Thermometer, Wall, Plastic Body

Quick Answer: The Thermometer, Wall, Plastic Body is a room thermometer in which a liquid-in-glass tube is mounted in a plastic body carrying the printed scale, made to hang on a wall. A wall thermometer gives an at-a-glance reading of air temperature in labs, classrooms, stores, clinics and homes.

Placing It So It Tells the Truth

A wall-mounted thermometer measures the air immediately around it, so placement decides whether the reading means anything. Mount it on an inside wall at about eye height, away from windows that catch the sun, radiators and heaters, air-conditioner outlets, lamps, refrigerator exhausts and doors that open onto corridors. Outside walls cool at night and warm in the afternoon, and a thermometer on them follows the wall rather than the room.

The plastic body protects the glass tube and holds the scale close to the thread for easy reading, and it is lighter and less likely to shatter on impact than a glass-fronted frame. It is meant for air, not for immersion. The listing does not say whether the tube holds a coloured spirit or another liquid, whether the scale is Celsius only or dual, or its range; these matter if you need to read cold store temperatures.

It is the everyday indoor counterpart of the plastic-backed thermometer in the biology range, which is used for field and weather studies. Where you want the day’s highest and lowest temperatures instead of the present one, choose the maximum and minimum thermometer.

Specifications

Applications

• Daily room-temperature logs in chemical stores and reagent rooms
• Classroom displays for teaching students to read a Celsius scale
• Monitoring wards, pharmacies and dispensaries where medicines are kept at room temperature
• Checking that instrument, server and balance rooms stay within their working range

Care & Handling

• Clean the plastic body with a damp cloth; solvents can cloud or crack some plastics.
• Keep the wall thermometer out of direct sunlight, which fades the printed scale and heats the tube.
• Hang it at eye level so readers do not look up at the thread and misread it through parallax.
• Look for gaps in the thread after moving it between rooms.

Frequently Asked Questions

Where is the right place to hang a wall thermometer?

On an inside wall at about eye height, in shade, with air able to circulate around it. Avoid windows, heaters, lamps, air-conditioner outlets and the back of refrigerators.

Can it be used outdoors?

Only in shade and shelter, such as under a veranda or inside a ventilated screen. Direct sun heats the plastic body and the tube and gives readings far above air temperature, and ultraviolet light ages the plastic.

Why does it read differently from the air-conditioner display?

The air conditioner senses air at its own intake, often high up near the unit, while the thermometer shows air at its own position. Temperature varies across a room, so the two need not agree.

How long does it take to show a new room’s temperature?

Allow several minutes after moving it, or longer when it comes from a very hot or cold place, for the tube and body to reach the room’s temperature.

Can it be placed inside a refrigerator?

Only if its scale extends low enough and the body tolerates damp. A thermometer designed for refrigerators is usually a better choice for cold storage.

How should readings be recorded?

Read at the same times each day and write the value, time and initials on a log sheet beside the thermometer, noting any action taken if the value falls outside the acceptable range.
