Calibration Options

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 applicaitons only. The unit requires standard clean, dry, instrument air for reference air and span calibration gas, and also requires zero calibration gas.

Filtters

M1234SE-A (Self-Cleaning) and M1200DB-06 (Standard) Fly-Ash Filters

The accumulation of fly-ash on the zirconia cell affects its ability to measure oxygen concentration.

Fly-ash and its constituents can reduce the life of the zirconia cell and affect the cells response time

to changes in gas concentration. Yokogawa’s large surface area sintered metal filters are designed

to keep particulate and ash off the measurement cell.

E7042UQ Oil/Gas Dust Filter

This filter is used to protect the cell from corrosive dust components in natural gas or oil-fired applications.

Cables

WZ-H Heater and Signal Cabling

Two cables are needed to connect a ZR22 to an AV550G or ZR402G. One heater cable set is necessary to send power from the analyzer to the heater assembly on the probe, and one signal cable set is used to provide the analyzer with information about the probe’s cell voltage, thermocouple reading, and remote junction temperature for compensation. We recommend running these cables in separate conduit to avoid heater wires having an affect on the signal wire readings.
