Top 5 Best ELDs With Reefer Monitoring: 2026 Picks
Rules, prices and device details on this page were checked October 2026 against the official sources listed at the bottom. Where a provider doesn't publish a number, we say so instead of guessing.
Refrigerated carriers have two jobs at once: keep the driver legal and keep the load cold. An ELD handles the first. Reefer monitoring handles the second. Running both on one platform saves you a second login, a second vendor and a second set of hardware. We looked at five ELD providers that offer reefer or cold chain monitoring and compared what each one does.
Reefer Telematics
Reefer monitoring connects to the trailer's refrigeration unit or to separate temperature sensors inside the trailer. It reports setpoint, return and discharge air temperatures, unit status and fuel level, depending on the setup. The value comes from three things:
- Live alerts. Know right away when temperature drifts or the unit shuts off, so the driver can fix it before the load spoils.
- Remote control. Some systems let dispatch change setpoints or restart a unit without the driver stopping.
- Temperature history. A time stamped record of the whole trip, which you can hand a shipper or receiver when there's a claim.
Reefer monitoring is a type of asset tracking and part of a wider telematics setup. If your trailers aren't always hooked to the same truck, you'll want trailer side hardware that reports on its own.
Top 5 ELDs With Reefer Monitoring
1. Samsara
Samsara has a dedicated reefer monitoring product that sits alongside its ELD, GPS and camera tools. It tracks temperatures and reefer status, sends alerts when things go out of range and keeps a temperature history you can share. Since it's all in one platform, dispatch sees the truck, the driver's hours and the trailer temperature on the same screen. Contracts typically run three to five years, so it fits larger reefer fleets best.
2. Motive
Motive offers a reefer monitoring system that tracks temperatures and unit status alongside its ELD, dash cam and fleet tools. You get alerts and history in the same dashboard you use for logs. It's quote based, and pairs well with its asset trackers if you run a pool of trailers.
3. Geotab
Geotab offers cold chain management for fleets that haul temperature sensitive goods. It works with the open Geotab ecosystem, so you can mix reefer integrations, sensors and partner tools from the marketplace. That flexibility is a big plus for fleets with trailers from different makers. Pricing comes through resellers.
4. Omnitracs
Omnitracs supports reefer monitoring through its trailer tracking solution. It's long been popular with large carriers, including refrigerated fleets, and ties temperature data into its broader fleet management platform.
5. EROAD
EROAD offers cold chain monitoring along with its ELD and fleet tools. It's a good choice for fleets that want temperature compliance records alongside their logs from one provider.
Another route is Platform Science, which offers reefer connections through its marketplace. That's useful if your fleet already runs that platform.

FSMA Requirements
If you haul food, the FDA's Sanitary Transportation rule under the Food Safety Modernization Act applies. You don't need a specific device, but the rule sets out what carriers must be able to do. Under 21 CFR 1.908(e), carriers responsible for temperature control must:
- Pre cool the trailer before loading if the shipper requires it, and be able to show it was done.
- Give the operating temperature to the shipper or receiver when asked.
- Be able to show that the required temperature was kept during transport. That can be done with ambient temperature readings at loading and unloading, or with temperature data recorded during the trip.
Under 21 CFR 1.912, carriers also need to keep written procedures and training records. These must be kept for 12 months beyond when you use them.
Reefer monitoring makes all this much easier. A continuous temperature log for every trip is strong evidence that you kept the load in range, and many systems can export a trip report for the receiver in a few clicks.
Pricing
None of these five publish a reefer monitoring price, so you'll need quotes. Pricing usually includes trailer hardware or a reefer integration, plus a monthly fee per trailer on top of your ELD license. To compare fairly, ask each vendor for:
- The hardware cost per trailer and whether install is included.
- The monthly fee per trailer.
- Which reefer unit makes and models they support.
- Whether alerts, remote control and history exports cost extra.
- The contract term for the reefer product and the ELD.
Also confirm that the ELD part is on the FMCSA registered ELD list. A great reefer tool doesn't help if your logs aren't compliant.
Setting Up Alerts That Work
Reefer monitoring only helps if someone acts on the alerts. Too many alerts, and people start ignoring them. Too few, and a load warms up without anyone noticing. A few setup tips:
- Set a temperature band for each load type, not one setting for everything.
- Add a short delay so door openings at a dock don't trigger false alarms.
- Send critical alerts to both the driver and dispatch.
- Alert on unit shutdown and low reefer fuel, not only temperature.
- Review alert history each week to spot trailers or units that keep causing trouble.
Also decide who owns the temperature report for each load. When a receiver questions a delivery, having the trip report ready in minutes can settle the claim before it turns into a rejected load.
Finally, train drivers on what to do when an alert comes in. A clear checklist for checking the unit, calling dispatch and noting the event keeps everyone calm and creates a record of how the problem was handled, which also helps with FSMA training records.
A little homework up front saves a lot of money and frustration over the life of the contract, so take the time to compare carefully.
How to Choose
Start with your trailers. If you run mixed reefer units from different makers, an open platform such as Geotab makes integration easier. If you want everything in one tightly built system, Samsara or Motive are simpler to manage. Large fleets already on Omnitracs or Platform Science may find their current vendor's reefer option is the easiest path. Whatever you choose, test it on a few trailers first and check that the alerts reach the right people at the right time.

Frequently Asked Questions
Do ELDs monitor reefer temperatures?
The ELD itself handles logs, but several ELD providers sell reefer monitoring on the same platform, including Samsara, Motive, Geotab, Omnitracs and EROAD.
Does FSMA require a temperature recorder?
No specific device is required, but carriers must be able to show the required temperature was maintained, either with readings at loading and unloading or with recorded temperature data.
How long must FSMA records be kept?
Under 21 CFR 1.912, written procedures and training records must be kept for 12 months beyond their use.
How much does reefer monitoring cost?
None of the five providers here publish a price. Expect a hardware cost per trailer plus a monthly fee, so request quotes.
