Products

•  NTC Temperature Probes

•  NTC thermistor probes are available in a variety of configurations to meet your needs. Choose between our Liquid Probes, Surface Sensors and Gas Air temperature sensors.

•  Miniature NTC Sensors

•  Quality Thermistor, Inc. (QTI) offers a full range of surface mount as well as leaded miniature thermistors. These small thermistors can be used in a variety of applications ranging from body temperature measurement to thermal profiling of electronics. QTI can also build temperature sensor to meet your exact requirements. Most products can be supplied with RoHS or non-RoHS materials.

•  Instrumentation

•  Looking for an easy to use and highly accurate temperature measurement system? QTI has developed a precision USB thermometer that's accurate to +/-0.1°C from freezing to boiling.

•  Surface Mount Thermistors

•  Available in Commercial Level, Military Level and Space Level.

•  NTC Thermistor Elements

•  NTC thermistor elements are available in a variety of configurations to meet your needs. Choose between our surface mount or leaded parts, both configurations are offered for either commercial or Military/Space level applications.

•  PTC Thermistor Elements

•  Positive Temperature Coefficient (PTC) thermistors exhibit increasing electrical resistance with increases in environmental temperature and decreasing electrical resistance with decreasing temperature.

•  Military & Space Thermistors

•  For over 20 years, Defense sub-contractors have relied upon Quality Thermistor's thermistor components in their most critical applications. QTI's high reliability thermistors are built to meet or exceed the MIL-R-23648 military specification. We continue to maintain one of the largest QPL (Qualified Product Listing) product offerings of any other supplier. QTI's in house test lab is equipped to test all of the Group A, B, and C requirements of MIL-PRF-23648 to ensure product quality under hostile environments

•  Sometimes there’s no room for error – like when you’re heading to Mars! Quality is inherent to our process, but we take it to the extreme when manufacturing high cost of failure NTC & PTC thermistors to NASA GSFC spec! QTI was the first thermistor manufacturer to work with the Defense Supply Center Columbus to develop a new Military specification M32192. Now, in conjunction with the NASA Goddard Space Flight Center, it has developed a new specification for high cost of failure NTC and PTC thermistor temperature sensors!

Applications

•  Alternative Energy

•  Monitoring system temperature is critical to keep high-technology equipment running at peak efficiency. From alternative fuel automobiles to wind turbines, QTI offers a variety of temperature sensors to fit your need. In addition, we offer a full line of lead free parts to comply with RoHS standards. Some typical systems in an automobile where temperature is measured could be engine coolant temperature, transmission fluid temperature, cabin air temperature, ambient air temperature and many others. Consider an NTC thermistor based temperature sensor for any automotive temperature sensing application.

•  Defense & Aerospace

•  For over 30 years, Defense sub-contractors have relied upon Quality Thermistor's thermistor components in their most critical applications. QTI's high reliability thermistors are built to meet or exceed the MIL-R-23648 military specification. We continue to maintain one of the largest QPL (Qualified Product Listing) product offerings of any other supplier. QTI's in house test lab is equipped to test all of the Group A, B, and C requirements of MIL-PRF-23648 to ensure product quality under hostile environments.

•  Medical Diagnostic Equipment

•  Medical grade temperature sensors can be supplied in a variety of forms to help fit your particular application. Typically, NTC thermistors are the ideal solution for monitoring temperature at 37°C (normal human body temperature). NTC thermistors can provide unparalleled accuracy and sensitivity in the body temperature range. Additionally, because of their low cost at high volumes, thermistors are the perfect temperature sensor choices for disposable medical applications.

•  Telecommunications

•  As technology pushes the telecommunications technology envelope for higher and higher performance, communications systems design engineers must monitor and compensate for a wide range of temperatures found in typical communications installations. NTC surface mount thermistors are an ideal solution for monitoring the temperature at the board level. PTC surface mount thermistors are a great choice for applications requiring in-circuit temperature compensation for the silicon-based semiconductors found in most telecommunications equipment.

•  Consumer/Industrial

•  Consumer electronics are packing more and more semiconductors in smaller and smaller packages. As part density increases in any product, the heat generated by the device becomes a design concern. Temperature monitoring becomes a concern when charging and recharging batteries in some electronic devices, an NTC thermistor is an ideal solution for accurate temperature measurement in confined spaces.

•  HVAC

•  NTC Thermistors are the most commonly used temperature sensors for the HVAC & R industry. Air temperature measurement is commonly monitored, in addition, airflow also can be determined by using NTC thermistors in a self-heating mode. QTI has a great deal of experience manufacturing standard thermistors as well as for harsh environments.
