Wireless Temperature Sensor

Tempsys offers a wide range of wireless sensors and probes to meet the needs of virtually any application. Our wireless temperature sensors can monitor temperatures down to -200º Celsius, as well as other vital parameters including humidity, carbon dioxide, oxygen, differential air pressure, particle count, and motion. Every sensor can alert if the refrigerator door is left open, the most common cause of a temperature problem.

Our wireless temperature sensors offer a variety of advanced features including a 30 day memory capacity, 24x7x365 data recording, two-way communication to ensure that no data is ever lost and immediate email or text message alerts to any number of necessary personnel in the case of a temperature failure. Our temperature sensors can also be used as a data logger for cold chain applications such as tracking the temperature of coolers for the transportation of blood products.

Our wireless temperature sensors:

  • Meet the stringent regulatory compliant healthcare and life sciences requirements
  • A2LA calibration certification traceable to NIST
  • Detachable Snap Cal probe simplifies annual recalibration

Questions to consider when selecting a remote temperature sensor:

  • What is the application environment?
  • What range of temperature do I need to monitor?
  • Do I need to monitor other vital data?
  • Do I need remote status alerts?
  • Do I need memory capacity? How much?
  • Does the sensor or probe meet compliance and auditory requirements?
  • How will the device be installed in the environment? Zip tie? Velcro? Mounted?
