Wireless meat temperature loggers MADGETECH / MadgeTech, Inc. series RFOT

Wireless probes MADGETECH / MadgeTech, Inc. series RFOT with piercing needles are designed for continuous thermal monitoring of meat and poultry inside smokehouses and ovens. Devices transmit real-time data via radio channel supporting strict food safety standards.

Two-way wireless communication at 2.45 GHz based on IEEE 802.15.4
Food-grade stainless steel piercing needle with diameter from 1.6 to 4.8 mm
Rugged splash-proof housing enclosure engineered to IP67 ingress protection
RFC1000 wireless repeaters ensuring stable link through thick oven walls

Autoclave validation and thermal mapping

For thorough validation of autoclave thermal uniformity, MADGETECH / MadgeTech, Inc. HiTemp140 series data loggers are positioned across critical points of the chamber volume.

Internal non-volatile memory retains up to 32,700 readings with user-selectable intervals starting from one second, enabling precise tracking of vacuum pulses, steam injection, dwell exposure and drying phases.

The stainless steel housing structure withstands saturated steam under pressures up to 60 PSIG, delivering continuous thermal profiling without unreliable feed-through wires.

Synchronous steam pressure monitoring and F0 calculation

Comprehensive evaluation of steam sterilization cycles requires simultaneous recording of temperature and steam pressure, pairing thermal units with MADGETECH / MadgeTech, Inc. PR140 submersible pressure loggers.

The devices endure pressure up to 5 bar and retain calibration precision under hot condensing steam.

The companion software computes thermal lethality F0 by correlating core product temperature with chamber pressure dynamics, preventing undetected air pockets that could impair sterilization efficiency.

Maintenance protocol for O-Ring sealing rings

Reliable environmental sealing of MADGETECH / MadgeTech, Inc. logger enclosures under repeated high-temperature heating and cooling cycles depends on timely maintenance of elastomeric O-Ring seals.

Prior to each autoclave run, operators inspect the sealing rings for micro-fissures, deformation or particulate debris, applying a uniform film of high-temperature lubricant to the threaded battery cap.

Routine replacement of worn sealing kits prevents hot condensate ingress, protecting sensitive microelectronics and lithium power cells from moisture exposure.

Mounting loggers into canning containers and retorts

During thermal pasteurization and retort processing of packaged food products, MADGETECH / MadgeTech, Inc. HiTemp140-CF instruments mount directly into metal cans, flexible pouches or glass jars via CF200 adapter fittings.

Threaded mechanical bases provide hermetic seals while rigid probes position precisely at the cold spot of the food container. The IP68 submersible body resists organic food oils, sauces and chemical washdowns, permitting accurate mapping in batch retorts and continuous hydrostatic cookers.

Wireless monitoring for smokehouses and cooking ovens

For continuous cooking and smoking operations in meat processing facilities, MADGETECH / MadgeTech, Inc. RFOT wireless loggers feature flexible piercing probes that track internal product temperature.

The instruments transmit live telemetry at 2.45 GHz using IEEE 802.15.4 protocol via RFC1000 wireless repeaters back to a central workstation.

This eliminates the need for operators to open oven doors for manual core probing, minimizing heat loss and maintaining unbroken thermal history in accordance with HACCP rules.

Compliance with FDA 21 CFR Part 11 software standards
