Frequently asked questions about the Measuring devices and thermometers category
What are Measuring devices and thermometers and what are they used for?
Measuring devices and thermometers are tools for accurate measurement of length, distance, temperature and humidity: measuring tapes (1–50 m), folding rules, laser distance meters up to 50 m, and wireless thermo-hygrometers. They are used in construction, installation and home maintenance to ensure precision and correct environmental conditions.
Which measuring tape should I choose for construction: 3 m, 5 m, 10 m or 50 m?
Choose tape length by task: 3–5 m (12–25 mm wide) for interior measurements; 10–50 m for exterior and long distances. On-site prefer wider (25–32 mm) tapes and magnetic hooks for attachment and better blade stiffness.
How does the Tamo LD50 laser distance meter differ and up to what distance is it accurate?
The Tamo LD50 measures distances up to 50 m with typical accuracy of a few millimetres per metre (model-dependent). It’s ideal for quickly measuring length, area and volume where physical access to endpoints is limited.
What types of digital thermometers exist and what should I look for when choosing?
Digital thermometers come as indoor, outdoor, wireless-sensor models and combined thermo-hygrometers. Look at measurement range, accuracy, wireless sensor compatibility and extra features like clock/alarms — Kenner DT series is commonly used for home and garden.
What is a mason’s line (müürinöör) used for and what diameters are available?
A mason’s line is used for marking straight lines in masonry, alignment and facade layout. Available diameters are 1.0–2.0 mm and lengths 50–100 m; thinner lines (1.0–1.7 mm) are easier to tension, thicker ones are more durable for long runs.
Which detector should I choose to find hidden cables and pipes?
Choose a detector by target type: basic units detect metal and live wires, advanced models (Bosch GMS 100M, Stanley) distinguish metal, wood and voids. Check detection depth and available modes (metal/wood/void) for accurate wall diagnostics.
When should I choose a wooden folding rule or a plastic one?
A wooden folding rule (Hultafors 2 m wood) stays straight and is preferred for precise joinery. A 2 m plastic rule is lighter, moisture-resistant and more practical on construction sites and outdoors.
Is a magnetic measuring tape suitable for measuring around metal profiles?
Yes. Magnetic tapes (Novipro, Komelon) attach to metal profiles, making one-handed measurements easier. Ensure the magnet is strong and the tape width provides sufficient stiffness for accurate readings.
How important is measuring tape width for accuracy and durability?
Tape width affects stiffness: for accurate long measurements choose 25–32 mm widths. Narrow tapes (12–16 mm) suit short indoor jobs but will bend on longer spans, reducing accuracy.
Which measuring tool do I need to monitor room humidity and temperature?
Use a thermo-hygrometer (e.g. Kenner DT-309) that measures both temperature and relative humidity. Look for models with current/max memory and support for external sensors for broader monitoring.
