Two-pack probe hygrometer for reptiles

This two-pack supplies two mini digital hygrometer thermometers, each with a remote sensor probe on a 59in cable and an LCD display. They measure temperature in Fahrenheit from -58 to 158 and humidity from 10% to 99% RH. Accuracy is ±2 for temperature and ±5% RH for humidity, with readings refreshed every 10 seconds. Each unit runs on two included LR44 button cells and measures 1.89 x 1.13 x .6 inches.

Replaces single-point gauges in sealed enclosures

The external probe lets you place the sensor inside a terrarium, incubator, greenhouse or guitar case while the display stays outside, removing the need to open the container for a reading. The jump is worth it when you need simultaneous temperature and humidity tracking in multiple enclosures or when a single analogue dial can no longer provide the ±2 temperature accuracy these units deliver.

Suits hobbyists monitoring several small habitats

Keepers of reptiles, plants or instruments who want Fahrenheit readouts and a 1.5 metre probe reach will find the pair convenient. Buyers who need water-resistant probes for aquariums, Celsius display, data logging or calibration certificates should look at other products.

Questions about this item

How much clearance does the 1.89 x 1.13 x 0.6 inch main unit need for mounting?

The main unit measures 1.89 x 1.13 x 0.6 inches (48 x 28.6 x 15.2 mm), so allow at least that footprint plus space for the 59 inch (1.5 m) probe cable to route without sharp bends.

What is the correct way to place the external probe, and what mistake should I avoid?

Position the probe tip where you want the reading; the unit samples every 10 seconds. Do not submerge the probe — it is not water-resistant and cannot be used in a fish tank.

When will the two included LR44 button cells need replacing?

Battery life depends on usage, but when the LCD dims or readings become erratic, replace both LR44 cells in each unit with fresh ones of the same type.
