Manual - MC1 and Automatic - AC1, AC4, AC8 Calibration Units

Yokogawa's Zirconia oxygen detector systems offer a variety of calibration units for quick, easy control of calibration gases giving the user simple, accurate calibration. Users with single-point measuring systems, such as the model ZR402 converter, may choose either manual or automatic calibration units, models MC1 or AC1, respectively. For users with multi-point measuring systems, such as the model AV550 converter, the user has a choice of either a 4- or 8-channel auto calibration unit, models AC4 or AC8, respectively.

  • Dry instrument air as span gas and reference air
  • Single point of control for reference air and calibration gases
  • Easy wiring of converter to solenoids
  • Easy tubing from multiple detectors to a single calibration system
  • Easy setting of flow rates to all detectors

M1233SR Portable Calibration Kit

This portable calibration kit is designed for applications where there is no permanently mounted calibration solution and can be used with any ZR probe. It consists of two 103 L calibration gas bottles (1% O2, balance N2 for zero and 21% O2, balance N2 for span), two 0.5 L/min flow regulators, ten feet of tygon tubing, and one 1/4" NPT to 1/8" barb fitting, all contained in a hard carrying case with a shoulder strap.

MC1 Manual Calibration Panel

The MC1 can be used to calibrate the sensor and monitor reference air delivery for any ZR probe. The panel allows easy operator adjustment of calibration and reference gas flow rates, as well as manual switching between zero and span calibration gases. The panel requires standard clean, dry, instrument air for reference air and span calibration gas, and also requires zero calibration gas. 

AC1 Automatic Calibration Unit

This automatic calibration unit can be used to calibrate the sensor and monitor reference air delivery for any ZR probe attached to the ZR402G analyzer. Calibration is simplified by allowing the whole calibration procedure to be done from the analyzer's interface (or remotely) in semi-automatic mode, or by setting a timed automatic calibration in the ZR402G. The solenoid valves also have manual overrides for troubleshooting or performing a manual calibration if desired. The unit requires standard clean, dry, instrument air for reference air and span calibration gas, and also requires zero calibration gas. 

IAC-24 Compact Automatic Calibration Unit

This automatic calibration unit is directly mounted to the ZR22G probe's reference and calibration ports. Calibration is simplified by allowing the whole calibration procedure to be done from the analyzer's interface (or remotely) in semi-automatic mode, or by setting a timed automatic calibration in the ZR402G. This unit does not have manual overrides and must be used in indoor applications only. The unit requires standard clean, dry, instrument air for reference air and span calibration gas, and also requires zero calibration gas.
