Lot of 2 thermometers hygrometers
Jedew ROUND
Best Lot of 2 thermometers hygrometers – Budget – 0 $ to 15 $
The JEDEW ROUND is our Budget choice for simple, local monitoring in small spaces. Its compact two-pack gives you more than one reading point, and buyers generally like the clear display, size, and everyday usefulness. Good Prints 3D also found it practical for checking humidity in closed filament-storage containers without an app. Choose it when a quick visual reading matters more than remote alerts or a humidity history.
The JEDEW ROUND earns our Budget pick because it does the basic job in a compact two-pack: place one monitor in each of two small storage areas and check temperature and humidity at a glance. Good Prints 3D found it useful for passive humidity checks in filament boxes, dry bins, and backup-spool storage, without the complexity of an app. Buyers likewise praise the readable display, compact format, and general usefulness. The trade-off is confidence in the exact humidity number: buyer experiences are mixed, and one buyer reported readings more than five points off after a salt-bag check. This is a practical visibility tool, not a precision instrument for decisions that depend on tightly controlled readings.
Who it’s for For people who want two small, no-app monitors for filament storage, a terrarium, a greenhouse, or another enclosed space, and can accept checking trends rather than demanding laboratory-level accuracy.
What sets it apart
- Compact two-pack for monitoring more than one location.
- Clear LCD display that buyers generally find easy to read.
- Good Prints 3D found it practical for passive checks in closed filament-storage containers.
- Simple operation without Bluetooth, Wi-Fi, or a required app.
What to know
- Humidity accuracy is disputed by buyers: some report close or matching readings, while others report large differences or readings they do not trust.
- The display is small and not intended to be read from across a room, according to Good Prints 3D.
- It does not track history, show graphs, send alerts, or dry the material being monitored.
Why this budget two-pack fits small storage spaces
The point of this model is visibility, not automation. Good Prints 3D assessed the two-pack in filament boxes, dry bins, and backup-spool storage, and found the small format useful for checking whether a closed container remains dry. The same review notes that it has no app, graphs, history, or remote alerts. That makes it easy to place and read, but unsuitable if you need a record of changing humidity or a notification when conditions move out of range.
The two-unit format also suits side-by-side or separate checks. One buyer paired the units in different areas for several days and found them accurate relative to one another, while noting that the humidity readings might not match another brand. That is useful for comparing locations, but it does not establish which device is correct.
What buyers report
What the buyers and the named review found matters most in everyday use:
- Buyers describe the LCD as clear and the unit as compact, including for monitoring filament humidity. (comes up often) JEDEW ROUND on Amazon.ca
- Several buyers say the units work as expected or read accurately enough for their use; one paired them for days and found them consistent with each other. (comes up often) JEDEW ROUND on Amazon.ca
- Buyers disagree about accuracy. Some report readings that vary between units or cannot be trusted; one reports a difference of more than five points after a salt-bag check. (comes up often) JEDEW ROUND on Amazon.ca
- Good Prints 3D found the no-app format convenient for a passive check inside filament boxes, dry bins, and small storage areas. (comes up often) JEDEW 2-Pack Hygrometer Review: A Cheap Way to Add Humidity Visibility
Use it for a quick check, not a critical measurement
The strongest case for the JEDEW ROUND is a nearby, readable indication of conditions inside a small container. It can tell you whether two storage areas look broadly similar and whether humidity appears to be moving in the direction you expect. The buyer reports support that kind of relative monitoring, especially for filament storage.
The important limit is accuracy. Amazon's buyer summary is divided: 16 of 28 accuracy mentions are favorable and 12 are unfavorable. Some buyers call the readings precise; others say they vary substantially or cannot be trusted. Keep that disagreement in proportion: it is a concern raised by a minority of buyers, but it matters if your use depends on an exact humidity value. The display also does not go below 10% relative humidity, a limit mentioned by buyers.
