Our take
CEM's DT-131 is one of the better-specified contact thermometers in this group. Its model page identifies it as a digital food thermometer and lists a −40°C to 250°C range, 0.1-degree resolution, 1.5% plus 2-degree full-scale accuracy, a two-second response and a 120 mm probe. The page also describes HOLD and MAX/MIN. A candidate-ASIN-indexed manual supports the historical association, but the Amazon candidate itself remains unverified. This is a documentation-led choice, not a claim about hands-on performance.
A cook or food-service buyer who values a model-specific specification sheet and contact probe more than a wireless display or a confirmed Amazon variant..
Look elsewhere if you require a confirmed backlight, magnetic storage, remote monitoring, or an exact Amazon listing. The saved CEM page does not confirm the historical backlight or magnet wording, and the candidate-ASIN association comes from an indexed secondary manual record. Also check whether the listed accuracy formula fits your operating point; a percentage-plus-offset specification is not a fixed maximum error across every reading.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- CEM publishes a wide model-specific range from −40°C to 250°C and 0.1-degree resolution.
- The manufacturer gives a two-second response and 120 mm probe length, which helps compare it with other contact tools.
- HOLD and MAX/MIN are described by the manufacturer, along with automatic shutoff and an LR44 battery.
What to weigh up
- The historical candidate ASIN is associated through an indexed manual page rather than a verified current Amazon listing.
- The manufacturer page does not support the historical magnet or backlight claims, so neither should be assumed.
- The accuracy statement is 1.5% plus 2 degrees over the full scale; buyers must consider the formula rather than read it as a uniform one-degree tolerance.

Full review: how the features affect your choice
What the features mean for you
A contact instrument with a model-specific source
CEM's product page identifies the DT-131 as a professional digital food thermometer that measures through a contact probe. That source is materially stronger for technical comparison than a broad marketplace title because it names the model and publishes operating details. A separate candidate-ASIN-indexed manual page supports the historical association with B07DHLW7XV, but it does not establish that every current Amazon result is the same variant. Keep the CEM model and historical candidate linked as a lead while using an exact-model search for purchase. The manufacturer page is the basis for its specifications; the ASIN association remains a separate, narrower piece of evidence.
Range, resolution and an accuracy formula
CEM lists a measurement range of −40°C to 250°C, equivalent to −40°F to 482°F, and a resolution of 0.1 degree. It also publishes accuracy as 1.5% plus 2 degrees across the measurement scale. That formula is more informative than no accuracy statement, but it is not a single fixed error value that can be applied without considering the reading. The listed maximum temperature also does not mean every probe or body component can be exposed to that environment indefinitely. Use the manufacturer's range as a comparison point and read the instructions for insertion depth and operating conditions before relying on it in a particular workflow.
Probe dimensions and response
The DT-131 product page lists a 120 mm probe and a two-second response. Those details help a buyer compare reach and the stated sampling pace with a typical spot-check routine. The page says the probe should be inserted at least halfway into the measured medium and that the reading appears on the LCD. The response figure is a manufacturer specification, not a result from our own timed test. The saved evidence does not describe the exact sensing-zone location or give a numeric probe diameter, so do not infer those dimensions from the model picture. Compare the stated length with the thickness of your usual cuts and follow the manual's handling instructions.
HOLD, MAX/MIN and battery operation
CEM describes a HOLD function for retaining a current reading and a MAX/MIN display mode. It also says the thermometer switches off automatically after about twenty minutes and uses an LR44 battery. These are useful practical details when the cook needs to record a temperature without keeping the probe in place. The product page includes Celsius and Fahrenheit selection. Those controls distinguish the DT-131 from simpler digital models that publish only a range. They do not establish a wireless connection, alarm, or data-logging function; no such feature is supported by the saved source. The historical magnet wording is also not confirmed on the manufacturer page.
What the documentation does not establish
The manufacturer page supplies a substantial specification set, yet it does not confirm the listing's historical magnet or backlight claims. It also does not provide a splash-resistance rating or wireless feature. Treat these absences as unknown rather than proof that the device lacks each feature. The candidate ASIN is supported by a third-party manual index, not an exact current Amazon product page, so the purchase link searches for DT-131. Check the delivered model and market version against the CEM instructions. For a food-service setting, confirm any required local certification and calibration procedure directly with the supplier instead of treating the listed accuracy formula as a substitute for workplace validation.
Compare for your needs
Compare CEM DT-130 for a related contact thermometer with its own separate model specifications, or Oregon Scientific AW129 if you need a remote probe and receiver. Do not transfer DT-131's probe length or functions to DT-130.

Before you buy
What is the DT-131's stated range?
CEM lists −40°C to 250°C, also shown as −40°F to 482°F. The page separately lists an accuracy formula of 1.5% plus 2 degrees over the full scale.
Does the DT-131 have a magnet or backlight?
The saved manufacturer product page does not establish either historical claim. Treat both as unknown and verify them from the exact version's documentation if they matter.
Is B07DHLW7XV confirmed as the current exact Amazon listing?
No. A candidate-ASIN-indexed manual record supports the historical association, but the exact current US listing remains unresolved. The purchase link searches for the DT-131 model.
Where can I check the current price?

The decision
The CEM DT-131 is a strong documentation-first option for buyers comparing a contact food thermometer by range, resolution, response and named controls. The model page makes its core specification set unusually clear, while the historical ASIN, backlight, magnet, splash rating and market variant still need verification. Use the exact model search and confirm the delivered DT-131 before relying on it for a defined process.
