IMPORTANT PRECAUTIONS
All sensor designs are made for air monitoring @ 1 atm +/- 0.2 atm. Because applications of use and
device implementation are outside our control, SPEC Sensors cannot guarantee performance in a given
device or application, and disclaims any and all liability therefore.
Customers should test under their
own conditions to ensure the sensors are suitable for their requirements.
Contact the factory to discuss specific concerns that might damage the sensor performance or life.
Condensation and Water (1)
Salt Water Contamination (1)
High Temperature Operation (> 70C) for more than 1 month
Low Humidity Operation (< 15% RH) for more than 3 months
High Bias voltage
Highly contaminated air over a prolonged period
High levels of particles or soot (unless proper filtering is provided)
(1) Use of porous PTFE membrane or filter cap may address this concern)
MARKING INFORMATION
All gas sensors are tested and marked at the SPEC Sensors factory. Sensors include a label with an alpha-
numeric code and a two-dimensional bar code. The codes include the information indicated in the table
below.
PRODUCTION DATA information is current as of publication date.

SENSOR STORAGE, HANDLING AND SOLDERING
This information embodies various general recommendations concerning the storage, handling, and manual soldering
conditions for SPEC SENSORS CSPEC Modules. It is only applicable for modules guaranteed by SPEC SENSORS
stated in SPEC SENSORS Sensor Specification Sheet. Moreover, SPEC SENSORS' modules are NOT warranted
and should NOT be used in high temperature soldering (reflow) or pre-tinning baths.
Sensor & Module Handling
Handle sensors with care. Take precautions, including but not limited to the following:
A. DO NOT apply excessive pressure to the top or bottom of the sensor module.
B. Whenever possible, handle or make contact with the sensor module from the sides of the PCB or substrate.
C. Light vacuum pressure is possible during handling, DO NOT apply vacuum over gas sensor port.
D. If the sealed sensor package is opened, DO NOT re-seal using vacuum or nitrogen gas. DO NOT reseal with
desiccant.
E. DO NOT obstruct the gas sensor port by making direct contact with any tape, apparatus, weights, etc.
F. DO NOT use silicone or other conformal coatings around the sensor or gas port-holes.
G. Operators are requested to wear powder free antistatic gloves.
Manufacturing Assembly Floor Environment
SPEC SENSORS recommends that the manufacturing assembly floor environment be maintained at controlled
conditions:
A. Temperature: 18 - 26°C
B. Relative Humidity: 40 to 60%
C. Pressure: 1.0 ± 0.2 atm
Sensor & Module Storage Conditions
The shelf life for sealed, packaged components is 12 months from the pack seal date, when stored in the factory-
sealed bag under the following conditions:
A. Temperature: 5 to 25 °C
B. Relative Humidity: 20 to 80%
C. Pressure: 1.0 ± 0.2 atm
D. Storage Time: 12 months
When moving from Storage Conditions to the Manufacturing Assembly Floor Environment, the sensors should be
allowed to equilibrate at the new conditions for at least 24 hours prior to manufacturing.
Module Attach Soldering Process
Hand solder only. Keep the soldering iron or solder process tool away from the sensor. The sensor should not see
pre-heat temperatures above 70 °C. There have been suggested cases where a heat sink cover over the sensor may
be applicable to protect the sensor during processing. No Application notes to this approach available. Only to be
used as reference only.
A. DO NOT heat sensor above 70 °C
B. Hand or peripheral process type approach
C. Use solder wire alloy with the lowest possible eutectic temperature
D. Use lowest possible soldering iron temperature
E. Contact the host board with the soldering iron at a 45° angle on the solder pad
F. Keep the soldering iron away from the top and bottom of the sensor module
G. DO NOT place in reflow, wave or IR reflow type processes
H.
DO NOT place mounted board In a wash
