This durable system can withstand temperatures up to 230°C when completely submerged and 350°C in dry heat applications (enclosure o-ring removed). The ThermoVault1000-P is easy to use, simply open the enclosure, insert the Temp1000P, thread the probe through the end cap and latch it back onto the barrier body. The Thermovault1000-P is built for use in applications that required extreme temperature monitoring, such as with furnace profiling, geothermal down-hole recording, and oven data logging.
