AcuRite Wireless Digital Indoor Thermometer

Best for: Pairing with a humidifier or dehumidifier

Pros

• Temperature and humidity together
• Daily high and low records
• Wall, stand or fridge placement

Cons

• ±1.1°C temperature accuracy
• No backlight listed

The AcuRite Wireless Digital Indoor Thermometer and Hygrometer (model 00613) is a compact indoor monitor, 3 inches tall and 2.5 inches wide, that shows temperature in Fahrenheit or Celsius and relative humidity on one screen. A humidity level icon tells you whether the room is high, low or ideal, and it keeps daily high and low records for both temperature and humidity so you can see how conditions change overnight.

The listing names a humidity range of 16% to 98% RH and a temperature accuracy of ±1.1°C; it does not specify humidity accuracy. It runs on AAA alkaline batteries and can be mounted on a wall, stood upright or placed on a metal surface like a refrigerator. “Wireless” here means it has no cords, not that it connects to Wi-Fi or a phone app.

AcuRite pitches it as a partner for humidifiers and dehumidifiers, and that is exactly who it suits: someone who wants to check whether a machine is doing its job. If you need tighter accuracy, the Pro models further down list ±2% RH.

AcuRite Wireless Indoor Outdoor Temperature

Best for: Replacing a matching AcuRite outdoor sensor

Pros

• Indoor or outdoor use
• A-B-C channel switch
• Works with AcuRite Access

Cons

• Needs compatible display, sold separately
• Batteries not included

The AcuRite Wireless Indoor Outdoor Temperature and Humidity Sensor (06002M / 592TXR) is different from everything else here: it has no screen. It is a remote sensor that sends temperature and humidity readings wirelessly to a compatible AcuRite indoor display or weather station, which is sold separately. It can also work with AcuRite Access (sold separately) so you can check readings from your phone, computer or tablet.

The listing stresses compatibility: check the back of the sensor you are replacing for model numbers 00592TX, 00592TXR, 06002M, 06002RM or 11126-592TXR, and contact AcuRite support if unsure. It has an A-B-C switch, which sets the channel so multiple sensors do not get mixed up on one display. Specs list ±2°F temperature accuracy, a sensing distance of 100 meters, a 16-second response time and a hole for hanging it on a nail. It needs 2 AA alkaline or lithium batteries, which are not included.

This is for people who already own an AcuRite display and need a replacement or extra outdoor sensor, not for first-time buyers wanting a standalone gauge. Anyone shopping for a full indoor and outdoor setup can read our wireless weather station guide for the bigger picture.

The AcuRite 01139M Pro Humidity Meter and Thermometer adds one thing most small gauges lack: a backlight button, so you can read it in a dark nursery or closet. It detects changes in temperature and humidity every 10 seconds and shows both 24-hour and all-time record highs and lows.

The description lists accuracy of ±0.5°F for temperature and ±2% RH for humidity, the tighter figures of the Pro line. It has a magnet on the back and a tabletop design, and the listing names plants, cigars and guitars as things it can help protect. It comes with a limited one-year warranty and includes a comfort meter.

Choose this if you want Pro-level accuracy and need to read it at night. If you want an alert when humidity drifts out of range, the 01080M below adds alarms.

The AcuRite 01080M Pro Accuracy Temperature and Humidity Gauge in black has the widest stated range in this guide: 1-99% RH and -4 to 158°F. It lists ±0.5°F and ±2% RH accuracy, updates every 10 seconds and keeps 24-hour and all-time highs and lows.

Two features set it apart. First, programmable high and low humidity alarms warn you when conditions leave the range you choose. Second, a manual calibration option lets you adjust the reading if you compare it against a reference. A colored LOW, OK and HIGH indicator at the top of the screen shows blue, green or red at a glance. It sits on a tabletop stand or sticks on with a magnet.

This suits owners of guitars, humidors, collections or anything else where humidity matters and an alert is useful. For a plain comfort check in a bedroom, a simpler model will do.

Best for: Nurseries and living rooms in white

Pros

• Clear comfort meter scale
• Per-room calibration
• Tabletop, wall or magnet

Cons

• Wider ±4% error at extremes
• No alarm listed

The AcuRite Humidity Meter Hygrometer and Indoor Digital Thermometer (01083M) is a white 3 x 2.5 inch gauge suggested for living rooms, baby nurseries, kitchens, greenhouses and wine cellars. Its standout is a comfort meter in the middle of the display: a sliding arrow points to low (below 30%), OK (30% to 50%) or high (above 50%) on a blue, green and red scale.

The listing is precise about accuracy: ±0.5°F, ±2% RH between 10% and 90% RH, and ±4% RH at the extremes (0-9% and 91-99%). It measures every 10 seconds, can be calibrated for each room, runs on 2 AAA alkaline batteries, carries a 1-year limited warranty and can sit on a table, hang on a wall or attach with a magnet.

This is a great fit for new parents or gift-givers who want something that looks neat and reads clearly. It lacks the programmable alarms of the 01080M.

The AcuRite 00325A2 Indoor Thermometer and Hygrometer is the most basic model here. It shows current temperature and humidity, a humidity comfort level icon, and daily high and low records. It has a sleek tabletop design with a magnet on the back.

The listing gives a humidity range of 20-95% RH, an upper temperature limit of 122°F and a temperature accuracy of ±1°C; humidity accuracy is not listed. It uses alkaline batteries at 3 volts. The description suggests bedrooms, rec rooms, RVs, wine cellars and cigar humidors.

It suits a first-time buyer who just wants to know if a room is too dry or too damp. If you need the tight ±2% RH accuracy, step up to one of the Pro models.
