More info

The DHS Data Logging System for Dry Heat Sterilization is an all-in-one solution that comes equipped with:

• HiTemp140-M12, High Temperature Data Logger
• 36 inch Glass Braided RTD probe with M12 connector and flat probe tip
• ThermoVault Max, Extreme Temperature Thermal Barrier

This system is capable of withstanding and measuring temperatures up to 400 °C, allowing it to record throughout the entire sterilization process. The HiTemp140-M12 data logger features the popular rugged steel body design of the HiTemp140 data logger series with the flexibility to utilize dozens of RTD probe options with M12 connection compatibility.

The MadgeTech software allows for fast and easy data logger configuration. Simply insert the data logger into the IFC400 or IFC406 docking station (sold separately), choose either immediate or delay start and the desired reading rate. Insert the data logger onto the ThermoVault Max enclosure and screw the cap back on securely. The device is ready to be deployed.

This system is not IP rated and is for use in dry applications only.
