Product Notes
The PRTemp140 is a pressure and high temperature data logger all in one, created specifically
for use in autoclave validation, mapping studies and pressurized processes. Featuring the
familiar body style of the 140 series of data loggers and made of rugged stainless steel, this
dual purpose device is less than 2.5 inches in length, allowing it to fit discretely inside small
spaces. The PRTemp140 is able to measure and record temperatures from -20 °C to 140 °C,
and pressure from 0 bar to 5 bar, accommodating a wide range of applications even in the
harshest conditions.
Submergibility
The PRTemp140 is fully submersible and is rated IP68.
O-Rings
O-ring maintenance is a key factor when properly caring for the PRTemp140. The O-rings
ensure a tight seal and prevent liquid from entering the inside of the device. Please refer to
the application note “O-Rings 101: Protecting Your Data”, found on the MadgeTech website,
for information on how to prevent O-ring failure.
Note: This product is rated for use up to 140 °C. Please heed the battery warning. The product will explode if exposed to
temperatures above 140 °C.
