Four-Pack Mini Monitors

This set contains four compact hygrometer thermometers that display both temperature and humidity on a round LCD. Each unit ships with a button cell already installed so it works straight from the package. The small footprint suits tight spaces such as jars, enclosures or instrument cases.

±1 °F Temperature Accuracy

The sensor delivers temperature readings within plus or minus one degree Fahrenheit and humidity within two percent relative humidity. Readings refresh automatically every ten seconds and can be toggled between Fahrenheit and Celsius with a dedicated switch.

Embedded or Tape Mounting

A cut-out opening lets the meter sit flush in a panel or lid, while the supplied double-sided tape offers a quick stick-on alternative. The operating range spans minus fifty-eight to one hundred fifty-eight degrees Fahrenheit with humidity coverage from ten to ninety-nine percent RH.

Questions about this item

What does the ±1°F accuracy mean when I am using the meter?

The sensor reports temperature within one degree Fahrenheit of the true value, so a displayed reading is never more than one degree away from the actual temperature.

How does the °C/°F button change the display and what range does it cover?

Pressing the button toggles the read-out between Fahrenheit and Celsius across the full -58 to 158 range.

What size opening or surface do I need to mount one of these units?

Each unit measures 1.79 in by 1.79 in by 0.61 in and can be recessed into a matching cut-out or stuck on with the supplied double-sided tape.
