ThermoWorks Therma 20 Plus with 174-166 Probe Review
This solidly-built, full-featured thermometer and probe are built to last in environments that would ruin most equipment. Accuracy is excellent. It has all the features except for a very quick response time. The maximum temperature is 302ºF (150ºC) which might limit its functionality for some users. It cannot be left in the oven/grill while cooking, and no in-food/in-cooker probes are offered for this unit.
This thermometer is designed to work in wet environments that would kill most other thermometers. Both the display and the probe are built to commercial standards. The entire package is protected to IP66/67 standards, meaning it will survive under a faucet or completely submerged. It uses a thermistor sensor so it won’t respond as quickly as a good thermocouple probe with a small-diameter tip. That’s not to say that it’s slow, it will go from ice water to boiling water in about 16 seconds, not a huge imposition.
The display is a large 0.66″ (15mm) with a button-activated backlight. It has a min/max feature and a hold button. The unit will auto-shutoff after 10 minutes, but this can be disabled by pressing the Hold button while powering-on the unit. It will revert to auto-off when manually turned off. Battery life is claimed to be 10,000 hours, so you may never have to replace them. The thermometer comes with a zippered case to hold it and its probe.
The manufacturer’s contact info, including address, website, and telephone number, is found in the instruction sheet. The unit is covered by a 2 year limited warranty. A certificate of calibration is included with the thermometer.
At nearly $200 for the complete unit, this isn’t for everyone. However, if you want a bullet-proof thermometer that will survive in a wet environment, one that will provide excellent accuracy and is solidly-built, then this would be a good choice. The somewhat slow response time and the limited temperature range conspire to reduce this unit’s rating to a Silver medal.
