Pulp-temperature instrumentation for cold treatment

Built to the tolerance a cold treatment schedule demands.

Q: What is a USDA cold treatment sensor (probe)?

It is a temperature probe used to monitor and record pulp temperature during a USDA APHIS cold treatment protocol, which holds fruit at a set temperature for a fixed number of days to eliminate pests before entering a market like the United States.

Q: What's the difference between cold treatment schedules T107, T107-a and T108?

These are USDA APHIS schedules that set the required pulp temperature and duration: T107-a holds 1.11°C for 14 days, T107 holds 0.56°C for 16 days, and T108 holds 0.00°C for 18 days.

Q: Is this USDA probe certified or approved by USDA?

USDA does not certify individual probe brands; APHIS approves cold treatment facilities and protocols, not the sensor manufacturer. This is an independent manufacturer, not affiliated with or endorsed by USDA.

Q: Can I get a calibration certificate?

Yes, ISO/IEC 17025 accredited calibration is available through external laboratories on request, along with batch traceability and inspection records.

Q: Where can I buy a USDA probe for reefer containers?

These probes are supplied to reefer service networks, exporters and technical distributors across the United States, Chile and the rest of Latin America, Europe and Africa.

Stainless NTC probes for reefer containers, citrus and stone-fruit cold treatment, and sensor replacement programs — supplied across the Americas, Europe and Africa.

SCHEDULE REFERENCE ILLUSTRATIVE

1.11°C

SCHEDULE T107-a DAY 14 / 14

Pulp temperature held continuously within tolerance for the schedule's full duration — the standard this probe is built to meet.

Product

One probe, built around three things a cold-treatment audit checks first.

Accurate pulp-temperature reading, a sealed cable transition that survives a reefer cycle, and a paper trail that ties every unit back to its production batch.

FAQ

Questions a buyer actually asks before ordering.

What is a USDA cold treatment sensor (probe)?

It's a temperature probe used to monitor and record pulp temperature during a USDA APHIS cold treatment protocol — the process that holds fruit at a set temperature for a fixed number of days to eliminate pests before entering a market like the United States.

What's the difference between cold treatment schedules T107, T107-a and T108?

They're USDA APHIS schedules that set the required pulp temperature and duration: T107-a holds 1.11°C for 14 days, T107 holds 0.56°C for 16 days, and T108 holds 0.00°C for 18 days. Which one applies depends on the fruit, the pest risk and whether treatment happens in transit or in port.

Is this USDA probe certified or approved by USDA?

USDA doesn't certify individual probe brands — APHIS approves cold treatment facilities and protocols, not the sensor manufacturer. This probe is built to deliver the accuracy and batch traceability those protocols require. We're an independent manufacturer, not affiliated with or endorsed by USDA.

What sensor type and cable does the probe use?

A precision NTC thermistor in a stainless steel body, with a PUR marine-grade cable rated for refrigerated container and shipboard use.

Can I get a calibration certificate?

Yes. ISO/IEC 17025 accredited calibration is available through external laboratories on request, along with batch traceability and inspection records for every production run.

Where can I buy a USDA probe for reefer containers?
