Military / Space Level Thermistors
An AS9100 company, QTI manufactures Mil-Spec and Space Level thermistors for high cost of failure applications. QTI's (hi-rel) high reliability thermistors are built to meet or exceed the requirements of MIL-PRF 23648 and MIL-PRF 32192, and NASA GSFC S-311-P-827 and S-311-P-18 specifications. QTI manufactures both fully assembled and tested temperature probes as well as discrete temperature sensor components.
USB Thermometers
Available from QTI are precision USB thermometers accurate to +/-0.1°C from freezing to boiling (0°C to 100°C). Available in both plug and play HID as well as serial UART, DirecTemp™ USB thermometers can easily be configured to fit your temperature sensing needs.
IP68-Rated Waterproof Temperature Probes
QTI's Hydroguard IP68 series combines a highly stable precision thermistor with an extremely durable waterproof housing. This temperature sensor offers excellent performance during harsh freeze-thaw cycles, and is ideal for use with discharge lines, evaporator fins, evaporator coils, and cabinet temperature applications.
