Ungraduated Thermometer - Red Spirit Filled: (L)205mm
HP00053553
Product code: HP00053553
Product Description
Ungraduated Partial Immersion Red Spirit Filled Laboratory Thermometer:
-10°C to +110°C (L)205mm
The ungraduated spirit filled thermometer uses specially selected filling materials which are coloured red on a white back glass. Thermometer normally supplied with the non-roll cap with ring.
Specification:
- Range (°C): -10°C to +110°C
- Division: 1.0°C
- Length: 205mm
- Filling: Red Spirit
- Immersion: Partial, Immersion is 76mm.
- Accuracy: +/-1.0°C at 35°C
- Product Material: Glass Tube: Kerosene filled
This plain ungraduated thermometer allows students to produce and mark on their own scales.
- Immersion depth: Thermometers available are total or partial immersion. Total immersion thermometers are designed to give correct readings when completely immersed in the medium under test. Partial immersion thermometers are calibrated to read correctly when immersed to defined depth (usually 76mm)
- Faults during transit. Thermometers may develop faults during transit or when otherwise subject to undue vibration. Most faults can be corrected by following these suggestions:
- Gas trapped in bulb. Tap any bubbles of gas into the top of the bulb then cool the bulb in a suitably cold medium. As the spirit contracts the trapped gas should be forced above the spirit
- Broken thread. The spirit thread may be re-joined by cooling
- Detached spirit at the top of contraction chamber. Cool the bulb until spirit comes down into the contraction chamber. The side of the stem should be gently tapped until the detached spirit forms a globule on the wall of the contraction chamber. By gently heating the bulb this spirit can be re-joined to the main column
- Detached spirit in the expansion chamber. Tap the top of the stem until the detached spirit collects at the top of the capillary. Very carefully heat the thermometer. As the expanding spirit forces gas into the expansion chamber, continue to tap the stem in order to keep the detached spirit on top of the capillary
- Maximum/minimum thermometers. For broken threads, hold at the top and give a sharp shake
