PickfolioThe TP19H is a fold-out, instant-read digital thermometer. Its maker lists a 1-second response, a temperature range of -58 to 572 °F, accuracy of ±0.9 °F between 14 and 212 °F, a 4-inch probe, IP65 water resistance, a lock and calibration function, and an auto-rotating backlit display. It suits quick spot checks like the three turkey readings. It is not a leave-in probe, so it can't monitor a roast while the oven is closed.
Good fit if
- Quick spot checks at the end of cooking — turkey, chicken, steaks, fish
- Left- or right-handed cooks (the display flips 180°)
- Kitchens where you want a thermometer you can check yourself for accuracy
Not ideal if
- Watching a roast's temperature continuously without opening the oven — that's a leave-in or wireless probe's job
- Surface temperatures of pans or griddles — that needs an infrared thermometer

What it is
The TP19H is a pocket-size digital thermometer with a probe that folds out of the body. You open the probe, insert it, and read the number. Its maker's US site — buythermopro.com now forwards to temppro.com — lists it as the TempPro TempSwift PLUS TP19H 1. Many store listings still call it the ThermoPro TP19H; it's the same model number.
What the maker documents
These figures are the maker's own, from its product page 1. We haven't measured them.
| Spec | Maker's figure |
|---|---|
| Response time | 1 second 1 |
| Temperature range | -58 to 572 °F (-50 to 300 °C) 1 |
| Accuracy | ±0.9 °F (±0.5 °C), stated for 14 to 212 °F 1 |
| Probe | 304 stainless steel, 4.00 in (103 mm) 1 |
| Sensor | NTC 1 |
| Water resistance | IP65 1 |
| Display | Backlit, auto-rotates 180° 1 |
| Extras | Temperature lock, calibration function 1 |
| Power | 1 × AAA battery, 1.5 V 1 |
Two details worth noticing. First, the ±0.9 °F accuracy figure is stated for 14 to 212 °F, not for the whole range 1 — fine for checking meat, but don't assume the same accuracy for deep-frying oil. Second, it has a calibration function 1, so you can run the ice-water check and correct it.
How it turns on and off
According to the maker, opening the probe turns it on and closing it turns it off. It goes to sleep after 90 seconds of inactivity and wakes when picked up 1. So the habit to build is simple: fold the probe back when you're done.
Using it for a turkey
A quick-reading probe suits the job USDA describes for whole poultry: checking the innermost thigh, the innermost wing and the thickest part of the breast near the end of cooking 2. Our turkey guide walks through the three spots.
Limitations
- Not a leave-in probe. USDA advises against leaving a food thermometer in food while it cooks unless its maker says it's designed for that 2, and the TP19H is presented as an instant-read tool 1. You'll need to open the oven to check. If you want to watch the temperature with the door closed, look at a wired or wireless leave-in probe instead.
- Accuracy is specified for a range. The ±0.9 °F figure covers 14 to 212 °F only 1.
- IP65 means splash-resistant, not submersible. The maker says to rinse it under running water and dry it 1; don't drop it in the sink to soak.
- Battery-powered. It runs on one AAA cell 1; keep a spare before a big cooking day.
Checklist: before you rely on it
- Run the ice-water check and confirm it reads 32 °F 2, adjusting with the calibration function if needed 1.
- Practice the three turkey spots so you know how deep the probe needs to go.
- Keep a spare AAA battery in the drawer 1.
- After use, rinse under running water, dry with a soft cloth and store with the probe folded, as the maker advises 1.
