Uses

Teledyne can retrofit InstaTrace sensing capability into all of its Micro-fuel Cell based trace oxygen analyzers currently in service. The retrofit kit contains the cell holder in addition to the InstaTrace sensor. Simply replace the old cell holder (the bottom piece that either threads or mechanically clamps to the cell block assembly) and install the InstaTrace sensor. Take advantage of this innovation by ordering the appropriate retrofit kit.

Installation

​It is important to minimize the amount of time a Teledyne trace oxygen sensor is exposed to air during the installation process. The quicker the sensor can be installed into the unit, the faster your sensor will recover to low oxygen measurement levels.​

​

Before installing a new cell, check the O-ring in the base of the cell holder. Replace it if worn or damaged.

Place the cell on the holder with the screen side facing down.

NOTE: There is a small location hole drilled in the holder. This hole mates with a guide pin on the bottom rear of the cell block. The hold in the cell block holder must align with the guide pin on the cell block.

CAUTION: Do not touch the sensing surface of the cell. It is covered with a delicate Teflon membrane that can leak when punctured. The sensor must be replaced if the membrane is damaged.

  • STEP 1: Remove power from instrument.

  • STEP 2: Remove the ol​d sensor (if installed) from the analyzer.

  • STEP 3: Purge the analyzer at approximately 1 SCFH flow rate with N2 (or applicable sample gas with the sensor holder removed.)

  • STEP 4: Remove sensor from double bag storage.

  • STEP 5: Remove sensor shorting button.

  • STEP 6: Place the sensor inside the cell block.

  • STEP 7: Hold the sensor up into the block while positioning the cap under the sensor. Vigorously push the cell holder with the sensor into the cell block, thus puncturing the protective film / seal cover.

  • STEP 8: Push the gate on the cell block down so that the slots on the side of the gate engaged the locating screws on the side of the block. This forces the holder into position and forms a gas-tight seal.

  • STEP 9: Purge system with sample or zero gas.

  • STEP 10: Power up.

Your InstaTrace sensor will typically reach a stable low value within 30 minutes or less of installation.​​​​
