How does your sensor warranty work?
Maxtec offers the best warranties in the industry. Most of our sensors come with their own TWO year warranty, separate from that of the TWO year warranty on our analyzers. All of our sensors have equal or greater warranties than that of the OEM. The clock for the warranty on all Maxtec products begins when the sensor ships from Maxtec.
What is the most effective method for storing my sensors?
- Store sensors upright with the membrane facing down at room temperature
- Absolute shipping/storage temperature range is -15 to +50°C (+5 to +120 °F)
- Use FIFO inventory management to keep sensors fresh
- Do not expose sensors to vacuum, high pressure, shock or vibration
- Do not expose sensors to acidic or organic solvent vapors, chlorine (bleach), ozone or dust
- Recognize that pressure, temperature, relative humidity and exposure to oxygen will all affect the useful life of galvanic oxygen sensors
What is involved in submitting a warranty claim?
You simply need to call Maxtec with the serial number. If the sensor is under warranty, the Maxtec Customer Service representative will provide you with an RMA number. If a sensor is under warranty, Maxtec requests that the sensor be sent back to Maxtec so it can be tested. This process helps Maxtec to identify problems and notice problematic trends that a sensor may have. Please send all sensors to 6526 South Cottonwood Street, SLC, UT 84107.
How can I obtain the best performance from my oxygen sensor?
{MAX-250 series} oxygen sensors are designed for industrial and medical environments. The best performance can be obtained by following these guidelines:
- Do not install sensors with the sensing surface facing upwards. For optimal performance and life characteristics, sensors should always be mounted with the sensing surface pointing down or horizontal
- Do not expose the sensor to gas sample streams outside the range +15 to +40°C (+60 to +105 °F), or relative humidity greater than 95% (non-condensing)
- Do not expose sensors to pressures outside the range 1.0 ± 0.5 atmospheres
- Do not expose sensors to excessive shock or vibration
- Sensors should be located away from thermal gradients (fans, heat sinks, etc)
- Associated instrumentation should be designed so that the minimum operating load on the sensor is 1MΩ
- Do not expose sensors to voltage bias or design circuitry which could attempt to electrically charge or discharge the sensor
Is a sensor included when I purchase a new analyzer?
Yes. Every analyzer quoted or sold includes both the analyzer and the sensor. This is not always true with all oxygen analyzer manufacturers.
Can Maxtec customize sensors to my specifications?
Yes. Maxtec has been manufacturing oxygen sensors for over 15 years and offers oxygen sensor solutions for multiple large OEM companies, world-wide.
