• Temperature range: 68°F–212°F
• Humidity range: 0%–100% RH

Large, Easy-to-Read Dial

The 3.7-inch display includes clear scales, large numbers, and a high-contrast red pointer. Anti-glare glass improves visibility in bright light and heavy steam.

Two Installation Options

Choose the setup that works best for your sauna:

• Wall-mounted for permanent traditional or infrared saunas

The adjustable lanyard extends from approximately 5 to 21 inches to accommodate different window and hanging heights.

Rotatable Two-Way Viewing

The dial can be rotated inward or outward, allowing readings to be viewed from inside or outside the sauna depending on the installation.

Battery-Free Mechanical Operation

The mechanical design requires no batteries, charging, or electrical connection. This helps reduce the risk of electronic failure in high-temperature sauna environments.

How to Install

Wall Installation

Mount the unit in a visible location away from direct contact with the sauna heater, steam outlet, or water source. Position it near seated head height for more representative readings.

Lanyard Installation

Adjust the lanyard to the desired length and hang the meter securely from a sauna window, hook, or frame. Rotate the dial to face inward or outward depending on where you want to read it.

Important Placement Information

For the most consistent results, avoid placing the meter directly above or beside the sauna heater, as extreme localized heat may affect the reading. Allow the unit time to adjust after installation or when moving it between environments.

Care Instructions

Wipe the housing and dial with a soft, dry or slightly damp cloth. Do not submerge the unit in water or apply harsh cleaning chemicals directly to the dial.
