Nextteq Thermal Ring Kit User Manual

Thermal Ring Introduction

Results from under-reported or over-reported chemical levels can cre­ate an unsafe condition. The Thermal Ring increases safety and reduc­es risk by allowing you to accurately correct for temperature changes
on-the-spot, without additional equipment like alcohol and infrared
thermometers.

Because detector tubes are calibrated at a specific temperature, in­creases or decreases from this temperature can impact the reading.
The instructions that come with each pack of detector tubes advise if
there is a need for temperature correction. (For a complete list of tubes,
and indication of those needing temperature correction, consult Gas­tec’s Detector Tube List or the Gastec Handbook, both available from
Nextteq, LLC.) The instructions will provide either a table with correc­tion factors or a table listing true concentrations based on the ambient
temperature. For accurate results, ensure the tube has been at ambient
temperature for 15 minutes before testing.

The Thermal Ring, which is af­fixed to all new Gastec GV-100
pumps, is perfectly calibrated
to work with the Gastec Gas
Sampling Pump and Detec­tor Tube Systems. Please see
other side for instructions on
affixing the Thermal Ring and
warning label to a GV-100
pump in the field.

Thermal Ring Instructions

The instructions below will enable you to affix the new thermal ring
and warning label to an existing Gastec GV-100 pump.

Thermal Ring

1. Determine location of the back plate of the GV-100 Gas Sam­pling Pump and find the raised area on the back plate.

2. Detach the thermal ring from its backing and beginning at
corner of the raised area, affix the thermal ring around the back
plate.

Raised Area

Warning Label

1. Find the engraved lettering that says “50/100ml” and position
the pump with the arrow facing you.

Lettering

2. Detach the warning label from its backing and affix the warning
label to the pump 3/8” from each side of the engraved lettering.

CAUTION: The detector tube temperature affects the reading, not ambi­ent temperature. The thermal ring measures ambient temperature. For
accurate results, ensure the tube has been at ambient temperature for 15
minutes before testing. Then use the temperature displayed on the thermal
ring for temperature correction.
