven fixed steps from 0-100% concentration are provided, each step rising nominally by 10%

The unit operates the method of dividing two gases through a chain of 10 capillary tubes, in such a way that the operator selects the number of capillaries to which each gas is open.

  • Extremely reliable repeatability performance of +/-0.5% of point
  • Remote control allowing automated instrument linearity auditing and calibration
  • UKAS and NIST calibration available
  • Remote control audit software available
  • Ideal for regulated gas analyzer auditing and calibration e.g. US EPA CFR40 Part 1065
